Description

technical field [0001] The invention belongs to the technical field of computer shell preparation, and in particular relates to a composite material for a notebook computer shell. Background technique [0002] With the rapid development of the notebook computer industry, the notebook computer casing is also developing in the direction of high strength, high rigidity and light weight. At present, most of the plastic casing notebook computers on the market are made of PC / ABS engineering plastic alloy. This material not only has the excellent heat and weather resistance, dimensional stability and impact resistance of PC resin, but also has the excellent processing fluidity of ABS resin. However, with the development of notebook computers, the comprehensive mechanical properties of PC / ABS alloys are not ideal due to factors such as protecting fragile electronic components and strengthening the strength of the overall structure, resulting in unsatisfactory thickness and weight o...
