paper reports and discusses a study of the tensile and impact properties of the
twill and twill derivative woven fabric reinforced composites. Tensile
strength, modulus of elasticity and elongation at break values of the
composites were found by tensile tests. In addition impact tests are performed on specimens of woven fabric
reinforced composite laminates in order to measure impact strength and
characterize damage mechanisms at diverse impact energies. The experimental results reveal
that the average float length and weave interlacing coefficient, which are
determined by weave pattern, significantly
affect the tensile and impact properties of the composites. It is observed that
3/1 twill woven fabric reinforced composite showed the best performance in
tensile tests along warp and weft directions. It is also observed that 3/1 twill woven fabric
reinforced composite has the lowest impact strengths at the highest
deflections; whereas, 3/3 twill woven fabric reinforced composite has the
highest impact strengths at the lowest deflections. </span>}, number={4}, publisher={Ege University}
