Compressive Properties and Column Efficiency of Metals Reinforced on the Surface with Bonded Filaments.
Abstract
A design concept which could be utilized during the development period of the all composite structure is that of enhancing conventionally designed metallic structures with resin bonded filaments. This concept has considerable practical merit, since it retains the large background of technology developed for metal aircraft. For example, considerable weight saving is indicated if the longitudinal elements of monocoque structures are surface reinforced with axially alined filaments. The axially loaded filaments are utilized efficiently and minimum amounts of the filamentary material are required. Shear stresses and inplane direct stresses are supported by the metal structure. The purpose of this paper is to report the results of an exploratory research program conducted to determine the potential for weight saving offered by conventional metals reinforced on the surface with resin bonded filaments. The program involved a series of filament reinforced tubular compression specimens designed to indicate feasibility and to provide the strength and stiffness values necessary to demonstrate the weight saving potential of filament reinforced metals. The compressively loaded tube was selected for study because it lends itself conveniently to filamentary reinforcement and laboratory testing. In addition, tube columns are attractive because of the relatively simple and well developed analytical expressions for load carrying capacity and structural efficiency.
