 Overview : 

FRP square tube is a composite material formed by glass fiber as reinforcing matrix material and thermosetting resin as matrix bonding material. Glass fiber continuous roving makes the product have high longitudinal strength, glass fiber felt (Continuous felt, knitted felt, etc.) to give the product a good transverse strength; the thermosetting resin matrix is usually an unsaturated polyester resin, a vinyl resin, an epoxy resin and a phenolic resin, and the resin matrix gives the product good corrosion resistance. Performance, different resins make the product suitable for a variety of harsh corrosive environments, the addition of anti-UV absorbers and flame retardants can make the product have excellent anti-aging properties and different levels of flame retardant properties.

 Production Process : 

The roving and the woven frame are made of glass fiber continuous roving, glass fiber felt and other reinforcing materials under the traction of the pultrusion machine, impregnated with the resin through the resin bath, and then formed by a preforming mold which maintains a certain cross-sectional shape and is heated by the metal mold. A process for curing, finally cooling and automatically cutting, continuously producing an equal-section FRP profile. The pultrusion process is an advanced mechanized composite material forming process. The process has small environmental pollution, high production efficiency, low cutting loss, no waste scraps, and can produce FRP profiles of any length and other sections.lj-11
