Embodiment Construction

[0025] A soft, tough and impact-resistant composite material body, which is a body or an assembled combination formed by vulcanizing at high temperature together with multi-layer composite rubber, multi-layer soft wire or soft steel wire and skeleton spring or spring leaf. Multiple layers of bulletproof cloth are sandwiched in the composite rubber layer to make a car body or assembled combination with impact resistance and bulletproof functions.

[0026] The composite rubber is made of the following raw materials by weight: 100kg of natural rubber, 2kg of stearic acid, 4kg of zinc oxide, 1.5kg of sulfur, 48kg of carbon black N220, 1.5kg of accelerator MDB, 11g of antioxidant RD, and 2kg of paraffin wax , Fang Jin oil 7kg.

[0027] The soft silk thread can be woven fabric or various cord fabrics.

[0028] The soft toughness and impact-resistant composite material vehicle body is composed of 8% soft silk or soft steel wire, 20% spring or leaf spring, and 72% composite rubber. ...

Abstract

The invention discloses a flexible impact-resistant composite automobile body and a production process thereof. The automobile body is an automobile body or an assembled combination formed by subjecting multilayer composite rubber, multilayer soft silk sutures or soft steel wires and a framework spring or leaf spring to high-temperature vulcanization, as well as can be made into an automobile body or assembled combination with impact-resistant and bulletproof functions by means of embedding multilayer ballistic fabrics into multilayer composite rubber. By the aid of formulation optimization and process improvement, mechanical strength and impact resistance of the automobile body materials are enhanced effectively so as to improve mechanical property thereof. The machined automobile body is lightweight, high in mechanical strength, good in toughness and high in impact resistance, fragility and fatigability of traditional automobile bodies are avoided, and requirements on automobile securitization and light weight pursued by modern people are met safely.

Description

technical field [0001] The invention relates to a car body made of soft, ductile, impact-resistant composite material and a manufacturing process thereof, belonging to the technical field of car bodies. Background technique [0002] As an important part of the car structure, the car body plays a very important role in reducing the initial overall quality and improving the safety of the car. At present, there are many kinds of car bodies in the market, and the shapes are complex. The traditional car body materials are in a single state of thin metal plates, which have poor impact resistance and are easy to tear. It cannot adapt to people's pursuit of car safety and light weight. Require. In order to reduce the weight of the car body, improve the soft toughness and impact resistance of the car body, improve the safety of the car and prolong the service life, many manufacturers have made great efforts, especially the development of new materials for the car body has attracted ...
