Chongqing Polycomp International Corp. has developed a family of glass fibers for composites reinforcing with a flat cross section, which the company claims enables higher loading and better mechanical properties.
Benefits include higher impact strength and reduced warpage in thin-wall sections of injection molded thermoplastic composites.
Other benefits include lower shear, which provides better fluidity, reducing friction and viscosity buildup and lowering fiber entanglement and breakage since the flat fibers tend to flow in planar sheets, like mica, rather than rolling and tumbling line conventional round glass filaments, the company claims.
Polycomp comes in filament widths of 28 microns, and filament thickness of 7 microns. They get turned into chopped strands.
The company is based in Dadukou, China and is a subsidiary of YTH Group. A global conglomerate of glass-fibers, mineral composites, textiles, financing and trading companies.
The U.S. operation is in Amsterdam, N.Y.
