Acoustic emission for interlaminar toughness testing of CFRP: Evaluation of the crack growth due to burst analysis
Original language description
The paper deals with interlaminar fracture toughness testing of three different types of specimens from unidirectionalnaerospace laminate M21/T800S (autoclaved and hot pressed) and the woven fabric ECG Carbon 12knwith respect to the ASTM Standard D5582. Simultaneously the materials were monitored by acoustic emission tonevaluate the results via burst analysis. CFRP-specimens were mounted in a CNC-machining center by a choppernwire. The lower wire was fixed at a load cell (KISTLER 9257 B) to measure the force development. Standardnspecification the movement speed in z-direction was set to 5 mm/min. The acoustic emission sensor iMPact XSnwith accuracy is±5% with a reference sensitivity of>1200 pC/N was fixed on the DCB-specimens with a twosidednadhesive tape with thickness of 0,5 mm. The sensor iMPact XS has a frequency range from 1 mHz up ton1 MHz limited to a maximum of 500 kHz. It has been found that the material properties correlate well with thenresults of the acoustic emission analysis. The burst rate reflects the manufacturing processes as it is influencedndirectly by the fibre bridging which occurs particularly for autoclaved composites. In contrast, the burst energynis not affected by the manufacturing process. It is only depending from the matrix properties.
