Abstract: A nonwoven fabric useful for forming composite panels includes specific amounts of reinforcing fibers, a polyimide, and a block polyestercarbonate-polysiloxane. The nonwoven fabric has a density of 0.03 to 0.2 gram/centimeter3, an areal density of 100 to 400 gram/meter2, and a tensile modulus of 50 to 1000 megapascals. Also described are a method of forming the nonwoven fabric, a composite formed from the nonwoven fabric, and a method of forming the composite.

Abstract: A polymer laminate and a method for manufacturing a polymer laminate are disclosed. The polymer laminate includes a first layer having a first surface and a second surface. The first layer includes a first non-porous polymer material. The polymer laminate also includes a second layer on the first surface of the first layer. The second layer includes a first porous polymer material defining a first plurality of pores, and the first non-porous polymer material located within the first plurality of pores.
