Abstract
Abstract As it had been observed that pressure loads encountered on such large acrylic parts as canopies, astrodomes, blisters, noses, windshields, and the like, caused frequent replacements, particularly at attachment points, it was determined that an improved method of attachment must be developed. In this paper is described an improved method of edge attachment for the canopy of the P-80 airplane in which aerodynamic and cockpit pressure loads have imposed higher loads than usual in the acrylic canopy material. In tests, laminated edging integrally attached to acrylic sheeting consistently approached and in certain cases developed the full strength of the cast acrylic sheeting.
