Notched strength of fiber-reinforced polymer (FRP) / Norhazwan Norizan

This project involved in the study of notched strength reduction and determination of damage zone, aₒ, of E-glass, Kevlar and Carbon Fiber/Epoxy composite laminates. The specimen configuration used for this project was 101.6 mmx 101.6 mm with 30 mm diameter central hole and was subjected to bi-axial...
