A DIC-based study of flexural behaviour of roving/mat/roving pultruded composites

摘要

This paper reports a study of the flexural behaviour and resultant failure modes in E-glass/polyester pultruded composites. The digital image correlation (DIC) method is used to estimate the effect of fibre orientation on failure behaviour in thick beams, taking into account the presence of continuous filament mat layer (CFM) in the stacking sequence. In particular, the tests were carried out for specimens with off-axis angle of 0 degrees, 7.5 degrees, 15 degrees, 30 degrees, 45 degrees and 90 degrees.
