<p>A new and further improved multi-ply fabric, and process for the manufacture of such fabric, particularly useful in boat building wherein the fabric must fit or assume the shape of compound-curved surfaces to suitably serve as a base or support for resin or liquefied plastics added thereon and cured or hardened as an initial step in the formation of, e g., a fiberglass reinforced plastic boat hull. The fabric is characterized generally as of a two-ply construction embodying an upper and lower ply between which is "sandwiched" and secured a series of parallel aligned, spaced apart, springy elements of specific character between which can be placed yarns or rovings to impart tensile strength. The plies of the fabric consist of parallel aligned, continuous, pliable filaments bonded to said springy, plastic elements, each filament being laterally aligned with respect to said springy elements, the filaments being sufficiently pliable or flexible to permit some lateral or tansverse movement, and also longitudinal movement, of the springy elements so that the fabric construction can assume compound-curved shapes.</p> |
