Abstract

A hinged component fabrication method in which, in a layup stage of fabrication, the component includes a live hinge joining uncured material portions together at a hinge region and comprising a layer of tensile fabric at least partially infiltrated by an uncured elastomer layer at least partially interposed between the tensile fabric and the uncured material portions such that the uncured elastomer blocks the uncured material portions from infiltrating the hinge region. The method may include locating overlapped tensile fabric and elastomer layers in a tool and introducing polymer-based material into the tool such that polymer-based material portions overlap respective opposite ends of the fabric and elastomer layers. The polymer-based material portions are formed to a desired shape using the forming tool so that the fabric and elastomer layers form a live hinge between the polymer-based material portions.
