Fiber reinforced composite material and manufacturing method thereof
One embodiment of the present invention provides a method for manufacturing a fiber-reinforced composite material. The method for manufacturing a fiber-reinforced composite material comprises: a first step (S100) of causing carbon fibers or silicon carbide fibers to be impregnated in a polymer solution and curing the polymer solution to form a fiber molded body; a second step (S200) of increasing the temperature of the fiber molded body from the room temperature to a first temperature in an air atmosphere while performing first carbonization heat treatment; and a third step (S300) of performing second carbonization heat treatment while increasing the temperature of the first carbonized heat-treated fiber molded body from the first temperature to a second temperature in an inert gas atmosphere. According to one embodiment of the present invention, the method for manufacturing a fiber-reinforced composite material can improve the carbonization yield and utilize various polymers.
