Abstract
This study investigates the puncture resistance behaviors of architectural coated fabric. The effects of boundary condition, penetrator shape, yarns angle, puncture rate, weight percentage of fiber and coating on puncture resistance behaviors of coated fabric are studied. A fast and effective method is introduced to model the nonlinear anisotropic mechanical behavior of coated fabric. Findings indicate that puncture resistance performance of coated fabric is the critical dependent of the magnitude of penetrator shapes. The essence of penetrator shapes influence is the number of yarns contacted with the bottom of penetrator. The yarn angle in the interest region affects the puncture resistance performance of the coated fabric, which is mainly related to the effective length of the yarn. Besides, the coating weakens the resistance performance when the shape of the penetrator is conical. The puncture resistance strength increases with the increase of weight percentage of fiber. The FE models provided a reasonable prediction of the puncture resistance behavior of the coated fabric.
