SPECIALTY ANHYDRIDES FOR HIGH-PERFORMANCE COMPOSITES

摘要

Specialty anhydrides are key components of several materials used in high-performance composites. The anhydrides function as monomers for polymer synthesis and as intermediates for resins used in demanding environments. Specialty anhydrides are important raw materials for polyimides, poly(amide-imides), epoxies and hybrid resin systems. These materials can be formed into a range of articles with direct composite applications including films, foams, fibers, adhesives and molded parts. The resulting products have advantages over conventional materials in terms of thermal oxidative stability, chemical resistance, mechanical properties, electrical resistance, weight reduction and wear resistance. Several relevant specialty anhydrides will be discussed, with a focus on their areas of application and use in high-performance composites.
