| Abstract: | Dropweight impact tests have been performed on thin CFRP panels stiffened with blade or T-stiffeners and comparisons made with similar plain panels. The change in structural response of the panels is governed by the amount of damage sustained during impact. The increase in panel stiffness is associated with the suppression of backface cracking but larger areas of delamination. |
