SIZING COMPOSITION FOR GLASS FIBERS USED TO REINFORCE THERMOPLASTIC OR THERMOSETTING MATRIX POLYMERS

摘要

The present invention relates to a sizing composition for glass fibers used to reinforce thermoplastic resins, such as polyolefins, and particularly, polypropylene. The composites produced with the fiber strands coated with such sizing compositions have improved fiber adhesion and retention of fiber length. In addition, a method for improving tensile creep and tensile fatigue in polypropylene composites reinforced with glass fibers is provided.
