Abstract

The increasing demands in subsea industry such as oil and gas, led to a rapidly growing need f or the use of adv anced, high perf ormance, lightweight materials such as composite materials. E-glass fibre laminated pre-preg, filament wound and braided tubes were tested to destruction under hydrostatic external pressure in order to study their buckling and crushing behaviour. Different fibre architectures and wind angles were tested at a range of wall thicknesses highlighting the advantage that hoop reinforcement of fers. The experimental results were compared with theoretical predictions obtained from classic laminate theory and finite element analysis (ABAQUS) based on the principal that the predominant failure mode was buckling. SEM analysis was further performed to investigate the resulting failure mechanisms, indicating that the failure
mechanisms can be more complex with a variety of observed modes
taking place such as fibre fracture, delamination and fibre-matrix interface
failure.
