High Temperature Composites Using Schiff's Base Pyropolymer Matrices
Abstract
Two acetylene functional Schiff's base pyropolymers have been evaluated as matrix materials for fiber reinforced composite materials. Autoclave processing techniques were developed to produce high quality laminated composites. These matrix resins can be made conductive through post-cure heat treatments and were studied in a conductivity range from 10-10 to 10 S/cm. The insulating resin composites have very stable mechanical properties up to 300 C; however, these properties are significantly lower than state-of-the-art polyimides. The post-processing heat treatments required to make the pyropolymers conductive, also caused extensive transverse matrix cracking in the laminates.
