Epoxy resin system for large scale composite structures
Under a grant awarded by the Office of Naval Research and NAVSEA, Triangle Polymer Technologies has developed an advanced epoxy resin system for fabricating glass and carbon fiber reinforced composites via the Vacuum Assisted Resin Transfer Molding process (VARTM).
This hybrid epoxy system is designed for room temperature processing and curable fabrication. This novel, hybrid system has the following performance advantages:
Low viscosity (less than 500 cps) to assure ease of processing via VARTM
Long open time, greater than 4 hours at room temperature
Room temperature cure that affords a Tg > 200F and achieves 98+% of cure
Flame retardant equivalent to DER 510A-40 (Vinyl ester resin)
High strength and fracture toughness
