Embodiment 1

[0093] The fiber is impregnated by using the impregnation system for the fiber reinforced composite material provided in the embodiment of the present application. Wherein, the impregnation system does not include mechanical vibration equipment, and during the process of pouring the resin matrix material, the pressure in the storage tank is about 0.2Mpa. Set the amount of glue supply (that is, the amount of resin matrix material) to 22kg / min, the production speed to 0.8m / min, the mass ratio of fiber to resin matrix material to 1:1, and the size of the cavity of the molding equipment to be 260×260(mm) , 9600Tex glass fiber consumption is 2140 bundles, and the production molding section size is 260×260 (mm) 760kg / m 3 synthetic sleepers. According to the standard CJ-T399-2012-polyurethane foam synthetic sleeper, the performance of the synthetic sleeper is tested, and the main test results are shown in Table 1.

Abstract

The invention discloses a fibre-reinforced composite material impregnation system. The fibre-reinforced composite material soaking system comprises dosing equipment, mixing equipment, a storage tank and a resin fibre mixing mould, wherein the dosing equipment supplies a resin matrix material; the mixing equipment is connected with the dosing equipment, and is configured to uniformly mix the resinmatrix material from the dosing equipment; the storage tank is connected with the mixing equipment; a supercharge hole is formed in the storage tank; a plurality of supply holes are formed below the storage tank; a plurality of glue injecting holes of the resin fibre mixing mould are arranged below the material supply holes in a one-to-one correspondence mode. According to the soaking system, themechanization degree is high, efficient and stable production efficiency is achieved, and the problems that fibre and resin matrix are impregnated unevenly as multiple persons alternately rub in turn,the cost is high, the dimension of a formed product is limited and the like are solved.

Description

technical field [0001] This application relates to but not limited to the molding technology of fiber-reinforced composite materials, especially relates to but not limited to an impregnation system of fiber-reinforced composite materials and its resin fiber mixing mold and application. Background technique [0002] In fiber-reinforced polyurethane foam molding technology, in order to effectively reinforce foamed polyurethane foam with multiple bundles of continuous long fibers, sufficient and uniform impregnation between the two is required. At present, the impregnation section in the molding process of fiber reinforced polyurethane foam adopts the method of alternate kneading by multiple people in shifts. The impregnation effect of this method is unstable, especially during long-term production, the fatigue of the workers increases, the concentration decreases, and the impregnation effect will decrease accordingly. In addition, the polyurethane resin will solidify after fo...
