Experimental Investigation of the Tensile and Impact Properties of Twill and Twill Derivative Woven Fabric Reinforced Composites

Abstract

In recent years the use of woven composites in structural applications has increased rapidly due to the advantages it offers such as easy handling, dimensional stability, deep drawing shape-ability, enhanced toughness and increased impact resistance. Mechanical properties in textile composites are closely connected with the textile reinforcement's internal structure. This paper reports and discusses a study of the tensile and impact properties of the twill and twill derivative woven fabric reinforced composites. Tensile strength, modulus of elasticity and elongation at break values of the composites were found by tensile tests. In addition impact tests are performed on specimens of woven fabric reinforced composite laminates in order to measure impact strength and characterize damage mechanisms at diverse impact energies. The experimental results reveal that the average float length and weave interlacing coefficient, which are determined by weave pattern, significantly affect the tensile and impact properties of the composites. It is observed that 3/1 twill woven fabric reinforced composite showed the best performance in tensile tests along warp and weft directions. It is also observed that 3/1 twill woven fabric reinforced composite has the lowest impact strengths at the highest deflections; whereas, 3/3 twill woven fabric reinforced composite has the highest impact strengths at the lowest deflections.

Effect of pattern on air permeability, mechanical resistance and thickness of wovens

“…Weave repeats are square weaves for all woven patterns but not for warp rib. This means that yarn interlacing is similar for warp and weft direction in fabrics with square weave repeats but different in fabric with warp rib pattern [20]. Yarn interlacing and weave repeats for patterns are illustrated in Figure 3.…”

“…But yarn length between two consecutive yarns in same direction differs due to pattern effect so average yarn floats for patterns and other structural properties for fabrics should be determined. Average yarn floats for warp and weft yarns were calculated according to Ashenhurst theory by the following formula [20]:…”

Study on tensile strain of carbon fiber triaxial woven fabric/thermoplastic polyurethane flexible textile composites

“…Ming et al 13 examined how fiber sliding and shear deformation in the fabric affects drape properties by hemispherical preforming experiments. Özdemir et al [14][15][16][17] conducted static and dynamic experiments on fabrics with different structural reinforcements and weaving patterns, and they found significant variations in stability and mechanical performance of fabrics and composites based on different structures. At present, the main research objects are woven fabrics or membrane material.…”

Analysing The Effects of Knitted Fabrics Physical Properties to The Heating of Sewing Machine Needles

“…The needle heating can lead problems for productivity and seam quality such as sewing thread breaks, creased threads, seam damage, fabric damage and decrease of production [6][7][8][9][10][11][12][13].…”
