Empowering Precision, Defining Efficiency.
Carbon Fiber RTM Core Mat (Closed Mold Mat CF) is a high-performance reinforcement material made of a synthetic non-woven core, laminated with chopped glass fibers or a mix of chopped glass and multiaxial/woven fabrics. It ensures good resin flow, uniform thickness, and enhanced mechanical strength.
Designed for RTM, vacuum forming, injection molding, and SRIM processes, it is widely used in FRP parts for boats, vehicles, aircraft, and panels, offering strength and weight reduction in one solution.

Carbon Fiber RTM Core Mat (also known as Closed Mold Mat CF) is a multilayer reinforcement material composed of a synthetic non-woven core laminated with chopped fiberglass or a hybrid of chopped glass and multiaxial/woven fabrics.
It ensures fast resin wet-out, consistent laminate thickness, and high mechanical performance in structural composite parts.
1. Excellent Resin Flowability – Ensures efficient infusion and air release during RTM or vacuum molding
2. Lightweight Core – Reduces overall part weight without compromising strength
3. Stable Thickness Control – Delivers uniform thickness throughout the molded part
4. Versatile Fabric Combinations – Available with chopped glass, multiaxial or woven fabric reinforcements
5. Dimensional Stability – Maintains shape and structure under pressure and heat
One roll is wrapped in plastic film and then placed into a carton or a large carton.
Normally, P4 (4 big rolls) or P7 (4 big rolls + 3 small rolls) or 6, 9, or 12 small rolls are packed per pallet horizontally/vertically. It can be customized based on the loading method.
Fiberglass products should be stocked in a dry, cool, and waterproof place. The best condition is with a temperature between 15-35℃, with a relative humidity between 30%-65%. Please keep the product in its original packaging before use, avoiding moisture.
