Static, Ballistic, and Impact Behavior of Glass/Graphite Drive Shafting

Abstract

Limited static tests on damaged scale-model Heavy Lift Helicopter (HLH) plus or minus 45 degree glass/plus or minus 5 degree graphite drive shaft sections at 150 deg F indicated that the shafts are not capable of meeting the design requirement of the HLH. Low-energy impacts (ball drops) produced catastrophic brittle failure of the graphite material. Ballistic damage was localized to the impact area but resulted in a strength reduction factor of approximately 1.75.
