A comb-loading mechanism for fibers on an FRP plate, comprising a feeding frame (1) for placing a fiber tray (2), a comb assembly provided downstream the feeding frame (1) and used for dividing fibers into a plurality of bundles, and a feeding roller (4) located downstream the comb assembly; the comb assembly comprises a comb frame (31) and a comb rod (33) mounted on a lower end face of a cross beam (32) of the comb frame (31) and extending downward, a loading assembly for arranging the fiber bundles on the feeding roller (4) is provided on a longitudinal beam (34) of the comb frame (31) and at a position lower than the comb rod (33). Said mechanism utilizes the loading assembly on the comb frame to lift the dropped fibers and enables the fibers to be uniformly distributed on the loading assembly, and the loading assembly drives the fibers to pass through the comb rod and then the fibers are arranged on the feeding roller.
Disclosed is an FRP composite board, comprising a filling layer and an FRP plate (1) adhered on one face or two faces of the filling layer, wherein the filling layer at least comprises one or more cement board layers (2), a surface of the cement board layer (2) is provided with multiple connection grooves (3) which are wider at the middle and narrower at both ends, and a side face of the FRP plate (1) that is attached to the cement board layer (2) is provided with connection ribs (4) matching the connection grooves (3). The composite board is strong and easy to clean.

A fiber feeding mechanism used for an FRP board, comprising a feeding rack (1) used for placing a fiber tray (2), a comb tooth assembly that is disposed downstream from the feeding rack (1) and that is used for dividing fibers into a plurality of bundles, and a feeding roller (4) located downstream from the comb tooth assembly; the comb tooth assembly comprises a comb tooth rack (31) and a comb tooth bar (33) that is mounted at a lower end surface of a horizontal beam (32) of the comb tooth rack (31) and that extends downward; a feeding assembly used for arranging fiber bundles on the feeding roller (4) is disposed at a position on a vertical beam (34) of the comb tooth rack (31) below the comb tooth bar (33), and an auxiliary pipe (310) extending toward the feeding roller (4) is disposed on the comb tooth bar (33); the feeding mechanism further comprises an air supply portion (313) used for introducing hot air in a heating furnace of an FRP board production line into the auxiliary pipe (310). Fibers are preheated using the hot air in an FRP board heating furnace to increase the bonding strength between the fibers and a resin and to ensure the stable conveyance of the fibers. Moreover, the hot air performing preheating for the feeding assembly may improve the viscosity of the feeding assembly, and ensure that the fibers may be evenly distributed on the feeding roller (4).
Disclosed is a fiber comb teeth anti-fall mechanism for a FRP plate, the mechanism comprising a feeding frame (1) for having a fiber material plate placed thereon, a comb teeth assembly (3) arranged downstream of the feeding frame (1) and used for dividing fibers into multiple bundles, and a feeding roller (4) located downstream of the comb teeth assembly (3), wherein the comb teeth assembly (3) comprises a comb teeth frame (31) and a comb teeth rod (33) which is mounted on a lower end face of a cross beam (32) of the comb teeth frame (31) and which extends downwards; and an auxiliary pipe (310) extending toward the feeding roller (4) is arranged on the comb teeth rod (33). The anti-fall mechanism further comprises an air supply portion (312) for supplying air to the auxiliary pipe (310). The mechanism slowly blows the fibers by means of the auxiliary pipe to ensure the stable conveying thereof, thus ensuring the stability of feeding a downstream cutting mechanism and the uniform arrangement of the fibers on the feeding roller.
Disclosed are an FRP board and a manufacturing method thereof, wherein the FRP board comprises a lower polyester carrier film (1), a composite layer (32) formed from a polyester resin (3) on the lower polyester carrier film (1) and a glass fiber reinforcement layer (2) contained in the polyester resin (3), and an upper polyester carrier film (12) located on the composite layer (32) of the polyester resin (3) and the glass fiber reinforcement layer (2), and a film stripping cloth (4) is further arranged between the composite layer (32) and the upper polyester carrier film (12). In the present FRP board, the film stripping cloth (4) is additionally arranged between the composite layer and the upper polyester carrier film, and when in use, the upper polyester carrier film (12) and the film stripping cloth (4) are torn off together so that the surface of the composite layer is rough, improving the adhesion of the FRP board to other building materials, and extending the application range of the FRP board.
