The Mode I and Mode II fracture behaviour of three carbon-epoxy composite laminates with different fabric reinforcement and different matrices was investigated. Standard Double Cantilever Beam (DCB) and End Notched Flexure (ENF) delamination tests were performed to determine initiation toughness and to asses the subsequent crack propagation behaviour. Various toughening mechanism, acting at the microscopic level and responsible for the stick-slip propagation behaviour observed, have been identified. The effect of temperature in a range from -60° to 165 °C was investigated.

Abstract
The Mode I and Mode II fracture behaviour of three carbon-epoxy composite laminates with different fabric reinforcement and different matrices was investigated. Standard Double Cantilever Beam (DCB) and End Notched Flexure (ENF) delamination tests were performed to determine initiation toughness and to asses the subsequent crack propagation behaviour. Various toughening mechanism, acting at the microscopic level and responsible for the stick-slip propagation behaviour observed, have been identified. The effect of temperature in a range from -60° to 165 °C was investigated.File in questo prodotto:
