Abstract

Unidirectional hybrid composites were fabricated by sandwiching single plies of two different types of thin, dry spread tow carbon fibre tapes between double plies of a conventional glass fibre-epoxy prepreg system. Tensile tests were carried out under optical video monitoring for later damage analysis. In the case of the specimens reinforced with a single layer of the thicker carbon fibre tape (68 g/m2), the failure type of the carbon layer was sudden and catastrophic. In the case of the thinner carbon fibre tape reinforcement (40 g/m2) a stable, pseudo-ductile damage process was observed, which was well pronounced on the stress-strain curves. Observed damage characteristics agreed well with the performed simple fracture mechanics analysis.
