Abstract

The invention provides a novel light structural material, and a preparation method and application thereof. The novel light structural material comprises a three-layer structure with two fiber reinforcement layers and an intermediate layer, wherein the intermediate layer is positioned between the two fiber reinforcement layers; chopped fiber reinforcement layers are arranged on the side edge surfaces of the three-layer structure; and the intermediate layer comprises the following materials: 30-40wt% of jute fibers, 25-35wt% of polypropylene fibers, 15-20wt% of polyester fibers, 5-10wt% glass fibers, and 5-10wt% of volcanic ash. The novel light structural material has the advantages of light weight, abrasion resistance, noise reduction, and good fire prevention effect and corrosion resistance, and can be widely applied in the fields of automotive inner plaque components, airplanes, toys, and the like.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a novel lightweight structural material and its preparation method and application. Background technique [0002] At present, low-carbon and environmental protection have become the current development trend of the international community. Major developed countries and regions such as Europe, the United States, and Japan have issued strict policies and regulations to encourage and support the development of "environmentally friendly" materials and industries to reduce Pollution and environmental protection, while coping with the looming energy crisis and resource constraints, biomass plant fibers come from nature, are renewable and degradable, making full use of plant fibers is very important to protect the environment and reduce dependence on petroleum resources significance.
