Tensile characteristics of sisal and polypropylene fibre non-woven materials for geo-textile applications

Abstract

The objective of this study is to analyse the cross direction tensile properties of composite non-woven fabrics. Three different blend proportion, that is, 20% sisal/80% polypropylene, 80% sisal/20% polypropylene and 50% sisal/50% polypropylene were used to study the tensile properties of the composite non-woven fabrics. Box–Behnken design has been used with three parameters namely, punch density, depth of needle penetration and mass per unit area. The samples produced were subjected to calendaring at 145℃ temperature and 6.12 kg/cm2 pressure. The tensile strength of tested fabrics has been analysed in detail and it has been found that 20% sisal/80% polypropylene composite non-woven fabric is performing better than other blends.

Mechanical behavior of flax/polypropylene commingled nonwoven at dry scale: Influence of process parameters

“…Figure 6 shows the maximum loads (Fmax) and the strains at break for all nonwoven specimens during tensile tests in the two directions (MD and CD). Regarding the tensile behavior of the NW-A set, increasing the material surface density generates an increase in the tensile load in the MD and the CD, which can be verified by the previous work presented by Xue et al 13 and Ilango et al 35 However, this increase of material surface density involves a decrease in the strain at break in the MD, while the strain at break remains quasi constant in the CD. The anisotropy can be observed clearly for the NW-A set fabrics.…”

“…[29][30][31][32][33][34] Previous works have focused on the influence of the needle-punching density on the mechanical properties of composite structures, but few papers have focused on the influence of these parameters on the mechanical behavior at the dry fabric stage. In a very recent paper 35 on sisal and PP fiber nonwoven materials, the influence of the process parameters on the mechanical behavior at the dry fabric stage has been described, but only on the CD tensile properties; the anisotropy effects have not been analyzed. Consequently, the purpose of this paper is to analyze the mechanical behavior of flax/PP commingled nonwoven fabrics by tensile and flexural tests conducted at the dry stage, before the hot molding process.…”

Mechanical behavior of PVDF membrane based on the uni-/bi-axial loading experiments

“…Some other publications about the mechanical properties of textiles via a theoretical approach have been investigated. [20][21][22] Li etal. 23 have studied the central tearing behavior of PVDF.…”
