Fiber breakage

Definition

Fiber breakage refers to the failure of individual fibers within a composite material, leading to a loss of structural integrity. This phenomenon can be detected through acoustic emissions, which are sounds produced when the fibers break, and are significant for evaluating the health and performance of materials under stress.
