Abstract
The aging mechanism of phenolic resin‐nitrile butadiene composites has been investigated. Using solvent extraction and chromatographic analysis of the extract using dual detectors it was shown that the rubber component was well crosslinked. The phenolic component however was not fully crosslinked, although it would have been expected from the cure conditions employed. With increased time, at temperatures near ambient, the phenolic resin continued to react and caused increased brittleness of the composite.

A novel method has been developed to toughen phenolic resin using phenoxy resin. Phenoxy resin was dissolved in phenol to form a glutinous mixture at 110ЊC, and an acid catalyst ( p-toluene sulfonic acid, PTSA) was utilized to reduce the viscosity of mixture. The mixture was blended with resole-type
The pyrolysis of carbon/phenolic composites is a critical step in the manufacture of high temperature carbon/carbon components. Understanding the reaction kinetics of the pyrolysis reactions is essential for advancement in the processing of carbon/carbon materials. To increase the understanding of t
