Abstract
This paper presents an investigation of the effects of test specimen geometries and load ing conditions of different stacking sequences on the fracture behaviour of carbon/epoxy laminates with damage consideration. The specimen geometries chosen are single edge notched (SEN), double edge notched (DEN), centre notched (CN), three point bending (TPB) and compact tension (CT) specimen while the stacking sequences are [0] s, [0/90] s, [03/902]s, [90/0/±45]s, [±45], and [90]s. The development of damage within the test pieces were monitored using acoustic emission, COD measurement, optical microscopy and scanning electron microscopy (SEM). These experimental methods are shown to be capable of assessing the development of damage and characterizing fracture behaviour of carbon/epoxy composites under consideration.
