CRTM™ Composite Sandwich Panels
Strong, Lightweight, Structural
CRTM™ (continuous resin transfer molding) panels are thermoset composite sandwich panels with tailored, multi-axial fiber reinforcements, high-fiber volume and very low void content. These custom-engineered products are available with a wide variety of core materials, including end-grain balsa, foam or engineered woods and laminate face-sheets with continuous fiberglass and/or carbon fiber reinforced polyester, vinyl ester and epoxy or custom resins.
Panels are custom engineered to meet customer needs by varying core thicknesses to affect stiffness, core materials to affect weight, fiber to modify the stiffness-weight ratio, and resin material to affect strength.
Impact
- Improved thermal insulation
- Reduced component complexity compared to metal
- Unlimited continuous lengths with widths of up to 108 inches
- Vibration damping and acoustic insulation
- Designed for applications needing a high stiffness-to-weight ratio
- More consistent quality throughout the panel than pultrusion
- Better control of fiber alignment and resin kinetics
