Abstract
This manuscript presents the projectile impact behavior of hybrid jute/epoxy composite laminates using an instrumented air gun impact setup with the projectile moving in the vertical direction. An approach based on the stiffness change is used to predict the projectile impact response of hybrid jute epoxy-filled laminates impacted with a stainless-steel projectile. The experimental validation of the parameters like dynamic hardness (Hd) coefficient of restitution (COR), natural frequency, damping factor, and loss factor was used to analyze the impact behavior of jute/epoxy composites strengthened with fillers ZrO2, ZnO, and TiO2. The free vibration tests of the pre-and post-impacted filled hybrid composites give the natural frequency and damping characteristics at room temperature and subzero temperatures. The results show that the stiffness of the laminates increases with the increase of Hd and COR. The natural frequency of the composite laminates was lower for the laminates subjected to higher velocity impact compared to the laminates subjected to the lower impact velocity. The analysis of the damping factor and loss factor shows that damping was better at subzero temperatures compared to room temperature.Keywords
