Evaluation of damage accumulation of glass fibre reinforced chemically bonded ceramics (CBC) using the resonalyser technique

This paper gives a summary of tests performed on laminates consisting of an inorganic phosphate cement (called IPC), developed at VUB, and unidirectional continuous glass fibres. Tests with limited loading/unloading cycles at different stress levels are performed. During the tests, Young’s modulus and residual strain can be measured. The goal of the research is to find a non-destructive ‘tool’ to describe the ‘state’ of the examined composites. For this purpose the specimens were examined using a non-destructive mixed numerical/experimental technique developed at the department of Structural Analysis of the VUB, the so called ‘Resonalyser’ technique.
