Abstract: Through the static load test of acoustic emission in the glass fiber composite sample, the authors studied the damaging process of the acoustic emission characteristics for this kind of materials under static test conditions. They analyzed the material damage at all stages of the acoustic emission characteristics and the corresponding load ratio, and achieved the type of the material characteristics and sound propagation characteristics systematically and integrality. Test results proved that under static load conditions, the acoustic emission test can effectively and clearly uncover the material static test conditions in damage process of acoustic emission characteristics and the material damage type characteristic, which provided the evaluation basis for the material life health monitoring and defect judgment.
