Numerical Investigation of 3D Printed Fibre Reinforced Composites under Tensile Loading Condition

Dr Taasnim Ahmed Himika's research delivers a significant advancement in additive manufacturing of continuous fibre-reinforced composites through rigorous numerical investigation of fibre orientation, nozzle geometry, and extrudate stacking sequence. By explicitly modelling extrudate cross-sections and process-induced voids, her research investigated manufacturing parameters, tensile strength, and energy absorption. It was found that using square nozzles with a regular stacking sequence could achieve near-conventional composite strength, while a staggered sequence maximises energy absorption. These outcomes will guide structural design decisions across several industries, such as defence, automotive, aerospace, and construction sectors, and contribute to the continued growth of the $46 billion global additive manufacturing industry, strengthening Australia's economic and technological competitiveness.
