Effect of low-velocity impact damage to the mechanical properties of glass fiber/keratin filler sandwiched thermosets composite / Khairunnisa Liyana Abdul Hamid Ridza

This research study on the mechanical and physical properties of low-velocity damage keratin filled/glass fiber sandwiched composite. In this research, fiber filler used is the pulverised chicken feather which varies at 10%, 20%, 30%, 40% and 50% by weight. The chicken feather composite then laminat...
