Abstract

The invention relates to a rigid reinforced automobile bottom protection plate and a production method thereof. The rigid reinforced automobile bottom protection plate is of a structure with five layers, namely, the polypropylene resin layer, the glass fiber mat layer, the polypropylene resin layer, the glass fiber mat layer and the polypropylene resin layer from top to bottom in sequence. The production method comprises the steps of heating the polypropylene resin layers and the glass fiber mat layers in a drying oven, laying and locating the polypropylene resin layers and the glass fiber mat layers in a closed forming mold, starting a forming press and carrying out pressing formation. The production steps of the rigid reinforced automobile bottom protection plate are simple, the produced automobile bottom protection plate is light in weight and high in strength, the weight of finished automobile equipment is greatly lowered, the rigidity of the automobile bottom protection plate is high, the automobile bottom protection plate will not be broken or droop, and the whole production process is free of hazardous substances and is friendly to environment.

Description

technical field [0001] The invention relates to a production method of a rigidity-enhanced automobile bottom guard plate, which belongs to the technical field of production of automobile exterior trim parts. Background technique [0002] The car bottom guard plate assembly is generally installed under the car chassis and directly faces the road surface; it is mainly used to protect the car chassis and related accessories during driving, and prevent the sewage, stone splashing on the road surface, and uneven road surface from dragging the bottom of the car chassis and other related problems. The influence of accessories; and through its good state stability and weather aging resistance, it can effectively protect and reduce the corrosion and impact of the chassis and related accessories, and play a role in blocking the influence of climate and geographical environment. In the era of increasingly pursuing high safety, environmental protection, energy saving, lightweight, and p...
