Glass Fiber Knitted Felt (Stitched Felt / Glass Fiber Nonwoven Mat)
Glass Fiber Knitted Felt is a nonwoven reinforcement material made by mechanically knitting chopped glass fibers into a soft yet structurally stable fabric using a polyester knitting yarn. Unlike traditional esteras de hebras picadas (CSM), which rely on chemical binders to hold the fibers together, knitted felt is binder-free, offering excellent flexibility, drapability, and enhanced compatibility with various resin systems such as polyester, vinyl ester, epoxy, and phenolic.
Introducción al rendimiento del producto
Knitted felt is composed of short-length E-glass fibers (usually 50 mm or 100 mm) arranged in a random orientation and knitted in a lightweight, open-loop structure, providing uniform fiber distribution, excellent conformability to complex molds, and fast resin wet-out. It is especially favored for hand lay-up, vacuum infusion, RTM, y spray-up applications in marine, automotive, building, and industrial components.
