Abstract
Studies were conducted to observe the effect of fracture toughness and damping response on
fabric reinforced epoxy polymer composites. The samples of glass fabric, kevlar fabric and
carbon fabric having 15wt%, 25wt%, 35wt%, 45wt% and 55wt % fabric content were prepared
and tested following ASTM standards. Fracture toughness, peak load and increase in energy
absorption are determined for the fabric-epoxy composites. Effect of temperature on storage
modulus, loss modulus and tan delta values for various percentages of fabric epoxy composites
are noticed and corresponding damping response behaviour is determined. The results revealed
that reduction in strength at higher percentage of fabric content is due to improper bonding
between fabric and epoxy resin. Higher peak load values and increased values of energy absorption
are observed at lower percentage of fabric content. Kevlar fabric proves to be beneficial for
specific energy absorption capability. Strength retention capability at higher temperature is far
better for carbon fabric epoxy combinations. Composites with lower fabric content retain much
higher temperature and peak load. Also the experimental findings are in close proximity with
that of theoretical results.
