Paper Abstract
In this paper, the Acoustic emission (AE) technique is applied to clarify the damage mechanisms of 3-D carbon/epoxy
braided composites with different braiding angles under the compressive loading. The AE responses for the three kinds
of specimens are significantly different due to the different damage mechanisms. The results reveal that the curves of
cumulative AE counts can be used to analyze the damage processes of 3-D braided composites more exactly than that of
only using the load-time curves. Through analyzing both the cumulative AE counts and the load-time curves at the same
time, the damage processes can be divided into different stages and be described in detail. The present paper reveals that
the AE technique is a viable and effective tool for analyzing the fracture process and damage mechanisms in the 3-D
braided composite materials under the compressive testing.
