摘要

Interlayer friction is an important factor in producing rolls of glass-fiber woven fabric and strongly depends on the fabric structure and fabric interlayer contact mechanism. This paper investigates the effect of the initial contact state on the fabric/fabric friction coefficient by adjusting dislocations along circumferential and axial directions with a Capstan-based test setup. Results reveal that the maximal friction coefficient is approximately proportional to the height gradient between two adjacent yarns, while the minimal friction coefficient is less sensitive to the fabric structure. Moreover, a dislocation between fabric layers reduces both the maximal static and dynamical friction coefficients, and actively reciprocating a dislocation along the axial direction is an effective way of avoiding the interlayer friction from remaining at a low level. A dislocating mechanism is developed and introduced to a commercial fabric winding machine to verify the effectiveness of the proposed method in improving winding quality.
