Fiber-reinforced plastic, air rectification cover for elevator and process for manufacturing fiber-reinforced plastic

The invention relates to a fiber-reinforced plastic, an air rectification cover for an elevator and a process of manufacturing the fiber-reinforced plastic. The fiber-reinforced plastic (1) is provided with: a first fiber -reinforced plastic layer (2) that comprises a first fiber fabric (21) and a resin (22) with which the first fiber fabric (21) has been impregnated; a resin flow layer (3) that comprises inner media (31) and a resin (32) and that is superposed on the first fiber-reinforced plastic layer (2); a second fiber-reinforced plastic layer (4) that comprises a second fiber fabric (41) and a resin (42) with which the second fiber fabric (41) has been impregnated and that is superposed on the resin flow layer (3) so as to make the resin flow layer (3) disposed between the first fiber-reinforced plastic layer (2) and the second fiber -reinforced plastic layer (4); and an inorganic filler layer (5) that comprises an inorganic filler (51) having particle diameters of 20 to 50mum and a resin (52) and that is superposed on the second fiber-reinforced plastic layer (4) so as to make the second fiber-reinforced plastic layer (4) disposed between the inorganic filler layer (5) and the resin flow layer (3). The resins (22), (32), (42) and (52) are composed of the same composition, and have been formed integrally with each other.
