Experiments and Analyses for Determining Fibre/Matrix Interface Parameters – Understanding Debonding Problems
Abstract
A new experimental technique is developed to monitor the initiation and propagation of adebond crack during a fibre pull-out experiment. The advanced experimental setup consists of a high resolution video camera and a laser extensometer mounted at a tensile test machine. The test setup enables the measurement of the fibre/matrix displacement and debond length. A micromechanical model is used for analysing the experimental data. It allows the evaluation of the following parameters: the interface debond energy GIIc and the frictional sliding shear stress τs at the fibre/matrix interface, and the misfit strain ΔεT, accounting for initial residual stresses. Specimens of a single steel fibre embedded centrally in a polyester matrix are tested using the experimental setup and the model. A practical experimental procedure for establishing the interface parameters is suggested, and an example demonstrates the procedure and yields a set of interface parameters.
