Embodiment Construction

[0031] 1. About materials

[0032] The best of its components and weight percentages are:

[0033] High Performance Resin 35%

[0034] Chopped Fiber 10%

[0035] Fiber Cloth 55%.

[0036] Described high-performance resin selects vinyl epoxy resin for use;

[0037] The chopped fibers are selected from carbon fibers, and the fiber length is 0.5-2cm;

[0038] The fiber cloth is selected from alkali-free glass fiber cloth, basalt fiber cloth or carbon fiber cloth.

[0039] 2. About the method

[0040] Step ②:

[0041] Medium temperature curing temperature: 150-170 degrees Celsius, for vinyl epoxy resin and other medium temperature curing epoxy resin;

[0042] High temperature curing temperature: 220-250 degrees Celsius, for high temperature curing resin.

[0043] The layer-by-layer laying means that the stressed material is designed according to 4-5 layers of fiber cloth;

[0044] Typical carbon fiber cloth weight is 450 g / m 2 , 300 g / m 2 or 200 g / m 2 .

Abstract

The invention discloses a high-strength FRP (Fiber Reinforced Polymer) material and a production method and an application thereof, which relate to an FRP material. The high-strength FRP material is produced by compounding high-performance resin and fibers, which comprises the following components by weight percent: 20 to 40 percent of high performance resin, 10 to 20 percent of chopped fibers and 50 to 60 percent of fiber cloth. The production method comprises the following steps: (1) the high performance resin is blended and uniformly mixed with the chopped fibers to obtain a curing agent; (2) the fiber cloth is gradually laid inside a mould layer by layer, is gradually and adequately steeped by the curing agent layer by layer, is arranged inside a vacuum tank with the vacuum degree of 0.098 MPa or more and is cured and formed under the condition with the temperature of 150 to 250 DEG C so as to obtain a high-strength FRP material. The high-strength FRP material is free from being rusted, has no magnetism, good electromagnetic insulation performance and light weight, can reduce the structural weight and can reduce the cost.

Description

technical field [0001] The present invention relates to an FRP (Fiber Reinforced Polymer, fiber-reinforced high molecular polymer) material, in particular to a high-strength FRP material and its manufacturing method and application. Background technique [0002] The Achilles heel of steel as a structural material is as follows: First, corrosion changes the chemical composition of the structural material, resulting in the reduction or even loss of the original mechanical properties of the steel, so the corrosion problem seriously affects the durability of the structure; secondly, with the development of economy and science, People have more and higher demand for building materials, and steel beams and bars (steel wires) are difficult to meet the requirements; third, steel is a consumable resource and is not renewable. From the perspective of human long-term development, FRP materials should be used instead of steel for construction Materials are an inevitable trend. [0003]...
