FRP Rebar Making Machine 4-36mm with High Efficiency High Output

Glass fiber has the advantages of high tensile strength, low elongation, good corrosion resistance, etc. Compared with carbon fiber and basalt fiber, this kind of raw material is easier to obtain, and the price is relatively simple, and the production process is relatively simple and mature, which is convenient for industrial promotion and application.

Epoxy vinyl resin contains less ester bonds, which improves its alkali resistance. The main chain contains more secondary hydroxyl groups, which improves the resin’s wettability and adhesion to glass fibers, and helps to improve the product’s performance. Mechanical strength.

The pultrusion process is mainly to pass reinforcing materials such as felt, belt, and continuous untwisted yarn through the infiltrating resin, then pass through the garbage mold, and then draw by the tractor, so as to continuously produce products such as glass fiber ribs with unlimited length.

The winding process is a process in which the reinforced materials (continuous fiber bundles, fiber cloth, etc.) fully dipped in glue are wound on the core mold according to a certain rule, and then cured and demolded to make glass fiber reinforced products.

The mechanical strength of the glass fiber tendons is mainly determined by the fibers, and the main function of the matrix resin is to bond the bundles of fibers together for the transfer of stress and strain.

If the bond between the resin and the fiber is not good, the stress will not be effectively transmitted between the fibers, and it will be difficult for the fiber to bear the main load.
