Failure analysis of notched graphite-epoxy tubes
Notched unidirectional graphite/epoxy tubes with fiber orientations of 2.5°, 15°, 45°, and 87.5° were failed in tension, compression, torsion, and combined compression-torsion loading. The stress field around the slot-like notches, aligned with the tube axis, was determined using an infinite flat …

Fatigue response of notched graphite--epoxy laminates
… and strength of notched quasi-isotropic graphite-epoxy laminates were recorded and related to the fatigue damage. Two different laminates [0,90,+45,-45]s (type A) and [ +45, 90, -45, 0] s (type B) were considered and the effects of stacking sequence were compared. Nondestructive testing …

Energy Absorption Capacity of Graphite-Epoxy Composite Tubes
… composite tubes fabricated from high tow count graphite fiber is compared with those of similar tubes fabricated from aerospace-grade fiber to determine the viability of considering the use of such fibers in automotive applications. To that end, graphite-epoxy tubular specimens with circular and …
