Mechanical Behaviour of Carbon Fibre Reinforced PLA (CFRP) Manufactured Using Fused Deposition Modelling Technique

Abstract

Rapid prototyping (RP) technology is creating a physical model in layer by layer manner immediately from their CAD without the use of any tool, Dies and Fixture. Rapid prototyping, in Comparison to traditional processes, can readily and quickly build complicated parts, also reduces time & overall product development cost. Early detection and mitigation of design errors are aides by RP. The percentage of infill material Layer Thickness and specimen orientation were all modified in this investigation. The thickness of the layers was varied between 0.1mm, 0.2mm and 0.3mm about the horizontal plane, the orientation parameters were changed to 00, 450, 900. A total of 9 trials were chosen for testing using Taguchi's Design of Experimental Method for L9 orthogonal array of three parameters with three distinct levels from 27 experiments. The best tensile strength was obtained for a specimen with CFRP material of 0.2mm layer thickness, 60% infill, 00 orientation.
