Abstract

The invention discloses a continuous fiber bundle reinforced composite material as well as a preparation method and application thereof. The continuous fiber bundle reinforced composite material comprises a strip layer, an upper film layer and a lower film layer, the upper film layer and the lower film layer are arranged on the upper side and the lower side of the strip layer, the strip layer contains continuous fiber bundles, and the upper film layer and the lower film layer do not contain the continuous fiber bundles. According to the continuous fiber bundle reinforced composite material, an impregnating compound does not need to be added, the compatibility between the reinforced material and matrix resin is good, the problem of poor interface bonding does not exist, and good weather resistance and aging resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a continuous fiber bundle reinforced composite material and its preparation method and application. Background technique [0002] Fiber-reinforced composite material is a composite material made of polymer as a matrix and fiber materials such as fiber bundles as reinforcement materials. engineering materials. [0003] However, the compatibility between the glass fiber and the resin matrix in the prior art is relatively poor, the interface is not well bonded, and defects are easily formed. When the strip is used outdoors, it is easy to cause the base material to crack due to UV aging, etc., and the performance lost. For this reason, the surface properties of the glass fiber can be changed by using the sizing agent, the compatibility with the resin matrix can be enhanced, and the performance of the composite material can be improved to a certain extent. In the proces...
