Structural filler material for resins.
 |
The most common filler material is matting and roving. It comes in many different sizes and weights. These materials are available in many variations, like E-glass, carbon fiber, Kevlar and more. Matt adds stiffness to the product, used as a bonding material between layers of roving. The strength comes from the roving. The difficulty with roving is working the material into complex shapes. In high-performance applications, the rule of thumb is keeping resin content and matting as low as possible! |  |
