Department of Textile Technology of Dr B R Ambedkar National Institute of Technology Jalandhar proposes establishing a 3-Dimensional (3D) textile structures manufacturing machine having novel shedding mechanism and multiple weft insertions. The glass and carbon yarn preforms are currently developed using conventional weaving technologies and the weave structures commercially produced are 2-Dimensional (2D) structures such as plain weave, twill weave, satin weave, etc. However, 3D solid structures are not produced commercially, owing to low production rate. These commercially developed 2D fabrics are laminated to produce composites. The delamination is one of the major cause of failure of the composite structures. Compared to 2D laminates, the integrally woven 3D textile structures have very high delamination resistance, very high tensile strain to failure values, tailored through thickness properties, they have high impact energy absorption capability. The proposed shedding mechanism is based on the principle of minimising unnecessary movements of yarns due to shedding during weaving process. In the case of 3D solid structure weaving on conventional weaving machine, the number of wefts inserted at fell of the cloth are equal to number of stuffer yarns plus one. Thus for four stuffer 3D orthogonal structure, the five wefts will be inserted at fell of the cloth.
