ABSTRACT:
A continuous composite structure manufacturing apparatus which comprises a conveyor or conveyors for conveying one or more fabric webs along a conveying path. Each of the webs is comprised of a reinforcing fabric, a non-woven fabric, or a layered fabric. The fabric web is passed through the conveyor so that it defines an enclosed foam injection zone. A foam injection system is provided for injecting foam into the foam injection zone to form a foam core preform (or a plurality of same). One or more dies are positioned along the conveying path, to shape each of the foam core preform(s) to a desired cross-sectional profile. The individual stringers or multiple, spaced apart, stringers are produced concurrently in a continuous production process.
