dc.description.abstractThis paper is part of a series of fractographic studies on fiber-reinforced polymer composites submitted to compression, which attempts to fill the gap in the composite failure analysis. Here, the effect of the hygrothermal conditioning is assessed for composite laminates manufactured from a carbon fiber/epoxy resin prepregs, which used plain weave fiber arrangement. The laminate was trimmed into compression test specimens, according to the ASTM D3410 standard. After the test, the aspects of the failure were investigated using a scanning electron microscope, so the compression failure modes could be identified. The fractographic analysis indicates that the lower compressive strength of the conditioned specimens was caused by a decrease in the stiffness of the polymer matrix, due to the plasticizing effect of the moisture exposure.en
