Problems solved by technology

[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. It's just more beautiful

Embodiment Construction

[0015] A composite automobile bumper comprises an outer layer 1 and a collision buffer 2, the outer layer 1 is composed of a gel coat layer 3, a structural layer 4, an adhesive layer 5, a primer layer 6, and a foamed aluminum layer 7, and the gel coat layer 3 is Neopentyl glycol-isophthalic resin;

[0016] Structural layer 4 is 5 layers, namely resin layer, fiber layer, resin layer, fiber layer, resin layer; the formula of resin layer is to add 20 grams of epoxy curing agent T31 and 15 grams of diluent to 100 grams of epoxy resin E-44 Anhydrous ethanol; fiber layer is fiberglass cloth;

[0017] Adhesive layer 5 and primer layer 6 all adopt epoxy resin as the main material, and the formula of adhesive layer 5 is that 100 grams of epoxy resin E-44 add 20 grams of dehydrated alcohol, 70 grams of furyl methylene acetone, diethylene glycol 15 grams of ethylene triamine; the formula of primer layer 6 is 100 grams of E-44 epoxy resin, 20 grams of absolute ethanol, 12 grams of ethyle...

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...
