Abstract

Conventional wisdom would suggest an expectation that certain material properties of carbon fibre reinforced polymer (CFRP) composites would be negatively impacted by the introduction of perforations; however, initial findings have suggested this not to be the case. The present work will focus on investigating the mechanical properties of laser perforated CFRP composites by means of tensile, flexural, compressive, and short beam shear testing. The test specimens used in this investigation were manufactured from out-of-autoclave carbon fibre prepreg. A direct comparison is made between the perforated and non-perforated specimens in terms of their mechanical performance.
