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.
Contact Lattice Composites to learn more about acquiring a winding resin that is custom formulated to fit your process or need.
| Advantages | |
|---|---|
| Feature | Benefit |
| No mixing (single components) | Faster throughput, easier process |
| Can be re-used (single components) | Less waste |
| Not a VOC (Volatile Organic Compound) | Less PPE |
| Stable at winding temperatures for 8+ hours | No time limit on winding |
| Customized strength, stiffness, mechanical properties | Focused towards specific applications |
| Mild cure | Creates crack free parts |
| High glass transition temperature | Keep strength in hot environments |
| Superior mechanical properties | Allows for smaller usage, lighter parts |
| Toughened | Impact resistant |
