Book Description
Studies were conducted to establish the effects of thermo-oxidative and hydrothermal exposure on the mechanical properties of T300 graphite fabric reinforced PMR-15 composites. The effects of hydrothermal exposure on the mechanical properties of HTS-2 continuous graphite fiber composites were also investigated. The thermo-oxidative stability characteristics of T300 fabric and T300 fabric/PMR-15 composites were determined. Flexural strengths of specimens from composites in the as-fabricated and environmentally exposed conditions were determined. The useful lifetime of T300 fabric/PMR-15 composites in air at 316°C was found to be about 100 h. The useful lifetimes in air at 228 and 260°C were determined to be 500 and 1000 h, respectively. Absorbed moisture was found to reduce the elevated temperature properties of both the T300 fabric and HTS-2 continuous fiber composites. The moisture effect was found to be reversible.

Book Description
Polyimides have been available commercially for over 25 years, but are still frequently thought of as new materials, due largely to their performance and high technology end uses, which ensure that levels of research and development remain high. This detailed review describes the synthesis, properties, processing and applications of condensation, addition and hybrid polyimides. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.
