Title: (EN) METHOD AND APPARATUS FOR STRUCTURAL ATTACHMENT OF POLYCARBONATE PLASTIC SHEET TO SUPPORTING STRENGTH MEMBERS AND AIR CARGO CONTAINER UTILIZING SAME
(FR) DISPOSITIF D'ASSEMBLAGE DE FEUILLES DE PLASTIQUE POLYCARBONATE SUR DES ELEMENTS D'OSSATURE ET CONTENEUR DE FRET AERIEN FABRIQUE SELON CE PROCEDE
Abstract: front page image
(EN) In order to be able to utilize polycarbonate sheet material (12) as a structural (i.e. stress-bearing) component in an assembly comprising polycarbonate (12) and metal (10) components, as, for example, in a monocoque air cargo container wherein the polycarbonate sheet material (12) is used as the "skin" of the structure, an attachment assembly is utilized to provide a rigid, stress-bearing joint without inducing crack-inducing high levels of localized stress on the polycarbonate sheet (12). The attachment assembly (14) comprises a significant area of overlap between the polycarbonate (12) and metal (10) components, and an attachment strip (14) which substantially covers the attachment area, Rivets or bolts (16) are inserted through oversized holes in the metal (10), polycarbonate (12), attachment strip assembly (14) and then torqued. The compressive forces exerted thereby create the rigid joint (even in an environment where the joint is subject to 180 °F~ temperature cycling such that the different coefficients for thermal expansion for the polycarbonate vs. the metal become significant) but are spread over a sufficiently large area so as to avoid high, localized stress levels which would induce the polycarbonate to crack.
