Preparing method of high-strength fiber composite material

The invention relates to a preparing method of a high-strength fiber composite material. The preparing method includes the following steps of cutting, rolling, performing, forming and demolding. Fiber composite material cloth in use is at least one of carbon fiber composite material cloth and glass fiber composite material cloth, and a polymeric film in use comprises a high-temperature thermocuring resin film and a high-viscosity polymer composite material. The strength of a product can be effectively promoted after the prepared fiber composite material is formed. The forming process is easy to operate, high in efficiency and low in requirement for the technology of operators, and common personal can implement operation.
