Abstract

The invention provides an aramid-fiber-reinforced flame-retardant unsaturated polyester composite material, belonging to the technical field of high-molecular material. The material is composed of the following raw materials by weight parts: 60-65 parts of unsaturated polyester resin, 16-51 parts of a low contraction additive, 0.6-1 part of an initiator, 0.006-0.01 parts of a polymerization inhibitor, 0.12-0.18 parts of a thickening agent, 160-220 parts of filling materials, 3-6 parts of a fire retardant, 2.2-2.6 parts of a mold lubricant, 32-36 parts of fiber powder and 8-10 parts of aramid fiber. The aramid-fiber-reinforced flame-retardant unsaturated polyester composite material has characteristics of strong intensity, low contraction and high toughness.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an aramid fiber-reinforced unsaturated polyester composite material. Background technique [0002] Known for its high strength, aramid fiber is mainly used in the reinforcement and toughening of high-tech products. Such as body armor and so on. But so far no one has thought of combining the high strength of aramid fibers in the above-mentioned composite materials. Contents of the invention [0003] The task of the present invention is to provide a flame-retardant unsaturated polyester composite material reinforced by aramid fibers with outstanding strength, toughness and low shrinkage. [0004] The task of the present invention is accomplished like this, a kind of aramid fiber reinforced flame-retardant unsaturated polyester composite material, it is made of the raw material of following parts by weight: [0005] 60-65 parts of unsaturated polyester res...
