Effect of raster orientation on pure nylon, carbon fibre nylon, and glass fibre nylon using three-dimensional printing

Abstract

In this study, pure Nylon 6 is taken for investigation and printed in fused deposition modelling, with short carbon fibre, and short glass fibre as reinforcements. The material behaviour under static and dynamic thermal analysis was measured. The specimens were three-dimensional printed as per ASTM standards, and their mechanical behaviour was analysed. According to the findings, a short carbon fibre-printed specimen results in a maximum tensile strength of about 76% and a flexural strength of 89%. Virgin nylon results in the highest impact properties, showing that adding short fibre reduces the impact strength. The dynamic thermal analysis of virgin nylon, short carbon fibre, and short glass fibre results reveals that carbon fibre nylon increases storage modulus, whereas glass fibre nylon increases loss modulus. The nylon reinforced with short carbon fibre results show improved behaviour under static and dynamic thermal conditions.
