High velocity impact response of rubber panel

This study presents the response of rubber panel under high velocity impact. High velocity impact tests areperformed on the rubber panels and impact resistance is investigated. The ballistic limit and residual velocity of samplesare measured. Natural rubber is vulcanized, a process by which the rubber is heated and sulfur, carbon black, Calciumcarbonate, Zinc oxide and volcacit are added. The mixing is carried out by two-roll mixing mill to produce a uniformproduct. The cure characteristics of composition are investigated by using rheometer and the samples are prepared atthe appropriate temperature and pressure. Samples are limited to all 4 sides constrained completely in fixture and areshot by a hemispherical projectile. Due to the viscoelastic and damping properties of rubber, it is an appropriate choicefor blast protection and impact absorption.
