Composite automobile bumper

Abstract

The invention relates to a composite automobile bumper which consists of a gel coat layer, a structure layer, an adhesive layer, a primer layer, a foam aluminum layer and a collision bumper, wherein the gel coat layer adopts neopentyl glycol phenylene resin; the structure layer comprises a plurality of resin layers and a fiber layer; the adhesive layer and the primer layer both adopt epoxy resin as main material; the foam aluminum layer adopts 6061 aluminum alloy foam aluminum; and the collision bumper is a gas-liquid bumper. The composite automobile bumper has the advantages of good impact resistance, long service life, easy repair, high strength, high corrosion resistance, good processing performance (capable of being sawn, planed and drilled) and good mechanical performance, as well as light weight and low cost, thereby being widely popular with users. Therefore, the composite automobile bumper integrates the characteristics of safety, high efficiency, light weight, corrosion resistance and beautiful appearance.

Description

technical field [0001] The invention relates to a composite automobile bumper, which belongs to the automobile bumper of composite material and composite structure, in particular to a composite bumper capable of absorbing and reducing impact force and vibration force when an automobile collides with an accident. Background technique [0002] Existing automobile bumpers generally use injection-molded bumpers. Plastic bumpers can only prevent minor collisions, and cannot effectively slow down the huge collision force generated by the vehicle during operation. The accident loss is very heavy; there are also bumpers made of section steel. , when a collision accident occurs, head-to-head, impact, and vibration are transmitted to the car at once, causing many accidents of car crashes and injuries; there is also a bumper made of steel and plastic, and its large collision effect is equivalent to that of a steel bumper. Just looks nicer. Contents of the invention [0003] The purp...
