Triangle Polymer Technologies, Inc / North Carolina AT State University: STTR N064 – 040 - 0400 Composite fabrication via the VARTM process Prepared by Dr. Ronnie Bolick North Carolina AT State University 1) Material System North Carolina AT State University has worked and conducted research in the area of composite materials over the last 20 years. It has worked extensively with the Department of Defense (DoD), NASA, NAV/AIR (Naval Air Force), Federal Aviation Administration (FAA), Air Force Research Laboratories/Materials Directorate (AFRL/ML), Army Research Laboratories (ARL), Clarkson Aerospace, Boeing and Lockheed, the NAVY and the ARMY. The research ranged from composites materials manufactured from carbon, fiberglass and carbon-carbon reinforcements with epoxy and vinyl-ester resins. NCATSU has the ability to manufacture composites using RTM (Resin Transfer Molding), VARTM(Vacuum Assisted Resin Transfer Molding), HVARTM( Heated Vacuum Assisted Resin Transfer Molding) and the Autoclave process. NCATSU also has the ability to develop a molding process to custom fit a material system and/or resin system through it manufacturing and processing experience. AT has worked with Fiber Glass Industries ( FGI, Inc.) and Hexcel Corporation in developing the methodology of improving coating of resins onto the sizing provided by these two companies. A working relationship with the manufacturer’s research laboratories, AT and Triangle Polymer Technologies will strengthen the development process in this endeavor to supply the best product possible. The first phase will involve the use of woven roving and stitched bonded
