Fabrication of Uniaxial Filament-Reinforced Epoxy Tubes from Structural Applications,

Abstract

A process has been developed for fabricating uniaxial filament-reinforced epoxy tubes. The process utilizes hand layup techniques, a Teflon mandrel, and a heat-shrinkable Teflon sleeve. At the present, over 40 tubes of boron-epoxy and S-glass-epoxy have been fabricated using the process reported herein. The tubes are essentially void free, exhibit less dimensional variation than the tolerances set for commercially available extruded aluminum tubing, and display a smooth surface finish. Short sections of both types of tubing have been subjected to axial compression tests. The boron-epoxy and S-glass-epoxy tubes exhibited average strengths of 309 ksi (2.13 GN/sq m) and 207 ksi (1.43 GN/sq m), respectively.
