ETM450 Unidirectional Glass Fiber Fabric

ETM450 is a stitched unidirectional glass fiber composite reinforcement, constructed with a 230 g/m² 90° roving layer and a 220 g/m² chopped strand layer. The integrated structure combines directional load capacity with excellent conformability for curved surfaces.

It achieves outstanding resin impregnation and is compatible with unsaturated polyester, vinyl ester and epoxy resin systems. Suitable for hand lay-up, vacuum infusion and other composite molding processes.

Commonly used for FRP storage tanks, fiberglass boat hulls and other composite parts that require both directional strength and good drapability over complex curved shapes.

Key Advantages

✅ Combined structure: 230gsm 90° roving layer + 220gsm chopped strand layer ✅ Balanced directional strength and good drapability for curved surfaces ✅ Excellent resin wet-out, easy to work with during lay-up ✅ Compatible with polyester, vinyl ester and epoxy resins ✅ Preferred reinforcement for FRP tanks and fiberglass boat hulls

Application:                                        

● Compatible with reinforced unsaturated polyester resin, vinlyester resin, epoxy resin, phenolic resin and polyurethane resin etc.                                    

● Forming process includes winding, pultrusion, RTM, hand lay-up,vacuum infusion molding and RTM etc.                                                                                                        

● The typical end-use applications are pipe, storage tank, pultruded profile,  FRP boat hull and wind power blade etc.
