Abstract

This project aims at experimentally studying low velocity impact on fiber reinforced glass sheets. An experimental setup is fabricated, wherein a dart of known mass with accelerometer inbuilt in it made to fall on specimens of fiber reinforced glass sheets. The damage of the sheets of various thicknesses for various kinetic energies of dart is studied. The kinetic energy is varied by altering the height of the dart above the specimen sheet. The amount of energy transferred from the dart to the sheet is measured by the accelerometer output. The kinetic energy of the dart just before the moment it strikes the sheet is calculated by simple formula. The energy absorbed by the sheet is proportional to the thickness, material characteristics and the kinetic energy of the dart during collision. The dart is made fall free on the sheet; therefore, the acceleration is constant and is equal to the acceleration due to gravity constant ($9.8 \text{ m s}^{-2}$). Since the height of the dart above the sheet does not exceed three meters, the velocity during collision is comparatively low. A tabulation of velocities of dart, thickness of sheets and obtained. The accelerometer's electrical output is signal conditioned and is displayed in a computed using appropriate software. The goal of this project is to get a complete knowledge of the low velocity impact on the glass reinforced fiber sheets and to conclude how feasible it can be for various applications.
