The invention discloses a fiber-reinforced composite material pultrusion forming device and a pultrusion forming process thereof, belonging to the field of composite material processing. It includes a closed glue injection box on the side where the yarn guide plate moves along the reinforcement material, a glue injection system that is airtightly connected to the glue injection box, a mold that is arranged on the side where the glue injection box moves along the reinforcement material, And a lubricant injection system that is airtightly connected to the mould. The present invention injects lubricant into a lubricating groove by adding a lubricating groove to the solidification area after the gel point of the resin on the pultrusion metal mold, and uses the lubricant to reduce the frictional resistance between the product and the inner wall of the mold when the product moves in the mold, thereby significantly reducing the pultrusion traction force. The invention solves the problem that the amount of the release agent added to the release agent has limitations in reducing the resistance, and is especially suitable for the processing of special-shaped materials with complex structures that require relatively large traction force.
Description
technical field [0001] The invention belongs to the field of composite material processing, in particular to a fiber-reinforced composite material pultrusion forming device and a pultrusion forming process thereof. Background technique [0002] The pultrusion molding process is to continuously produce glass fiber reinforced plastic profiles of unlimited length through extrusion die molding and curing of continuous glass fiber bundles, tapes or cloth and other reinforcing materials impregnated with resin glue under the action of traction. This process is most suitable for the production of FRP profiles of various cross-sectional shapes, such as rods, tubes, solid profiles (I-shaped, trough, square profiles) and hollow profiles (door and window profiles, blades), etc. The matrix resins used in pultrusion mainly include thermosetting resins such as unsaturated resins, vinyl resins, phenolic resins, epoxy resins, and polyurethanes. [0003] The typical process of pultrusion is:...
