NOVELTY - A fiber-reinforced plastic (1) comprises a fiber-reinforced plastic layer (2) containing fiber fabric (21) and a resin (22) with which the fiber fabric (21) is impregnated, a resin flow layer (3) containing inner media (31) and a resin (32), a fiber-reinforced plastic layer (4) containing fiber fabric (41) and a resin (42), and an inorganic filler layer (5) containing an inorganic filler (51) and a resin (52) and is superposed on the fiber-reinforced plastic layer (4) so as to make the fiber-reinforced plastic layer (4) arranged between inorganic filler layer and resin flow layer.    USE - Fiber-reinforced plastic is used for forming wind adjustment cover (claimed) for elevators. Can also be used for forming blade of windmill, aircraft components, and ship components.    ADVANTAGE - The fiber-reinforced plastic is manufactured efficiently with excellent productivity.    DETAILED DESCRIPTION - A fiber-reinforced plastic comprises a fiber-reinforced plastic layer (2) containing fiber fabric (21) and a resin (22) with which the fiber fabric (21) is impregnated, a resin flow layer containing inner media and a resin (32) and superposed on the fiber-reinforced plastic layer, a fiber-reinforced plastic layer (4) containing fiber fabric (41) and a resin (42) with which the fiber fabric (41) is impregnated and superposed on the resin flow layer so as to make the resin flow layer arranged between the fiber-reinforced plastic layer (2) and the fiber-reinforced plastic layer (4), and an inorganic filler layer containing an inorganic filler having particle diameters of 20-50 mu m and a resin (52) and is superposed on the fiber-reinforced plastic layer (4) so as to make the fiber-reinforced plastic layer (4) arranged between the inorganic filler layer and the resin flow layer. The resins (22), (32), (42) and (52) are composed of the similar composition, and formed integrally with each other. An INDEPENDENT CLAIM is included for manufacture of fiber-reinforced plastic.
