This study presents a sequentially coupled optimisation of structural topology and fibre orientation for 3D printing continuous carbon reinforced polymer composites. Topology was first performed to obtain the geometry structure under specific load, then fibres were placed along identified principal stress trajectories. Composite preforms printed by material extrusion-based technique followed post-processing with vacuum bagging using epoxy infusion. The case Messerschmitt-Bolkow-Blohm (MBB)...
Particle-fluid flows with free-surfaces are commonly encountered in many industrial processes, such as wet ball milling, slurry transport and mixing. Accurate prediction of particle behaviors these systems is critical to establish fundamental understandings the however presence free-surface makes modelling them a challenge for most traditional, continuum, multi-phase methodologies. Coupling smoothed hydrodynamics discrete element method (SPH-DEM) has potential be an effective numerical...
This paper presents an experimental study on 3D printing of continuous carbon fibre reinforced thermoset epoxy composites. Powder-based solid was electrostatically flocked the 1K tow and then melted to fabricate composite filaments. The produced filament printed using a modified extrusion-based printer which deposited following designed paths, form multilayer preforms with complex geometries. After vacuum bagging oven curing, high tensile strength (1372.4 MPa) modulus (98.2 GPa) were...
This study investigates the mechanism of fibre deposition in conventional 3D printing and presents an aligned (AFD) method to improve placement. The reveals that cracking filament transition zone torsional deformation during steering path are main cause defects process. AFD is shown reduce mitigate waviness twisting, hence producing smooth deformation, introducing less air voids breakage printing. It found improves alignment angle from ±25° ±12° reduces void content 0.27 % straight-line...
Polyphenylene sulphide composites with recycled carbon fibres are of high interest due to their promising mechanical properties. Poor interface adhesion between fibre and thermoplastic matrix, however, remains a major problem in composite manufacturing. Herein, novel one-step method using bio-inspired copolymerisation dopamine graft silica nanoparticles onto the surface is reported. Comprehensive investigations were conducted fabricate treated characterise modified samples by analysing...
This study presents a data-driven, probability embedded approach for the failure prediction of IM7/8552 unidirectional carbon fibre reinforced polymer (CFRP) composite materials under biaxial stress states based on micromechanical modelling and artificial neural networks (ANNs). High-fidelity 3D representative volume element (RVE) finite models were used generation points. Fibre friction between fibres matrix after fibre/matrix debonding taken into consideration implemented as VUMAT...
