8 . Introduction. Scope The test methods and results described in this document are intended to provide basic composite properties essential to most methods of analysis and are consistent with MIL-HDBK-7-F Composite Materials Handbook for Polymer Matrix Composites. This report contains material property data of common usefulness to wide range of projects. The lamina and laminate material property data have been generated with FAA oversight through FAA Special Project Number SP464WI-Q and also meet the requirements of NCAMP Standard Operating Procedure NSP ; the test panels, test specimens, and test setups have been conformed by the FAA and the testing has been witnessed by the FAA. However, the data may not fulfill all the needs of any specific company's programs. Specific properties, environments, laminate architecture, and loading situations that individual companies may require additional testing. The use of NCAMP material and process specifications do not guarantee material or structural performance. Material users should be actively involved in evaluating material performance and quality including, but not limited to, performing regular purchaser quality control tests, performing periodic equivalency/additional testing, participating in material change management activities, conducting statistical process control, and conducting regular supplier audits. The applicability of NCAMP material property data, material allowables, and specifications must be evaluated on caseby-case basis by aircraft companies and certifying agencies. NCAMP assumes no liability whatsoever, expressed or implied, related to the use of the material property data, material allowables, and specifications. This report contains material property data only. Statistical analysis of the data including the calculations of b-basis values is given in a separate report Hexcel 855 AS4 Unidirectional Qualification Statistical Analysis Report panels were fabricated by Cessna Aircraft Company, 58 E Pawnee, Wichita, KS 678. The qualification material was procured to NCAMP Material Specification NMS 8/ Rev - Initial Release February 6, 7. The qualification test panels were cured in accordance with Baseline Cure Cycle (M) of NCAMP Process Specification NPS 88 Rev A Cure Cycle M. The NCAMP Test Plan NTP 8Q was used for this qualification program. Part fabricators that wish to utilize the material property data, allowables, and specifications may be able to do so by demonstrating the capability to reproduce the original material properties; a process known as equivalency. More information about this equivalency process including the test statistics and its limitations can be found in Section 6 of Page 8 of 78

9 DOT/FAA/AR-/9 and Section 8.4. of MIL-HDBK-7-F. The applicability of equivalency process must be evaluated on program-by-program basis by the applicant and certifying agency. The applicant and certifying agency must agree that the equivalency test plan along with the equivalency process described in Section 6 of DOT/FAA/AR-/9 and Section 8.4. of MIL-HDBK-7-F are adequate for the given program. Aircraft companies should not use the data published in this report without specifying NCAMP Material Specification NMS 8/. NMS 8/ have additional requirements that are listed in its prepreg process control document (PCD), fiber specification, fiber PCD, and other raw material specifications and PCDs which impose essential quality controls on the raw materials and raw material manufacturing equipment and processes. Aircraft companies and certifying agencies should assume that the material property data published in this report is not applicable when the material is not procured to NMS 8/. NMS 8/ is a free, publicly available, non-proprietary aerospace industry material specification. The data contained in this report is intended for general distribution to the public, either freely or at a price that does not exceed the cost of reproduction (e.g. printing) and distribution (e.g. postage). Data that is subject to export control regulations, if any, will be made available on a case by case basis through written request to NCAMP..

23 .5.4 Physical Testing The properties in Table - were determined for each panel used for test coupons with the exception of Tg by DMA which were conducted on one laminate per batch from each oven cure conducted where that batch is present. The tests were performed by the National Institute for Aviation Research (NIAR) Composites Laboratory under the supervision of NCAMP.

For these materials, in order to verify Method II is accurate, a minimum of samples per batch were tested by Method I, Procedure B. : Five MHz was used for solid laminates. Panels with anomaly were segregated. Microscopy images may have been taken from questionable areas. NCAMP was involved in the review of all the C-scans. 4: Minimum total of 4 dry and 4 wet for each material system. Table -: Physical Testing Matrix Page of 78

24 .5.5 Environmental Conditioning The following tests were performed by the NIAR Composites Laboratory under the supervision of NCAMP. CTD = -65±5 F, dry RTD = 7± F, room temperature dry ETD = 5±5 F, dry ETW = 5±5 F, wet (equilibrium moisture content) Within each test method and test environment, the failure mode was evaluated immediately after each test by an FAA DER. All tested specimens were digitally photographed after each test in order to pictorially document failure modes. Representative photos are included in the CD accompanying this report. For dry testing, specimens were dried at 6 F±5 F for to hours. After drying, specimens were kept in a desiccator until mechanical testing. Alternatively, the specimens may have been left ambient laboratory condition for a maximum of 4 days until mechanical testing (no drying was required if specimens were tested within 4 days from the date they were cured). Ambient laboratory condition is defined as 7 F± F. Since moisture absorption and desorption rate for epoxy is very slow at ambient temperature, there was no requirement to maintain relative humidity levels. For wet conditioning, specimens were dried at 6 F±5 F for to hours before being conditioned to equilibrium at 6 F±5 F and 85% ± 5%. Effective moisture equilibrium was achieved when the average moisture content of the traveler specimen changed by less than.5% for three consecutive readings which are 7 ±.5 days apart and may be expressed by: W i -W i W b where: W i = weight at current time W i = weight at previous time W b = baseline weight prior to conditioning - <.5 Page 4 of 78

