Abstract
The invention relates to a fiber reinforced polymer composite material and a preparation method thereof, wherein the fiber reinforced polymer composite material comprises a polymeric resin matrix in a continuous phase, and chemical fiber fabric and reinforced fibers dispersed in the polymeric resin matrix, and the chemical fiber fabric covers the reinforced fibers so as to avoid exposure of the reinforced fibers to an outside surface of the composite material. The invention reduces or even avoids exposure of the reinforced fibers of the fiber reinforced polymer composite material, and can be used for manufacturing cable bridges, frames of doors, windows and curtain walls, etc. The method for preparing the fiber reinforced polymer composite material of the invention effectively improves the performance of the composite material and also reduces the cost of surface treatment and increases production efficiency.
