▎ 摘　　要

NOVELTY - Polybutylene terephthalate (PBT)-polycarbonate (PC) composite material comprises 20-60 pts. wt. PBT-graphene oxide composite material, 5-40 pts. wt. polycarbonate (PC) resin, 5-20 pts. wt. flame retardant, and 5-40 pts. wt. glass fiber. The PBT-graphene oxide composite material comprises 80-100 pts. wt. PBT resin and 0.2-5 pts. wt. graphene oxide. USE - PBT-PC composite material for engine portion, an electrical housing or a luminaire (claimed). ADVANTAGE - The PBT-PC composite material has excellent thermal conductivity, crystallinity, impact toughness, flame retardance and dimensional stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of PBT-PC composite material, which involves mixing and extruding PBT-graphene oxide composite material, PC resin, flame retardant and glass fiber to obtain the PBT-PC composite material.
