Investigation of the Impact Properties of Thin-Ply Prepreg at Element Level

Kurzfassung

This paper describes the cooperation between ITCF, JAXA, DLR and Airbus for the research on thin-ply laminates. For the first time the manufacturing and preparation of thin-ply specimen at element level is described. The test campaign is not yet finished, but the first results are quite interesting. In the focus of the test campaign are two kind of specimens. Firstly these are omega-stringer stiffened crippling panels and secondly these are CAI coupons. For both kind of specimen thin and standard ply are compared. The manufacturing, specimen preparation and the first results of the impacting are presented in the following.
