CRG company has developed a new high temperature resin (service temperature is 300-450 ℃)
with ultra-low flammability, heat release and smoke release, similar to
the workability and cost of epoxy resin. In addition, it can be curable
into a thermoplastic state at temperatures below 110 ℃, when the temperature is higher than 110 ℃ it will crosslinking. it can be converted into an almost pure carbon material at higher temperatures.

resin combine with fiber reinforcement using conventional processing
technology to provide for low-cost, high-temperature structural
composites potential. Water is the only volatile generation thing, it
does need to be managed porosity, polymer analogous condensation
reaction, such as phenolic resins and polyimides. However, preliminary
tests MG resin composites showed lower amplitude compared to the heat
release phenolic resin.

test sample produced by glass fiber and carbon fiber fabrics and carbon
fiber mat and hand lay-up by vacuum injection. Carbon fiber panels and
carbon mat plate is autoclave at 200-250 ℃ and 2 hours post-curing. Fiberglass chopped strand mat sample cured in an oven at 250 ℃.
MG3000 test sample was prepared in a similar manner. Breadboard use
abrasive fibers and resin production, and strive to explore low-density
material ablation and thermal protection systems for (TPS) for the
potential use spacecraft. Although the polymer formulation, processing
and curing cycle to continue to decrease further optimized porosity,
overall, the resulting composite exhibits good.
