Experimental Study on the Mechanical Behavior of Polyamide 6 with Glass Fiber Composites Fabricated through Fused Deposition Modeling Process

In this paper, experimental studies were conducted to examine the mechanical behavior of a polymer composite material called polyamide with glass fiber (PA6-GF), which was fabricated using the three-dimensional (3D) fusion deposition modeling (FDM) technique. FDM is one of the most well-liked low-cost 3D printing techniques for facilitating the adhesion and hot melting of thermoplastic materials. PA6 exhibits an exceptionally significant overall performance in the families of engineering thermoplastic polymer materials. By using twin-screw extrusion, a PA6-GF mixed particles made of PA6 and 20% glass fiber was produced as filament. Based on literature review, the samples have been fabricated for tensile, hardness, and flexural with different layer thickness of 0.08 mm, 0.16 mm, and 0.24 mm, respectively. The composite PA6-GF behavior is characterized through an experimental test employing a variety of test samples made in the x and z axes. The mechanical and physical characteristics of PA6-GF polymer were examined using tensile, flexural, and impact tests. The best outcomes were obtained for specimens printed with 0.08 mm lower value of layer height, which had a greater impact on all mechanical performance. The replacement of traditional materials was suggested with this high-strength printed samples in industrial application products.
