A method for forming a 3D curved surface of a thin film composite glass fiber board

Abstract

The invention belongs to the field of 3D curved surface manufacturing, and particularly relates to a thin-film glass fiber board 3D curved surface forming method. Thin film PET, glass fiber cloth and modified epoxy resin are adhered and then are subjected to bent forming by virtue of high-pressure forming; and a plurality of board products can be simultaneously bent and formed by virtue of high-pressure forming. The thin-film composite glass fiber board 3D curved surface forming method has the beneficial effects that: firstly, compared with a previous common adhering technology, the thin-film composite glass fiber board 3D curved surface technology can achieve 3D curved surface effect; secondly, compared with a previous common hot-press forming technology, the thin-film composite glass fiber board 3D curved surface technology enables the glass fiber boards to be prevented from being cracked in a heated process, and can sufficiently achieve requirements of an original design; and thirdly, compared with a previous common board product, the thin-film glass fiber boards subjected to the thin-film composite glass fiber board 3D curved surface technology have higher mechanical strength, realize thinner structural design requirements, and even replace a conventional 3D glass product.

Description

technical field [0001] The invention belongs to the field of 3D curved surface production, and in particular relates to a method for forming a 3D curved surface of a film composite glass fiber board. Background technique [0002] With the continuous development of the appearance structural parts of modern consumer electronics products in the direction of lightness and thinness, and the structural strength requirements have not been reduced, but with the aesthetic and ergonomic requirements of consumers for the appearance, there is an urgent need for thin film composite glass fiber board structural parts. bending. However, the mechanical strength of traditional composite sheet 2D and 3D products is low, the thickness of the product structure is relatively thick, the price of glass products is too high and fragile, and cannot meet the needs of popularization, and the ordinary flat glass fiber sheet cannot meet the design requirements, and the glass fiber sheet Poor elongation...

Problems solved by technology

However, the mechanical strength of traditional composite sheet 2D and 3D products is low, the thickness of the product structure is relatively thick, the price of glass products is too high and fragile, and cannot meet the needs of popularization, and the ordinary flat glass fiber sheet cannot meet the design requirements, and the glass fiber sheet Poor elongation and high mechanical strength; traditional hot bending technology will lead to insufficient deformation of the product and fail to meet the design requirements, resulting in serious deformation of the product, insufficient bending of the shape, failure to reach the original design concept of the product, and even lead to Problems such as inability to assemble and structural interference; there is also the risk of deformation and springback of hidden structural parts, which may cause problems such as falling of electronic products during long-term use, which seriously affects the use of consumers

[0003] Moreover, the design of traditional 3D curved surface structural parts cannot meet the needs of communication electronics consumer housings and home appliance structural parts that are becoming lighter, thinner and require structural strength.
