Abstract

The pyrolysis of two high-temperature thermosetting polymers has been studied as potential carbon precursor materials. Both resins are easily processed into shaped and void-free components. The polymers and corresponding pyrolysates exhibit outstanding thermal properties. As the heat treatment is progressively increased, a carbonaceous mass is produced yielding a high char yield. As the pyrolysis temperature was raised to 700°C, the density increased and remained at a fairly constant value to 1200°C. Further heat treatment to 2700°C resulted in a reduction in the density. Shrinkage appears to occur at about the same rate as free volume is being produced within the developing pyrolysates causing collapse to essentially microporous systems. © 1993.
