Strain Concentration and Fracture at the Impact Site during the Compression of a Carbon/Epoxy Composite
Original language description
Polymer composite panels are widely used in aeronautic and aerospace structures due to the high strength-to-weight ratios of these structures. A series of compression-after-impact (CAI) tests was performed on a composite made of a carbon-fibre-reinforcedepoxy resin matrix. The objective of this study is to determine the strain fields and failure mechanisms during the failure of the impacted composite laminates when subjected to compression. A digital image correlation and fractographic analysis by means of optical and electron microscopy are used for this purpose. The full-field strain measurements indicate a concentrated band of compressive strain near the impact, where buckling occurs. The results indicate that the strain concentration factor can beconsidered to be a failure criterion. The shear strain visualisation around the impact reveals an area of heterogeneous deformation that is comparable to the detected delamination area acquired by an ultrasonic technique. Fibre and inter
