New type automobile gasoline tank and forming method thereof

Abstract

The invention relates to a new type automobile gasoline tank and a forming method thereof. the new type automobile gasoline tank comprises an upper part of the gasoline tank and a lower part of the gasoline tank which are connected in a butting manner, wherein the upper part of the gasoline tank is provided with an oil inlet; the upper part of the gasoline tank and the lower part of the gasoline tank are made of a glass fiber reinforced plastic material; a joint adopts a glass fiber reinforced plastic hand lay-up process, and adopts 400g / m<2> of glass fiber woven roving to perform hand lay-up connection in a sealing manner. The forming method comprises the following steps that (1) an upper die of the gasoline tank and a lower die of the gasoline tank are sprayed with gel coat for curing; (2) a layer of 1100g / m<2> of combination mat and a layer of 1080g / m<2> of sandwich felt are respectively laid at the interiors of the upper die of the gasoline tank and the lower die of the gasoline tank in sequence after the gel coat is cured; (3) UPR (unsaturated polyester resin) is introduced into the combination mat and the sandwich felt by utilizing a vacuum bag molding process; (4) demoulding is respectively performed after curing to obtain split upper part of the gasoline tank and the lower part of the gasoline tank; (5) the upper part of the gasoline tank and the lower part of the gasoline tank are connected in a butting manner, and are connected in a sealing manner by adopting the 400g / m<2> of glass fiber woven roving through the hand lay-up process; (6) burrs polishing are performed.

Description

technical field [0001] The invention relates to a novel automobile fuel tank and a forming method thereof. Background technique [0002] Traditional automotive fuel tanks are mostly made of iron or engineering plastics. Iron fuel tanks are cheap but have potential safety hazards. When a car accident occurs, sparks will be generated to ignite gasoline due to collisions with the fuel tank, causing more serious consequences; engineering plastic fuel tanks are relatively expensive. High, and the cost of mold opening is high, and the cost is high. A low-cost fuel tank made of a new material that can avoid potential safety hazards needs to be developed urgently. Contents of the invention [0003] The invention provides a novel automobile fuel tank with low production cost and high safety factor in order to solve the technical problems existing in the known technology. [0004] The technical solution adopted by the present invention to solve the technical problems existing in th...
