Once-formed composite material board and notebook computer shell prepared from once-formed composite material board

Abstract

The invention provides a once-formed composite material board and a notebook computer shell prepared from the once-formed composite material board. The once-formed composite material board comprises acentral woven fabric layer, inner PC film layers, intermittent woven fabric layers and outer PC film layers, wherein the inner PC film layers are located on two sides of the central woven fabric layer, the intermittent woven fabric layers are located on two sides of the inner PC film layers, and the outer PC film layers are located on two sides of the intermittent woven fabric layers; and the smelting points of the outer PC film layers are lower than the smelting points of the inner PC film layers. The notebook computer shell is prepared from the once-formed composite material board. By virtue of the laminated design and the material design, the notebook computer shell is prepared from the composite material board. Compared with a composite material computer shell in the past, the notebook computer shell provided according to the invention has the advantages that the shell can be endowed with different colors by selecting the colors of the PC films, is once formed and does not need tobe secondarily coated, so that the production efficiency of the composite material notebook computer shell can be improved, the equipment input and the pollution of the coating process caused due tothe coating can be avoided, and the positive social benefit is realized.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to a one-time molding composite material board and a notebook computer shell made from the board. Background technique [0002] At present, notebook computer shells can be made of many materials, including aluminum-magnesium alloys, plastics, composite materials, etc. Each material has its own advantages and disadvantages. For example, the main element of aluminum-magnesium alloy aluminum plate is aluminum, and a small amount of magnesium or other metal materials are added to enhance its hardness. The advantages are its low density, high specific strength, good heat dissipation performance, small elastic modulus, good rigidity, and long-term It is not easy to be deformed, strong shock resistance, anti-electromagnetic interference, good electromagnetic shielding, bright and beautiful color, corrosion resistance, and can maintain the appearance quality for a long time. It is an environment...

AI Technical Summary

Problems solved by technology

For example, the main element of aluminum-magnesium alloy aluminum plate is aluminum, and then a small amount of magnesium or other metal materials are added to strengthen its hardness. It is not easy to deform, has strong shock resistance, good electromagnetic interference resistance, good electromagnetic shielding, bright and beautiful color, corrosion resistance, and can maintain the appearance quality for a long time. It is an environmentally friendly material, and its waste can be recycled; the disadvantage is that its processing and assembly process is difficult. , the yield of die-casting parts is low, and the waste of slag collection bag, runner and gating system is more, and the quality is poor

Plastic has light weight, chemical stability, no rust, good impact resistance, good transparency and wear resistance, good insulation, low thermal conductivity, good general formability and coloring, and low processing cost etc., but most plastics have disadvantages such as poor heat resistance, high thermal expansion rate, easy combustion, poor dimensional stability, easy deformation, poor low temperature resistance, brittleness at low temperature, and easy aging.

[0003] With the development of composite material technology, more and more composite materials are used in notebook computer casings, such as carbon fiber composite materials, but the color of the products produced is relatively monotonous and single, and it needs to be obtained through cumbersome spraying procedures.
