Abstract

The invention relates to the field of composite materials, in particular to glass fiber reinforced plastic processing technology. The following technical scheme adopted in the invention is that: the glass fiber reinforced plastic processing technology mainly comprises the following steps of: spraying an unsaturated polyester gel coat on a die; gelling the unsaturated polyester gel coat at normal temperature; laying a resin glass fiber layer on the unsaturated polyester gel coat; wrapping the outer part of the resin glass fiber layer with nylon cloth and flatly compacting; curing and molding at a high temperature; and cooling at normal temperature after the curing and forming, and uncovering the nylon cloth. Through the technical scheme, a glass fiber reinforced plastic product can solve the surface quality problem at one time during machine shaping, later grinding and repairing are not needed, the production cost and pollution to air are reduced.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a glass fiber reinforced plastic processing technology. Background technique [0002] FRP is a kind of composite material, because of its unique performance advantages, it has been widely used in aerospace, railway, decorative construction and other industries. [0003] At present, during the processing of single-sided formed FRP products in my country, the glass fibers will be exposed on the surface, so the surface needs to be polished and repaired after forming. This requires related staffing, processing equipment and venues, energy consumption, and most seriously, the glass fiber powder scattered during the cutting and grinding process will cause serious air pollution. Contents of the invention [0004] The object of the present invention is to provide a glass fiber reinforced plastic processing technology without grinding and repairing procedures. [0005] In order to a...
