Abstract

The invention relates to the field of helmet materials, in particular to a fiber-reinforced motorcycle helmet composite plastic and a preparation method. Jute fibers are loosened through steam explosion treatment, the loosened jute fibers are provided with good micropores, a foaming agent is arranged in the micropores of the jute fibers, then the jute fibers are coated with thermosetting epoxy resin, during heat treatment of a two-stage fluidized bed, gas is generated by the internally-arranged foaming agent, the micropores are reserved, meanwhile, the epoxy resin is heated and cured to form firm coating coated fibers, and the obtained fibers are the loosened jute fibers with the micropores; and after the jute fibers are coated with the thermosetting resin, compatibility and dispersion ina fiber polycarbonate / ABS system are facilitated, the loosened jute fibers are protected by the thermosetting resin, the micropores of the jute fibers cannot be blocked during later pelletizing, and the good micropores of the obtained composite plastic are reserved in a finished helmet outer shell. The helmet outer shell has excellent low-weight and buffering characteristics while the strength ofthe helmet outer shell is achieved.

Description

Technical field:

[0001] The invention relates to the field of helmet materials, in particular to a fiber-reinforced motorcycle helmet composite plastic and a preparation method. Background technique:

[0002] The helmet is a head protection device with plastic as the main material, which is mainly composed of three parts: the shell, the buffer layer lining and the suspension device. The shell is generally made of hard plastics such as ABS or PC with good wear resistance and compression resistance, and carbon fiber composite materials or metal materials are also used. This layer requires high hardness, high rigidity, and wear resistance, which helps to resist the penetration of sharp objects. At present, most of the helmet shell materials are reinforced, such as carbon fiber and glass fiber reinforced plastics. However, when used as a helmet shell material, in addition to reinforcement, it is more important to realize the reinforcement while ensuring the good cushioning and...
