The pultruded profile is a composite material formed by glass fiber as the reinforcing skeleton material and thermosetting resin as the matrix bonding material. The continuous roving of glass fiber makes the product have extremely high longitudinal strength. Etc.) The product has good lateral strength; the thermosetting resin matrix is usually unsaturated polyester resin, vinyl resin, epoxy resin and phenolic resin can also be used, the resin matrix makes the product have good corrosion resistance, different resins make The product can be applied to various harsh corrosive environments. Adding anti-ultraviolet absorber and flame retardant can make the product have excellent anti-aging properties and different levels of flame retardant properties. Adding polyester fiber surface felt on the surface of the product can obtain corrosion resistance and aging resistance. Generally, the glass fiber content of the pultruded profile is 45% -75% (weight ratio), and the rest are resin and additives. Unsaturated polyester resin and vinyl resin are the most commonly used resin matrix.
