Carbon glass fiber composite pultrusion plate and production process and production equipment thereof

Abstract

The invention discloses a carbon glass fiber composite pultrusion plate, which is formed by using carbon fibers and glass fibers to impregnate a resin material and then performing pultrusion, and a glass fiber layer wraps a carbon fiber layer. The invention also discloses a production process of the carbon glass fiber composite pultrusion plate. The production process comprises the following steps: (1) calculating the required use amounts of carbon fibers and glass fibers, (2) sequentially making the carbon fibers and the glass fibers penetrate through a yarn collecting plate and a layered yarn plate and then carrying out gum dipping treatment, (3) feeding the impregnated carbon fibers into a pre-forming mold, (4) feeding the glass fibers and the carbon fibers passing through the pre-forming mold into a forming mold together, and performing pultrusion to form a plate, and (5) curing, cooling, drawing and rolling the formed plate. The weight of the composite pultrusion plate is far lower than that of a pure glass fiber pultrusion plate, the composite pultrusion plate has excellent mechanical properties and strong performance designability, the strength and modulus of the composite pultrusion plate meet the material requirements of a large fan blade girder, the cost is low, and the composite pultrusion plate is beneficial to wide popularization and application.

Description

technical field [0001] The invention belongs to the technical field of composite material production, and in particular relates to a carbon-glass fiber composite pultrusion plate and its production process and production equipment. Background technique [0002] At present, the pultruded sheet products used in the fan blade girder are generally traditional glass fiber pultruded sheet and traditional carbon fiber pultruded sheet; the cost of traditional glass fiber pultruded sheet is slightly lower, but its weight is high and its mechanical properties are average. Its strength and rigidity are obviously insufficient; because the length of the blade is proportional to the power of the fan, the longer the blade, the larger the wind receiving area and the greater the power of the fan, so as the length of the blade increases, the quality of the blade will also increase. A large increase will lead to a large increase in load; therefore, the traditional glass fiber pultruded sheet c...

Problems solved by technology

[0002] At present, the pultruded sheet products used in the fan blade girder are generally traditional glass fiber pultruded sheet and traditional carbon fiber pultruded sheet; the cost of traditional glass fiber pultruded sheet is slightly lower, but its weight is high and its mechanical properties are average. Its strength and rigidity are obviously insufficient; because the length of the blade is proportional to the power of the fan, the longer the blade, the larger the wind receiving area and the greater the power of the fan, so as the length of the blade increases, the quality of the blade will also increase. A large increase, which will lead to a large increase in load; therefore, the traditional glass fiber pultrusion sheet does not meet the requirements as an ideal material for fan blade pultrusion sheet

Although the traditional carbon fiber pultrusion sheet is light in weight, its cost is high, and the carbon fiber resources used are relatively scarce, which is not suitable for the promotion and popularization of large quantities in the future; in addition, due to the high strength and modulus of carbon fiber, in a certain To a certain extent, the development of technology is limited, and the designability of performance is not strong
