Problems solved by technology

[0005] At present, FRP is widely used in various fields, but when making FRP frames, due to long-term stress, mechanical fatigue damage is prone to occur and affect the quality, especially when the pressure at the corners is obvious, this phenomenon will aggravate the frame. deformation or even damage

Embodiment 1

[0045] see Figure 1-2 , a method for preparing a bridging type strong corner point FRP frame, comprising the following steps:

[0046] S1. Weigh the resin for FRP profiles with a mass content of 25% and the glass fiber with a mass content of 75%, and prepare corresponding molds;

[0047] S2. Take four two-way bridging rods of appropriate size and place them at the four corners of the plastic groove in the mold respectively, and preliminarily shape them;

[0048] S3. Stir and mix the resin and glass fiber to obtain the rubber material. After mixing evenly, inject the rubber material into the glue groove in the mold, and flow along the glue groove for no less than three cycles;

[0049] S4. Wait for enough glass fibers to be adsorbed on the two-way bridging rods, and at the same time, no obvious air bubbles are generated. Immediately set the temperature of the pultrusion molding machine to 80°C, and cool naturally after pulling out the profile;

[0050] S5. After surface trea...

Abstract

The invention discloses a method for preparing a bridging-type strong-corner FRP frame, which belongs to the technical field of FRP processing, and can realize pre-embedding two-way bridging rods at four corners, and then force the glass fibers to circulate, and some of them have been specially treated Magnetic fibers, guided by the self-grafting pores on the two-way bridging rod, actively approach and pierce into it, releasing the pre-set filler. On the one hand, the inorganic filler is directly and evenly released to the corner area to match the glass fiber. On the other hand, the released self-heating material reacts with oxygen to generate a large amount of heat, and directly heats and solidifies the rubber at the corner from the inside to improve the molding effect. On the premise of controlling the cost of raw materials, the corner of the frame Concentrated strengthening is carried out to greatly improve the strength and quality of the FRP frame.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic processing, in particular to a method for preparing a bridging type strong corner glass fiber reinforced plastic frame. Background technique [0002] Fiberglass reinforced plastic (FRP) is also known as GFRP, namely fiber reinforced plastics, generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as reinforced plastics, called glass fiber Reinforced plastic, or FRP, is different from tempered glass. [0003] Due to the different types of resins used, there are polyester FRP, epoxy FRP, and phenolic FRP. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling, corrosion resistance. It can replace steel to manufacture machine parts, automobiles, ship shells, etc. [0004] The scientific name of FRP is fiber reinforced plastic, commonly known as FRP, that is, fi...
