Manufacturing method of anti-collision beam

Abstract

The invention discloses a manufacturing method of an anti-collision beam. The manufacturing method comprises the following steps that S1, a natural wood board is prepared; S2, lignin and hemicellulose in the wood board are cleaned to form the wood board with a plurality of pore channels; S3, the wood board is put into shear thickening liquid, and the shear thickening liquid penetrates through all the pore channels to be immersed into the wood board and attached to the wood board; S4, the wood board is compacted; and S5, a sealing layer is arranged on the end face of the wood board for end sealing. According to the manufacturing method, the wood board is filled with the shear thickening liquid to form the anti-collision beam, the anti-collision beam can fully absorb energy generated by collision, the safety performance of a vehicle is improved, and the damage to personnel caused by collision is effectively reduced, and the anti-collision beam belongs to the technical field of automobile anti-collision structures.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision structures, in particular to a method for manufacturing an anti-collision beam. Background technique [0002] Existing anti-collision beams are all designed from high-strength steel, generally designed as a hollow metal structure to absorb stronger impact, but the high density of metal is not conducive to the lightweight of the car, and the hollow structure can only resist One-time impact does not have a good effect on multiple or multi-stage impacts, and metal anti-corrosion and waste disposal are extremely unenvironmental. Surface treatment during use or follow-up treatment after scrapping requires a lot of manpower and material resources, which is not in line with the green and sustainable development of automobiles. requirements. Existing planks are generally used in many aspects such as building walls, ceilings or car door panels, floors, etc., although there are various pl...

AI Technical Summary

Problems solved by technology

However, for the high-strength boards required in some special areas, due to the influence of the structural strength and internal defects of the board itself, the strength and impact resistance are usually not high, which cannot meet the needs of use, and only a small number of trees have high-strength and anti-corrosion properties. The use value of the impact, so the use of ordinary wood as the anti-collision beam is difficult to match the anti-collision beam made of metal
