Strong-combined composite material plate

Abstract

The invention discloses a strong-combined composite material plate. The strong-combined composite material plate comprises a composite material plate (1) and a thermoplastic material frame (2) connected to the periphery of the composite material plate (1) in an injection molding mode; the end surface of the composite material plate (1) is cut to form a concave-convex surface, and the concave-convex surface of the end surface is filled with a thermoplastic material and then is combined with the composite material plate (1); the composite material plate (1) or the thermoplastic material frame (2) is provided with sawtooth grooves, and the composite material plate (1) and the thermoplastic material frame (2) are connected in a meshed mode through the sawtooth grooves; the shapes of two adjacent sawtooth grooves in the composite material plate (1) or the thermoplastic material frame (2) are the same or different; and one or more grooves with the opening size larger than that of the openings of the sawtooth grooves are formed in the sawtooth groove. The strong-combined composite material plate has a reasonable structural design, and has the advantages of high bonding strength, firm structure, simple connecting process and good environmental protection property due to the fact that the one or more sawtooth-shaped grooves are adopted for meshed connection.

Description

technical field

[0001] The invention relates to a fiber material panel, in particular to a firmly bonded composite material plate. Background technique

[0002] With the rapid development of my country's economy, various household appliances, electronic products, motor vehicles and aerospace equipment have been developed rapidly. The shells of these products generally require strong hardness, strong impact resistance, heat resistance and corrosion resistance.

[0003] For example, in the prior art, such as a computer casing, the use of a plastic casing has disadvantages such as low strength and weak impact resistance. For example, a composite material casing such as carbon fiber is used, which is not only light in weight, but also high in strength and strong in impact resistance. Existing composite materials Splicing glue with the plastic shell is generally bonded by spraying glue, which has poor bonding force and weak bond. In addition, spraying glue has great environmental...
