摘要
In general, coated fibers, methods of bonding a coating to fibers, and composite materials prepared from coated fibers are provided. The coated fiber is created with a surface that is compatible with and bonds to the polymer resin used in composite materials. In another aspect, the coating may exhibit additional functionality, such as water repellency, fire resistance, or odor control. More specifically an atmospheric pressure plasma process is applied to the fibers to bond coating materials to the fiber surface and to cure the coating surrounding the fiber surface. Optionally, radiation is used in the process to cure the coating. Finally, composite materials and parts may be made from the coated fibers that exhibit high strength and improved mechanical properties over composites made with uncoated fibers. Alternatively, a natural fiber reinforced composite material is made from coated natural fibers that has improved mechanical properties and decreased water absorption.
