FRP Pultrusion Matrix solidification

(1) Hand laying method (HLU): It is formed by immersing the artificial substrate on the reinforcing material and stretching it on the mold to the desired thickness to cure the substrate at room temperature and pressure.

(2) Spray forming method (SU can SPU): the roving side of the continuous cut off together with the matrix with the spray on the mold, straight to the desired thickness of the pressure to his plastic, under normal pressure at room temperature.

(3) Resin Transfer Molding (TRM): After the reinforcing material is placed in the mold, it is clamped and clamped, pressed into the substrate from the specified position, and cured.

(4) cold forming (CP): mainly preformed reinforced material (called preform: PF or PM) placed in the mold, and then add the curing agent, filler. Coloring agent and the like are mixed into the base resin after being mixed and pressed, and pressed at a relatively low pressure on the male mold with a press, and cured at a temperature close to room temperature.

(5) metal mold molding method (MMD): with a pair of yin and yang metal mold, plus high pressure at the same time heating, to fast curing molding. The method of preforming is called preform method. The method of using SMC is called SMC method, and the method of BMC is called BMC method.

(6) Fiberglass forming (FW): A method of forming a substrate with a roving or a long fiber while being impregnated with a substrate and wrapped around a swivel-shaped mold.

(7) Pultrusion method (PULT): the impregnation of the matrix of the reinforcement material into and through a certain section of the mold has been heated to make it quickly and continuously lap molding.

(8) Vacuum bag method (VB): The impregnated matrix of the reinforcing material, stacked on the mold and sealed with a plastic film, with a vacuum inside the reinforced material and the surrounding air and the remaining matrix at the same time out and solidified forming.

(9) Hot pressing (AC)

Is a technology for the production of glass fiber reinforced plastic profiles, which produces high-performance space-time composite materials suitable for the use of doors and windows manufacturing.

The continuous glass fiber reinforced material is passed through a resin impregnation station in the form of roving and mats so as to coat the outside of the glass fibers with a specially formulated thermosetting resin mixture. The resin-coated fiberglass material is combined through a forming guide and is pulled out through a mold, subjected to pressure and heat in the mold, and the resin is cured to obtain a high-strength profile. After leaving the extruder, Profiles can be used immediately. The process is irreversible and it can not be melted or re-shaped again. This is different from PVC (polyvinyl chloride). PVC will be deformed under heat.
