Abstract

The low-velocity impact properties of the developed two-dimensional multistitched/micro/nano E-glass/polyester woven composites were studied. It was observed that material type (silicate or carbon or metal), material particle size (nano or micro), amount of materials (weight, %), stitching density (step/cm) and stitching type (hand or machine) influenced the damaged areas of composites. The unstitched/nano and unstitched/micro E-glass/polyester woven composites had small damaged areas in the front face but they had large damaged areas in the back face. The multistitched structure had also a small damaged area in the front face; however, it had a very small damaged area in the back face. The results indicated that the multistitching suppressed the impact energy relatively at a small area. Therefore, the two-dimensional multistitched and multistitched/nano E-glass/polyester woven composite structures showed a better damage resistance performance compared to those of the unstitched or unstitched/nano composites.
