Manufacturing of advanced continuous fiber reinforced composites for high temperature applications

"New resin systems have enabled composites to be considered as attractive alternatives in structural applications that require material to be stronger, lighter and/or more resilient to environmental effects. The current work is on the development of processes to produce continuous fiber reinforced materials from two state of the art resin systems. Two processes were developed to produce continuous fiber reinforced ceramic materials from a preceramic polymer. The first was a vacuum forming process developed using the out-of-autoclave polymer composite manufacturing technique in conjunction with the polymer infiltration and pyrolysis process to produce ceramic composite material of zirconium diboride-silicon carbide reinforced with continuous silicon carbide fibers for use in ultra high temperature applications. A second process was developed using the dry press ceramic manufacturing technique in conjunction with the polymer infiltration and pyrolysis process to produce ceramic composite material of silicon carbide reinforced with continuous silicon carbide fibers for use in high temperature nuclear applications. The materials from these two processes were characterized using microstructure analysis techniques and standardized mechanical testing. The third process produced a polymer reinforced composite from novel thermoset polyurethane. A vacuum assisted resin transfer molding technique was used to produce a composite material from a new two-part polyurethane resin infused into plane weave E-glass fiber mats. The effects on the microstructure and the impact behavior of thermoset polyurethane composite material, exposed to an accelerated UV-aging environment, were assessed. The work performed provides valuable information with respect to the processing of continuous fiber reinforced composites using new materials and processes"--Abstract, page iv.
