Evaluation of C/PPS Composite Fatique Behaviour Using Acoustic Analysis
Original language description
Abstract: This paper deals with investigation of acoustic material degradation indicator (natural frequency) of carbon fibre C/PPS composite obtained by a custom-built experimental device. The specimen's sound was emitted during the impact of steel pellet in acoustic measurement experimental device. Acoustic signals were recorded and analyzed using spectral and regression analysis. Specimens were repetitively measured after designated number of loading cycles. The decreases of natural frequencies were determined for given number of natural modes. Relations between natural frequency values and their decreases were investigated. To conclude, the data assessed using acoustic measurements are suitable for evaluation of material degradation.
