Industry News: The production methods of FRP are roughly divided into two categories: wet contact type and dry pressure forming. At present, more than 90% of FRP products in our country are still produced by hand lay-up method. Others include moulding method, winding method and lamination method. From the perspective of all countries in the world, hand lay-up still accounts for a considerable proportion, indicating that it still has vitality. The characteristic of the hand lay-up method is that it is molded with wet resin, the equipment is simple, the cost is low, and the overall product can be pasted more than 10m at a time. Disadvantages are low degree of mechanization, long production cycle and unstable quality. Therefore, domestic hand layup workers are still widely welcomed, and mastering certain hand layup techniques is still a good stepping stone for those who have just entered this field.
The application of glass fiber reinforced plastics: glass fiber reinforced plastics are widely used in various fields of industrial life today. It can be said that glass fiber reinforced plastics is an all-rounder. Like using it as a fuel tank and pipeline on a jet aircraft, it can reduce the weight of the aircraft. Astronauts on the moon, the tiny oxygen cylinders on their backs are also made of fiberglass. In addition, the glass fiber reinforced plastics processing is relatively easy, stainless and not rotten, no paint. my country has widely used glass fiber reinforced plastics to manufacture various small motor boats, lifeboats, yachts, and automobile manufacturing, saving a lot of steel. The film industry is used to make props, which is convenient and fast, and saves costs. Can imitate many kinds of material effects. Welcomed by people. The chemical plant also uses phenolic resin glass fiber reinforced plastic instead of stainless steel to make various corrosion-resistant equipment, which greatly extends the life of the equipment. FRP is non-magnetic and does not block the passage of electromagnetic waves. Using it as a radome for a missile is like putting on a pair of protective glasses for the missile, which not only blocks the radar's "line of sight" but also plays a protective role. Now, the radomes of many missiles and ground radar stations are made of fiberglass. In the 21st century, the good wave permeability of FRP is also widely popular with mobile phone communications. FRP is widely used in the manufacture of 2G and 3G antenna covers. In terms of municipal administration, FRP has played a good role in community beautification due to its good formability and appearance beautification. Products in this area include square column wire cover, artificial stone, and beautification tree for field application.
