Experiments to Determine Elastic Moduli for Filament-Wound Cylinders.
Abstract
Elastic moduli for filament wound cylinders having a wall configuration composed of several alternating helically and circumferentially wrapped layers are determined experimentally. The moduli were determined from measurements made on several glass epoxy cylinders and tubes loaded in pressure, torsion, or compression. Computations of elastic constants were made for the test specimens as well as for hypothethical boron epoxy cylinders to demonstrate the importance of the matrix in determining extensional stiffness. A comparison of calculations and experiment indicates that moduli measured in regions where the cylinder matrix behaves linearly are in reasonable agreement with computed values.