25 When representative specimens could not be measured to determine the moisture content (due to size, fastener and tab effects), traveler coupons of at least by by specimen thickness and weighing at least 5 grams were used to establish weight gain measurements. If the specimens or traveler coupons pass the criteria for three consecutive readings which are 7 ±.5 days apart, the specimens were kept in the environmental chamber for up to an additional 6 days. Alternatively, the specimens may have been removed from the environmental chamber and placed in a sealed plastic bag along with a moist cotton towel for a maximum of 4 days until mechanical testing. Strain-gaged specimens were removed from the controlled environment for a maximum of hours for application of gages in ambient laboratory conditions. Page 5 of 78

26 .5.6 Non-ambient Testing The chamber was of adequate size so that all test fixtures and load frame grips were contained within the chamber. For elevated temperature testing, the temperature chamber, test fixture, and grips were preheated to the specified temperature. Each specimen was heated to the required test temperature as verified by a thermocouple in direct contact with and taped to the specimen gage section. The heat-up time of the specimen did not exceed 5 minutes, + minutes after the specimen unless otherwise specified in individual test summary sheets. The test was started reached the test temperature. During the test, the temperature, as measured on the specimen, was within ±5 F of the required test temperature. For subzero temperature testing, each specimen was cooled to the required test temperature as verified by a 5 thermocouple in direct contact with and taped to the specimen gage section. The test started + minutes after the specimen reached the test temperature. During the test, the temperature, as measured on the specimen, was within ±5 F of the required test temperature.

27 .5.7 Normalization Procedures Most lamina level tension and compression strength and modulus properties, and all laminate level properties were normalized according to nominal cured ply thickness. Lamina level properties that were not normalized include 9º tensile strength and modulus (unidirectional only), 9º compressive strength and modulus (unidirectional only), in-plane shear strength and modulus, Poisson s ratio, SBS, and ILT. After normalizing, data scatter reduced or remained the same. If data scatter increased significantly after normalizing, the reason was investigated. Wherever properties are normalized, both measured and normalized data were reported. For unidirectional materials the fiber areal weight cannot be measured in advance of impregnation, hence Method I of ASTM D7, utilizing acid digestion, will be used to verify the CPT method in accordance with note () of Table -. Method I Fiber Volume (%vol) is and Method Fiber Volume (%vol) is By comparing Fiber Volume values obtained from Method I and Method II, the values are deemed close enough therefore the FAW is close to the nominal of ~9 gsm. Based on the FAW data from Hexcel (Avg ~9 gsm) and our Method I Phys test data (Avg. void content ~ % except for a panel where it is close to 4%) it is appropriate to use the CPT Method for normalization. The average cured ply thickness of.74 inch has been used as the nominal cured ply thickness (CPT) for normalization purpose. The following normalization formula was used: Normalized Value = Measured Value x Measured CPT / Nominal CPT. Page 7 of 78

28 .5.8 Conformity The -batch qualification panels have been fabricated according to the requirements of the test plan and conformed by the FAA. The test specimens and test setups have also been conformed by the FAA. Testing was witnessed by the FAA. Witnessing was delegated to a DER. Mechanical testing was carried out at the National Institute for Aviation Research, Wichita State University. The test setup and procedures were reviewed by NCAMP IAB and NCAMP staff during a facility audit. FAA conformity inspection records and approvals are included in the CD accompanying this report..5.9 Material Pedigree Information The PMC Data Collection Template includes the material pedigree information required, such as material and batch information, as well as panel fabrication record, environmental conditioning, test equipment, and test procedures.

272 9. TMA Results The TMA results were tested at Hexcel. Specimens were taken from the same panels as DMA and wet and dry testing was tested concurrently. NCAMP and Hexcel investigated the close numbers between the dry and wet TMA but no determination was made as to the cause. Below is the discussion that took place at Hexcel. NCAMP is open to further discussion. From Bill Gillam: I do know that drying will occur to some degree during testing and would be dependent on thickness; however in my experience even TMA specimens should still show a knock-down in Tg for wet conditioning. Typically a requirement for the wet conditioned specimens is to keep them submerged in solution right up until the time of sample prep/testing. [NCAMP: Specimens were conditioned and then sent overnight to Hexcel in a sealed plastic bag with a moist towel]. Obviously a thick DMA specimen would retain moisture in the matrix to a higher degree during testing than a thin TMA sliver. I would expect the delta between wet and dry to be greater with DMA than TMA however I would always expect the wet knock-down, even with TMA. Regards, Bill From: Bolke, Robert Sent: Tuesday, June 8, : AM To: Kristin (Strole) Marlett; Gleason, Michael; Lallas, George Cc: Wu, Joy; Gillam, William R. Subject: RE: Dry TMA results Kristin- I put together the TMA scans from March 9 when we tested the Dry specimens and October 9 when we tested the Wet specimens. I agree that it is surprising that the TG for the Wet specimens is higher than for the Dry specimens. I am trying to think of anything that may have caused this. Do you know if the only difference between the samples that were sent to Salt Lake is the Wet conditioning? [Yes that is the only difference]. Do you know if the Wet samples were dried with the Dry samples before they were conditioned? [I am not sure of this but they were dried under the same parameters per the test plan]. Additionally I wonder if the size of sample may have an effect on the difference between the DMA and TMA results. When we do TMA the sample is only a small sliver. It may be possible that the samples was dried during testing while the oven ramped to temperature. The DMA samples are also a lot bigger than the TMA sample and may possibly hold in the moisture better. Rob Bolke Hexcel Corp. robert.bolke@hexcel.com office: Page 7 of 78
