PROBLEM TO BE SOLVED: To obtain a fiber-reinforced plastic by crosslinking a polytetrafluoroethylene of a polytetrafluoroethylene composite with an ionizing radiation wherein the composite is obtained by using carbon fiber, glass fiber, silicon carbide fiber, silicon nitride fiber, PBO fiber, aramid fiber, or the like as a reinforcing fiber. SOLUTION: The fiber-reinforced crosslinked polytetrafluoroethylene is obtained by crosslinking a preform of the fiber-reinforced polytetrafluoroethylene by irradiating the ionizing radiation thereto and then laminating the preform under a condition of heating and pressurizing at 100-400 deg.C. |
