Roving Combimat Stitched Mat is a composite reinforcement material composed of woven roving and chopped strands or chopped strand mat (CSM), bonded together with polyester stitching thread. This engineered structure is designed to deliver balanced strength and process efficiency, making it ideal for applications such as boat hulls, automotive body panels and doors, cooling systems, and structural profiles.
Key Features:
- Binder-Free Design: Ensures seamless compatibility with polyester, vinylester, and epoxy resins, eliminating chemical interference during resin infusion or lay-up.
- Process Simplification: Integrates multiple reinforcement layers into a single preform, reducing manual layering steps and minimizing labor in composite manufacturing.
- Enhanced Efficiency: Facilitates rapid resin wet-out and uniform consolidation, significantly improving production speed while lowering material waste.
- Structural Versatility: Combines the high tensile strength of woven roving with the surface stability of CSM, providing robust performance in load-bearing and impact-resistant applications.
Typical Applications:
- Marine: Boat hulls, deck structures, and marine equipment
- Automotive: Body panels, door modules, and under-the-hood components
- Industrial: Cooling towers, chemical-resistant apparatuses, and structural beams
This stitch-bonded mat excels in processes requiring both mechanical durability and manufacturing efficiency, such as hand lay-up, vacuum infusion, and automated molding. Its binder-free composition and pre-consolidated layers make it a cost-effective solution for high-volume production across diverse industries.
