Notched impact strength of fibre - reinforced polymer (FRP) composites / Azlira Abdul Aziz

This project is attempted to apply mechanics concepts for notched fiber reinforced polymer (FRP) composites material where it has subjected to low impact loading. The materials used were Woven E-Glass fiber / epoxy composites. The specimen configuration for this project was 50 x 200 mm and notched l...
