Description
Technical Field
The utility model relates to a glass fiber product technical field especially relates to a reinforcement glass fiber fabric for preimpregnation material.
Background
Prepreg is a composite of a resin matrix and reinforcement made by impregnating continuous, chopped fibers or fabrics with the resin matrix under strictly controlled conditions, and is an intermediate material in the manufacture of composite materials.
Glass fiber fabrics are used as reinforcing materials for prepregs, and are used as structural materials for aircraft, automobiles, and the like, as materials for sports goods, and as materials for general industrial use because of their high specific strength and specific modulus.
In the manufacturing process of the glass fiber fabric, the performance design of the prepreg product can be realized by adjusting the gram weight of the fabric, the fiber orientation and the ply angle. In the prior patent publication of "a method for manufacturing a glass fiber check cloth prepreg", glass fiber check cloth is mainly used as a reinforcement of the prepreg. However, the glass fiber scrim is formed by vertically interweaving warp yarns and weft yarns, and the warp yarns are bent to some extent, so that the performance of the glass fiber is impaired to some extent, and finally the performance of the prepreg is reduced. In addition, the glass fiber plaid presents a phenomenon of 'one concave and one convex' on the surface of the fabric due to the interweaving structure of the yarns, which can cause uneven distribution of resin in the final prepreg. Finally, the glass fiber plaid has high stiffness, the fabric is hard, the shape following performance is poor, and the processing process of the prepreg is not facilitated.
In view of the above, it is a technical problem to be solved in the art to design and develop a reinforcement glass fiber fabric for prepreg, which has high surface flatness, good conformability, and excellent performance.
