Abstract

This research aims to study the burst pressure and mechanical behavior of filament wound composite pipes. Also, it was determined the thermal and expansion coefficients for evaluate their effect on the burst pressure of the composite pipes. The filament wound composites were manufactured with different winding angles, from ±35° to ±75°. The mechanical properties was obtained through accurate numerical models based on finite element method (FEM) and the hygrothermal coefficients via analytical approach. The results pointed an increase in the burst pressure up to ±55°, and an abrupt drop after it, for all failure criteria studied. The environmental conditioning reduced the maximum internal pressure strength in 2-3% of the composite pipes.
