Abstract

An attempt is made to investigate the feasibility of Fused Deposition Modeling (FDM) using Acrylonitrile Butadiene Styrene (ABS) polymer material reinforced with composite layers to additive manufacture textiles for stab–resistant application. The purpose of this study is to investigate the relationship between the cross-sectional design of textiles and their protective performance. This paper presents finite element analysis of a planar CAD model and five additive manufactured textiles with different overlapped scale-linked design features that were created through a CAD system and simulated by a test blade using ANSYS software. Acrylonitrile Butadiene Styrene (ABS) polymer was applied to all the test samples in simulation testing, whereas, the specification of test blade was taken from NIJ Standard-0115.00. Result shows the knife penetration through the planar model was much larger than the scale-linked textile models. The overlapping feature of textile models had restricted the penetration of knife. However, Model 5 was the most suitable design for stab protection among the textile models and maximum total deformation distributed on its body was the lowest compared to other designs.
