Embodiment

[0042] Such as figure 1 , a reinforced FRP 100, comprising: a gel coat layer 3 on the surface, a glass fiber layer 2 in the middle, and a rib layer 1 on the bottom.

[0043] For ease of description, this embodiment assumes that it is a cuboid with a surface area of ​​40mm*50mm and a thickness of about 10mm. This set of data is only for the convenience of describing the present invention, and the present invention is not limited by the data.

[0044] A fiberglass layer 2 is laid on a gel coat layer 3 comprising several layers of resin-impregnated fiberglass. In this embodiment, the glass fiber layer 2 includes five layers of glass fibers.

[0045] Such as figure 2 , The reinforcing rib layer 1 is laid on the glass fiber layer 2, which includes several reinforcing ribs 11 soaked with resin, and several layers of glass fibers 12 soaked with resin for wrapping the reinforcing ribs. Several reinforcing ribs are distributed and arranged in any direction. In this embodiment, th...

Abstract

The invention discloses a method for manufacturing reinforced FRP, which includes the following steps: S1: making a mold; S2: making reinforced FRP according to the mold, the reinforced FRP includes: a gel coat layer on the surface and a glass fiber layer in the middle , the reinforcement layer positioned at the bottom surface; the glass fiber layer is laid on the gel coat layer, which includes several layers of glass fibers; the reinforcement layer is laid on the glass fiber layer, which includes several reinforcement ribs, and is used for wrapping Several layers of glass fiber for reinforcing ribs; S3: post-processing of reinforced FRP; among them, S2 further includes: S21: spray gel coat on the mold, and wait for it to cure to complete the production of the gel coat layer; S22: in the gel coat layer Laying several layers of glass fiber completely soaked by resin on top, and waiting for it to be solidified and formed, to complete the production of glass fiber layer; S23: laying a reinforcement layer on the basis of S22. Compared with the prior art, the enhanced FRP produced by the invention is not easily deformed, has strong toughness and excellent performance.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a reinforced glass fiber reinforced plastic and a manufacturing method thereof. [0002] Background technique [0003] Fiberglass reinforced plastic (FRP), also known as GRP, is fiber-reinforced plastic. It is a composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn) as a reinforcing material and synthetic resin as a basic material. Due to these unique performance advantages of FRP, it has been widely used in aerospace, railway, decorative construction and other industries. [0004] Although FRP has many advantages such as light and hard, non-conductive, high mechanical strength, less recycling, corrosion resistance, etc., it also has some defects, such as easy deformation and aging. [0005] At present, the common FRP manufacturing process can be roughly divided into the following steps: 1. Make a mold and apply a release agent on the mold; ...
