摘要： Described herein are reinforced thermoplastic polymer compositions including a flat, low-dielectric glass (“D-glass”) fiber. D-glass fiber compositions with a flat morphology provide for polymer compositions having significantly reduced shrinkage and excellent mechanical and dielectric performance. While the flat D-glass fibers can be desirably incorporated into polyester polymers, poly(aryl ether sulfone) polymers, poly(aryl ether ketone) polymers and a polyphenylene sulfide polymers.
