Lattice Composites Winding Resins (LCWR) is a group of resin systems designed to be used in filament winding processes. All LCWRs are compatible with epoxy sized E-glass and various carbon fibers. Lattice has developed single and two component winding resin systems, both of which provide composite parts with excellent mechanical properties. Each of the winding resin systems is highly customizable.
