	abstract = {This study investigated the fabric resistance of three-dimensional (3D) woven fibreglass composites generated by
impactors of three shapes, i.e., hemispherical, conical, and ogival, on four types of composite structures. Composites
were fabricated using the hand lay-up technique. Crimp and mechanical impact resistance tests were carried out in
accordance with ASTM D2444 standards and ASTM D3883-04, respectively. The four-floating interlocked (4FLL) yielded
the strongest fabric damage tolerance for all the three types of impactors’ shapes with 6.3 kN for the hemispherical
shape, 4 kN for the conically shaped, and 3.8 kN for the ogival shape. Additionally, the 4FLL generated a fabric crimp
of 3.5\% and 2.8\% on both fabric directions. The post-impact damage showed that the ogival shape impactor penetrated
samples of woven composites better than the conical and hemispherical shapes.},
