Phenolic Molded FRP Grille Has New Method

A phenolic-molded FRP grating method, which was announced a few days ago, consists of a grille body and a stressed rib on a grid joint. According to experts, the feature is that the force ribs are at least one stepped up and down contraction. The utility model changes the structure of the molding grille, that is, the force-receiving ribs of the grille are at least one stepped up and down contraction, so that the effective load-bearing area of ​​the top surface of the grille is increased, and the strength in the force direction is increased. Improve the ablation resistance and greatly increase the residual strength of the grid after ablation, so as to meet the inspection standards. In addition, the utility model does not increase the self weight of the grid, and the cost of the utility model is greatly reduced compared with similar products, and is a competitive product.
