Dual-layer protection shell with carbon fiber outer layer and rubber inner layer and manufacturing process thereof

Abstract

The invention provides a dual-layer protection shell with a carbon fiber outer layer and a rubber inner layer. The dual-layer protection shell comprises an inner layer that is made of a TPU rubber material; a cavity for accommodating a mobile phone is formed in the middle of the inner layer; and a mobile phone camera lens through hole is formed in the upper portion of the inner layer. An outer layer is arranged outside the inner layer and is provided with a carbon fiber sheet; and a through hole corresponding to the mobile phone camera lens through hole of the inner layer is formed in the upper portion of the outer layer. A first plastic component is arranged at the through hole portion of the outer layer; a second plastic component is arranged at the lower portion of the outer layer; and a groove corresponding to the second plastic component is formed in the upper portion of the inner layer. The provided dual-layer protection shell has advantages of high strength and light weight and is consistent with the low-carbon and environment-friendly trend; the pattern and the appearance of the shell are beautiful; the technical content of the high-tech materials is high; and the high-molecular plastic material moulding process is used and various colors of the shell are realized. Moreover, the shell has the anti-radiation function; and the inner layer is made of the TPU rubber material, so that softness is realized. And the mobile phone dismounting and mounting become easy.

Description

technical field [0001] The invention relates to a protective case for a mobile phone, in particular to a double-layered protective case with an outer layer of carbon fiber and an inner layer of rubber and a manufacturing process thereof. Background technique [0002] Mobile phone is a common communication tool for people. Almost everyone owns it, and the market has a huge amount. Therefore, the protection of mobile phones is also very important. [0003] Carbon fiber (Carbrn Fiber) is a fibrous carbon material, which is stronger than steel, less dense than aluminum, more corrosion-resistant than stainless steel, and more resistant to high temperatures than heat-resistant steel. Molecular plastic raw materials are made by combining the difficult injection molding process with four materials and four colors with different textures. [0004] However, there is no dual-layer mobile phone case containing carbon fiber on the market. Contents of the invention [0005] In order t...
