1. A method of forming a thermal and acoustic composite material comprising the steps of:

  • at least partially opening a bundle of wet reinforcement fibers;

    removing at least a portion of water present in said wet reinforcement fibers to form dehydrated reinforcement fibers;

    blending first thermoplastic polymeric fibers with said dehydrated reinforcement fibers to form an acoustical composite layer; and

    affixing a first thermal layer of second thermoplastic polymeric fibers to a first major surface of said acoustical composite layer, said second thermoplastic polymeric fibers being the same as or different than said first thermoplastic polymeric fibers.
