FIBER COMPOSITE WITH REDUCED SURFACE ROUGHNESS AND METHOD FOR ITS MANUFACTURE

Fiber reinforced composites are made by infusing a mass of reinforcing fibers with a resin composition (11). A thin sheet (6) of nano-sized monofilaments (7) is applied on at least one major surface of a fiber mass. The resin composition (11) is subsequently hardened to form the composite. This meth...

More Information
Summary:Fiber reinforced composites are made by infusing a mass of reinforcing fibers with a resin composition (11). A thin sheet (6) of nano-sized monofilaments (7) is applied on at least one major surface of a fiber mass. The resin composition (11) is subsequently hardened to form the composite. This method produces a composite having a very smooth surface. Printout of the reinforcing fiber is greatly reduced without the need to mask it through the application of thick coatings or additional layers of material.
