Problems solved by technology

However, the equipment composed of steel components is very bulky, which is contrary to the purpose of assisting in the handling of heavy objects, and its mechanical properties are increasingly difficult to meet the requirements of higher strength
At the same time, steel materials are not suitable for handling materials for electrostatic sensitive equipment
In addition, insulators tend to generate static charges due to friction in dry air, which will cause great harm to processing and use. Preventing static damage is very important for handling static-sensitive equipment.

Description

technical field [0001] The invention belongs to the technical field of load-bearing materials, and in particular relates to a preparation method of a novel load-bearing composite material. Background technique [0002] Existing handling equipment (such as fork plates, forklift frames, truck frames, and brackets) is mainly composed of steel components, and the manufacturing process is cumbersome and complicated. It mainly uses the rigidity of raw materials and the reasonable structural force distribution of components to achieve Auxiliary handling purposes. However, the equipment composed of steel components is very cumbersome, which is contrary to the purpose of assisting in the transportation of heavy objects, and its mechanical properties are increasingly difficult to meet the requirements of higher strength. At the same time, steel materials are not suitable for handling static-sensitive equipment. In addition, insulators tend to generate static charges due to friction ...
