Analysis of the mechanical properties of woven and nonwoven fabrics as an integral part of compound fabrics

In this paper the difference between the mechanical properties of woven and nonwoven fabrics is presented. and the important role of constructional parameters (particular the cover factor) of reinforcement fabric in the compound fabric is stressed. Some basic mechanical properties, such as tensile strength, elongation at break, work to rupture and the force by 1% of elongation were measured and analysed. The stress/strain diagrams show the differences in the behaviour under defined loads of different woven and nonwoven fabrics. The results show that the fabric with good mechanical properties is not always suitable as reinforcement, where the needle punching is used as a method of linking layers into compound fabric.
