A method of making an anti-collision beam

Abstract

The invention discloses a manufacturing method of an anti-collision beam, which comprises the following steps: S1: preparing a natural wood board; S2: cleaning the lignin and hemicellulose in the wood board to form a wood board with a plurality of pores; S3: removing the wood board Put into the shear thickening liquid, so that the shear thickening liquid penetrates into the interior of the wood board through each channel and adheres to the wood board; S4: compact the wood board; S5: set a sealing layer on the end face of the wood board to seal the end. In the invention, the shear thickening liquid is filled in the wooden board to form an anti-collision beam. The anti-collision beam of the invention can fully absorb the energy generated by the collision, improve the safety performance of the vehicle, and effectively reduce the damage caused by the collision to the personnel, which belongs to the automobile anti-collision. The technical field of structure.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision structures, in particular to a manufacturing method of an anti-collision beam. Background technique [0002] Existing anti-collision beams are all designed from high-strength steel, generally designed as hollow metal structures to absorb stronger impact, but the higher density of metal is not conducive to the lightweight of the car, and the hollow structure can only resist One-time impact has no good effect on multiple or multi-stage impacts, and metal corrosion protection and disposal are extremely unenvironmental. Surface treatment during use or subsequent treatment after scrapping requires a lot of manpower and material resources, which is not in line with the development of green and sustainable automobiles. requirements. Existing wood panels are generally used in building walls, ceilings or car door panels, floors, etc. Although there are various wood panels with different ...

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
