FRP sculpture wood model
Wood formwork is mainly used for large products with straight line. The wood mold can be directly used as the forming mold of FRP products, and can also be used as the transition mother mold for turning FRP molds. The wood used for making molds includes Korean pine, gingko, Chinese fir, etc. the water content is required to be up to 15%, and it is not easy to shrink and deform without knots. After the wood mold is made, it can be coated with resin (surface putty) with a thickness of 0.2 ~ 0.3 garbage, polished four times from coarse to fine with sandpaper, polished with 800# or 1000# sandpaper for the last time, coated with polishing paste, polished with a polisher, and then marked with paraffin. The wood mold can also be directly painted and polished to make the wood mold.
Light weight and high strength
The relative density is between 1.5 ~ 2.0, which is only 1 / 4 ~ 1 / 5 of that of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength can be compared with that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels and other products that need to reduce self weight. The tensile, flexural and compressive strength of some epoxy FRP can reach more than 400MPa.
Good corrosion resistance
FRP is a good corrosion-resistant material. It has good resistance to atmosphere, water, acid, alkali, salt of general concentration, as well as a variety of oils and solvents. It has been applied to all aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
