aerospace laminate M21/T800S (autoclaved and hot pressed) and the woven fabric ECG Carbon 12k
with respect to the ASTM Standard D5582. Simultaneously the materials were monitored by acoustic emission to
evaluate the results via burst analysis. CFRP-specimens were mounted in a CNC-machining center by a chopper
wire. The lower wire was fixed at a load cell (KISTLER 9257 B) to measure the force development. Standard
specification the movement speed in z-direction was set to 5 mm/min. The acoustic emission sensor iMPact XS
with accuracy is±5% with a reference sensitivity of>1200 pC/N was fixed on the DCB-specimens with a twosided
adhesive tape with thickness of 0,5 mm. The sensor iMPact XS has a frequency range from 1 mHz up to
1 MHz limited to a maximum of 500 kHz. It has been found that the material properties correlate well with the
results of the acoustic emission analysis. The burst rate reflects the manufacturing processes as it is influenced
directly by the fibre bridging which occurs particularly for autoclaved composites. In contrast, the burst energy
is not affected by the manufacturing process. It is only depending from the matrix properties.Pracoviště Ústav geoniky Kontakt Lucie Gurková, lucie.gurkova@ugn.cas.cz, Tel.: 596 979 354 Rok sběru 2019 Elektronická adresa http://www.sciencedirect.com/science/article/pii/S1359836817313720
