Abstract

The invention discloses a preparation method of a thermoplastic composite material plate with a structural part. The preparation method comprises the following steps: the thermoplastic composite material plate (1) is taken; then, a forming line (2) is punched in the thermoplastic composite material plate (1); the thermoplastic composite material plate (1) punched with the forming line (2) is put in an injection molding machine mold (3), and the forming line (2) is positioned below a plastic injecting port of the injection molding machine mold (3); and high-temperature and high-pressure thermoplastic plastic is injected from the plastic injecting port (4) of the injection molding machine mold (3), the thermoplastic plastic impacts the position of the forming line (2), and the high-temperature and high-pressure thermoplastic plastic is partially fused with the thermoplastic composite material plate (1) downwards bent perpendicularly to form the thermoplastic composite material plate with the structural part. The preparation method is reasonable in process design, convenient to operate, high in yield, high in production efficiency and low in cost; and the prepared thermoplastic composite material plate with the structural part is high in strength, not easy to break and long in service life.

Description

technical field [0001] The invention relates to a preparation method of a fiber material panel structural part, in particular to a preparation method of a thermoplastic composite material plate with a structural part. Background technique [0002] With the rapid development of my country's economy, various electrical appliances, electronic products, motor vehicles and aerospace equipment have developed rapidly, and people are gradually pursuing high-quality life. The equipment shells of these products generally require strong hardness, strong impact resistance, and durability Heat and corrosion resistance properties. [0003] As in the prior art, the method used to make thermoplastic composite sheets with buckles, screw columns or rib structural parts is to use the compatibility of the thermoplastic resin of the thermoplastic composite sheet and the injected thermoplastic resin to make the thermoplastic composite The panels are connected to the structural members. This prep...
