Analogy of thermal properties of polyamide 6 reinforced with glass fiber and glass beads through FDM process 2019-28-0137
The essential target of this examination is to compare the thermal properties of two different polyamide composite blends with inventive thermal properties. The two combination of specimen was prepared by using polyamide-6 (PA6) reinforced with 10, 20 and 30 wt% glass fiber (GF) and glass beads (GB) respectively and these composite blends were extruded in form of wire through twin screw extrusion process. The experimental study illustrates to print the specimens by means of a commercial FDM three dimensional (3D) printer. The measure the responses like morphology, thermal conductivity and heat distortion temperature of composites was observed. The results associate that SEM morphology shows high dense homogeneous distribution and fine arrangement of particles in the printed samples. Moreover it reveals that increasing thermal properties of the printed specimen like TC and HDT with the enhancement of 30% glass fiber and bead content in PA6 composites than lower weight percentage composites. The glass fibers are highly crystalline material that can even improve the thermal properties of the polymer matrix and the glass beads are dimensionally stable material that can provide high modulus to the polymer matrix. Further, it was observed that, thermal property of the composites increased because of high melting point and highly bonded composites through 3D printed, it may opens a new avenues for applications like automotive, aerospace and electronics components.
