investigation of Damage Progression in CFRP with a Variety of Fiber-Resin Combinations by Acoustic Energy MeasurementsUltimate stress or strain values obtained by static tests on CFRP yield no information about the onset of severe damage progression. With respect to an optimal utilization of this light-weight material, however, ist would be useful to know the strain value where catastrophic damage propagation begins. Acoustic emission (AE) analysis is an appropriate technique for the characterization of damage progression, since even weak alterations in the material occurring in an early stage of loading may be detected. The energy is the most important AE parameter measured. The significance of accumulated AE energy, correlated with strain, is superior to that of common event or count evaluations. Five types of fibers where combined with two epoxy resins and four bismaleimides. The influence of fiberhesin-composition was investigated using ring specimens with unidirectional fiber orientation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
