Another example is that the Chinese invention patent with the authorized notification number CN104393200B discloses a battery box made of composite materials. There is a reflective layer and a heat insulating layer in the space. The reflective layer is set close to the outer wall and is made of aluminum foil; the surface of the inner wall away from the clamping space forms a heating layer, which is made of heat-conducting copper foil (or graphite, or graphene) plus foaming material. Composition; the aluminum foil and copper foil set in the battery box can play the role of electromagnetic shielding, but the laying process of the box body is many and complicated

Abstract

The invention relates to a power battery box body, a preparation method thereof and a fiber reinforced composite material and belongs to the technical field of a power battery box body. The power battery box body of the present invention is mainly made of the following raw materials including, by weight, 40 to 65 parts of polymer base materials, 30 to 70 parts of reinforced fibers, 35 to 45 partsof flame retardants, 5 to 10 parts of lubricants, and 1 to 2 parts of fillers, and the reinforced fibers are metallized fibers or metallized fiber fabric. The power battery box body of the invention can be formed in one molding, the production process can be simplified, the cost is low, the yield is high, the power battery box body has a good electromagnetic shielding effect, a heavy metal plate or metal foil is not needed, and the power battery box body does not fail due to the vibration of a vehicle body. In addition, the power battery box body has the advantages of small weight, high strength, good insulation, corrosion resistance and high safety.

Description

technical field [0001] The invention relates to a power battery case, a preparation method thereof, and a fiber reinforced composite material, belonging to the technical field of power battery cases. Background technique [0002] In recent years, the environmental protection situation has become more and more serious. The state's subsidies for new energy vehicles and the limited number of traditional fuel vehicles due to environmental protection have made people more and more fond of new energy vehicles, especially pure electric vehicles. [0003] The power battery is a key component of a pure electric vehicle. At present, the most used materials for its box body are high-strength steel plates and aluminum plates. However, in order to meet the needs of power batteries for weight reduction, cost reduction, and anti-corrosion, some car companies have begun to use fiber reinforcement. Non-metallic materials such as composite materials or engineering plastics are used to make ba...
