Abstract: Abstract: Due to the ballistic panel still need to be further improved to get better stabbing performances, in this project, compress moulding process was used to combine spacer fabric with UD fabrics and woven fabrics with different adhesives and the new composites were under quasi-static and impact testing to investigate its anti-stabbing performances. The results shows that firstly with a tighter fabric structure on the spacer fabric’s up and down layer, the anti-stabbing capability will increased apparently; secondly, the perpendicularly yarns in the middle of the spacer fabric can lock the edge of the knife efficiently to stop it going down continuously; and thirdly, with a stronger, higher tenacity and higher cohesive strength adhesive, the anti-stabbing performances can be improved accordingly.
