Abstract
This disclosure includes fiber-reinforced composites including and/or formed in part from fibrous non-woven layers, stacks of layers that can be consolidated to form such composites, articles, such as portable electronic device housing panels, including such composites, and methods for making such composites and articles. In some composites, at least one of the non-woven layer(s) includes: (1) a first thermoplastic material that may be present as a first set of resin fibers; (2) a second thermoplastic material that may be present as a second set of resin fibers, the second thermoplastic material having a transition temperature and/or a low-shear viscosity that is higher than that of the first thermoplastic material; (3) a first set of reinforcing fibers; and/or (4) a second set of reinforcing fibers of a type distinct from that of the first set of reinforcing fibers.
