4 Pre-conference Seminar September 27, :30-11:30 AM (Separate fee required) Out of Autoclave Processing for Aerospace Structures The development of out of autoclave (OOA) capable prepreg materials for aerospace structures since the early 1990 s is reviewed. The latest generation of OOA capable materials offers the same performance as traditional autoclave cure materials and significant advances in processing knowledge for both monolithic and honeycomb sandwich structures have been achieved. The potential benefits of OOA processing include the removal of size and shape constraints imposed by the autoclave, the potential to build large integrated structures with fewer parts and the expansion of the available subcontractor base. As with autoclave curing materials, a range of products is needed with a different balance of properties for different applications. Public domain shared databases have been a key enabler in the introduction of new OOA materials and offer a more cost effective route to qualification than the traditional end user specific qualifications. The emphasis to date has been on epoxy based materials however OOA processing can also be applied to other resin chemistries such as BMI s and the current status of material development is reviewed. Instructor: CHRIS RIDGARD is Vice President, Research & Technology, at the Advanced Composites Group of UMECO. Chris is a composites engineer with 32 years experience in the industry. He joined British Aerospace, Manchester England in 1979 and worked on some of the first applications of composites in aircraft structures. He joined the Advanced Composites Group, Heanor England in 1986, moving to the newly established Tulsa Oklahoma USA facility in He was involved in the development of low temperature curing composite materials and the application of the first out of autoclave processable prepregs to aerospace structures. In recent years he has been working with the latest generation of aerospace structural prepregs and the production of shared material property databases.

5 Opportunities for High Temperature PMC's at GE Aviation DR. LARA LIOU, Ph. D., Lead Engineer, PMC Development, GE Aviation Current applications New potential applications Performance and cost requirements Modified Phenolic Prepregs for Interiors Applications with Critical Flame, Smoke and Toxicity Requirements CARL VARNERIN / Vice President Reasearch & Development, Barrday Advanced Material Solutions Test Specimen Preparation Technical Requirement Mechanical Test Results Flammability Test Results Steerable Cure Latent Epoxy Systems for Large Composite Parts BERNIE FU, Ph.D. Industry Specialist, BASF Corporation Abstract Wind blades are one of the fastest growing applications for thermoset composites. Among the various manufacturing technologies, prepreg and infusion are the most popular manufacturing technologies currently used by wind blade manufacturers. With wind blades getting longer and lighter, traditional epoxy systems are reaching the limits of its processing parameters and posing several challenges in manufacturing. This presentation will review some latest developments in resin systems to achieve a balanced processability and performance. By using certain latent technologies, a tailored epoxy system allows longer working life and quick reaction at targeted temperatures. Benefits of such system include the ease of processing, reduced cycle time and better quality of composites.

6 Thermoplastic vs. Thermoset Matrices for High-Temperature, Out-of-Autoclave Composites Applications CHARLIE COSTELLO, Ticona Engineering Polymers ABSTRACT The high-temperature, high-mechanical performance end of the composite materials spectrum socalled advanced composites has long been dominated by thermoset matrices, primarily epoxy and urethane chemistries with carbon or aramid fiber reinforcements. However, that is starting to change as thermoplastics resin suppliers begin to investigate and more aggressively position their own hightemperature offsets in this segment. While no single resin chemistry does it all, the availability of thermoplastics options provides a host of design, processing, cost, weight, and environmental benefits to those seeking new options in the advanced composites arena. This is particularly true for processors without autoclave or without sufficient autoclave resources to process traditional advanced composite matrices. This paper will cover some of the major high-temperature resin families in both thermoplastic and thermoset matrices and will compare and contrast performance and processing benefits and challenges. Properties of VARTM-Fabricated RTM-370 Composites FRANK W. HARRIS, President & CEO, Akron Polymer Systems, Inc. Authors Kathy C. Chuang Jim M. Criss Eric A. Mintz Dong Zhang Frank W. Harris NASA Glenn Research Center, Cleveland, OH M & P Technologies, Inc. Marietta, GA Clark Atlanta University, Atlanta, GA Akron Polymer Systems, Akron, OH Akron Polymer Systems, Akron, OH RTM-370 is an ethynyl end-capped, imide oligomer prepared from 2,3,3,4 -biphenyl dianhydride ( a- BPDA), 3,4 -oxydianiline (3,4 -ODA) and 4-phenylethynylphthalic (PEPA) in the absence of solvent in the melt. The free-flowing powder resin has a low melt viscosity (10-30 poise) at 280 C and a pot-life of 1-2 h at this temperature. The resin when cured at 371 C displays a glass transition temperature of 370 C. The resin has been fabricated previously into T carbon fabric composites using resin transfer molding (RTM) techniques. These composites exhibit excellent mechanical properties up to 327 C (620 F) and outstanding property retention after aging at 288 C (550 F) for 1000 hrs. In this presentation, the fabrication or RTM 370 composites using vacuum assisted resin transfer molding (VARTM) in vacuum bags without a mold will be discussed. The mechanical properties of the composites fabricated using VARTM will be compared to those of composites fabricated using RTM.

7 Commercialization of a New Bismaleimide Capable of Void Free Laminates via VARTM and Prepreg Manufacturing ROBERT STRATTON, Stratton Composite Solutions/Raptor Resins New Bismaleimide Formulation (what s different) Processes and Techniques Range of Applications Market Potential and Ongoing Efforts Robert Stratton and Raptor resins have developed the next generation Bismaleimide resin system. The presentation will explore the applications and markets the material of this new material. There are several new markets for a material with these types of process parameters and properties, from aerospace to the oil industry. The processing methods for a number of applications to date will be discussed along with where we are see the market in the next few years for the material. The Future of Bio-based High Performance Resins DWIGHT RUST, President, DARCO Consulting, Inc. An overview of the plastics market and high performance resins The driver for bio-based resins Current market and technical advances in bio-based resins The effect of this technology upon high performance resins The Importance of Sizing in Composite Processing and Properties ANDREW E. BRINK, YVES DE SMET, Michelman, Inc. Fibers & Composites Business Unit A sizing formulation, as applied to a reinforcing fiber, has four critical functions. It must protect the fiber during and after production, impart processability for fiber manufacturing, enable the composite fabrication and provide good interfacial adhesion between the fiber and the matrix resin. Although the sizing is often less than 1 wt% of the composite its performance is critical to the production and performance of a composite part. This presentation will give an overview of sizing chemistry and provide some real examples of how the sizing can impact processing and composite properties. A few critical differences between carbon fiber and glass fiber will also be discussed.

8 Novel Reactive Finishes for Carbon/Polymer Composites RONALD E. ALLRED / President,, Adherent Technologies Fiber finishes (sizings) have been developed for a variety of polymer matrix composites that impart superior wetting, mechanical properties, and environmental durability. These features are the result of chemical bonding between the carbon fibers and matrix resin at the interface. Interface sensitive mechanical properties of high temperature polyimide matrix composites after moisture saturation and accelerated thermo-oxidative aging experiments will be discussed. Similar properties of carbon/vinyl ester composites will also be presented. Results show that the composites containing the new reactive finished fibers exhibit superior interface sensitive mechanical properties and fracture toughness dry and after environmental exposures.
