Abstract

Classical lamination theory is developed in the following report for the membrane response of filament wound circular cylinders. Experiments are conducted for both internal pressurization and temperature rise. The theory is found to be in reasonable numerical agreement with the average of the experimental axial and circumferential strains for both the mechanical and thermal responses. The largest discrepancy between theory and experiment in the mechanical response occurred for the axial strain where it was concluded that the major contributor to the discrepancy was the manufacturing process of the 0o layers. In the thermal response (for zero pressure) good agreement was obtained in the axial direction and poorer in the circumferential. Several potential sources of discrepancy make these comparisons only approximate. These sources include lack of good material constant data, particularly at high temperature and the strong thermal gradient though the pipe wall (theory was derived for a constant temperature through the pipe wall).
