Investigation of multi-layered woven car seatbelts with optimum performance

This work was aimed to study the mechanical properties of multilayered woven automobile seatbelt by varying the weave design, fabric density and material. Three layered woven webs were produced in three different weaves (twill, matt and combination of plain and matt named here as "combo"). The webs were produced either in polyester, Polyamide (Nylon) or by using combination of both. The seatbelts produced in matt weave were able to bear more load before rupture as compared to twill and combo weaves. The effect of actual thread density and fabric areal densityon the breaking strength of seatbelt was found. Finally, a low cost seat belt having minimum fabric areal density and optimum strength was proposed.
