A curve shaping apparatus includes: a heating device provided in a path and heats a reinforcing fiber material; a clamping mechanism switches between a clamping state and a non-clamping state; a swing mechanism including a gripping unit that switches between a gripping state and a non-gripping state, the swing mechanism rotationally drives the gripping unit between an initial position and a rotation position; a shaping mechanism including a shaping mold unit that includes an upper mold, a lower mold, and a pair of side molds for shaping the reinforcing fiber material; a pulling-out mechanism performs a pulling-out operation; and a drive control device configured to control drive of each mechanism so that each process of a rotation process, a pulling-out process, and a shaping process is performed.

A pultrusion system for preparing a fiber reinforced polymer composite includes three movable sleds positioned adjacent one another and longitudinally aligned with one another to feed a composite material through a system. Each of the sleds has an open position and a closed position, with the closed position being utilized to clamp down upon and pull a composite material through the pultrusion system. The system provides for two of the three sleds to be in contact with the composite material to move the composite material through the system at any one time.

A pultrusion molding apparatus for manufacturing a vehicle member. The interior of the vehicle member is divided into a plurality of regions by at least one rib and the vehicle member is formed from a composite material to have a constant thickness. The pultrusion molding apparatus includes a molding unit configured to mold the vehicle member by applying a fiber and a non-woven fabric while impregnating the fiber with a resin. The molding unit includes: an upper mold in which a space is formed; a lower mold disposed below the upper mold and coupled to the upper mold; and a mandrel configured to be inserted into a gap formed between the upper mold and the lower mold and having one end fastened to the upper mold.

A method and an equipment for preparing a pultruded polyurethane composite by a polyurethane pultrusion process, and the pultruded polyurethane composite obtained by the method and use thereof are provided.

A method and an extrusion or pultrusion device for forming a profile product made from a material in a production direction, said device comprising a rotating die, extending in a radial direction and a width direction, having two opposite first and second side walls and an outer circumferential surface extending in the width direction therebetween, wherein the rotating die comprises a first side portion in connection to the first side wall and a second side portion in connection to the second side wall and a mid-portion extending between the first and second side portions, and a profile definition zone having a longitudinal direction coinciding with the production direction, a height direction and a width direction being perpendicular to the height direction, comprising a through channel comprising a first channel section followed by a second channel section downstream the first channel section with reference to the production direction, wherein the rotating die is rotatable about an axis extending across the production direction and arranged to allow the outer circumferential surface to, while the rotating die rotates, exert a pressure onto a surface of the material when fed through the profile definition zone.
