Abstract:

F Boron Fiber-Reinforced Aluminum 2024 as Detected by Acoustic Emission.Final technical rept.,FGrenis,Albert F. Rudy,Francis J.

Since the stress-strain relationship for the composite before fracture was also recorded, it was possible to detect that region strain where significant fiber fracture began for a particular composite specimen. Emphasis was on the study of the characteristics of fiber fracture rather than on determining the ultimate strength of the composite. Author
