The relationship between FRP pultruded profile and FRP guardrail
FRP pultruded profiles are generally made of polyester resin, surface mat, continuous mat and glass fiber, etc., which are cured at high temperature through a pultrusion process with constant cross-section structural profiles. There are many types of FRP pultruded profiles , such as FRP pultruded round tubes, FRP pultruded square tubes, FRP pultruded rectangular tubes, FRP pultruded round bars, FRP pultruded I-beams. The pultrusion process is a special process in the FRP forming process. It is suitable for the production of FRP pultruded profiles with various cross-sectional shapes. It is to impregnate untwisted glass fiber roving and other continuous reinforcement materials with resin, and then maintain a certain It is a composite material production process of forming a pultrusion product by forming a molding die with a cross-sectional shape and making it solidify in the die and then continuously exit the die The glass fiber reinforced plastic square tube or round tube ...
