摘要: A binder composition for use in the manufacture of a nonwoven mat including a low-density fiber, and nonwoven mats made with the binder, are disclosed. The low-density fiber is able to reduce the acoustic openness of the nonwoven mats made therefrom while also capable of being delivered with existing binder technology and equipment.

摘要: A high modulus composite part is disclosed comprising a polymer resin; and a plurality of high-performance unidirectional glass fibers. The high-performance unidirectional glass fibers have an elastic modulus of at least 89 GPa and a tensile strength of at least 4,000 MPa, according to ASTM D2343-09. The composite part comprises a fiber weight fraction (FWF) of no more than 88% and an elastic modulus of at least 60 GPa, according to ASTM D7205.
