Bio: Prof. John Mo is Professor of Manufacturing Engineering and formerly Head of Discipline of Manufacturing and Materials Engineering at RMIT University, Australia. The Discipline has 400 students, in which 150 students are postgraduate and PhD students. Prior to joining RMIT, he was Senior Principal Research Scientist in Commonwealth Scientific and Industrial Organisation (CSIRO), the Australian government research agency. He led research teams with 20 researchers working on many large scale government and industry sponsored projects including electricity market simulation, infrastructure protection, wireless communication, fault detection and operations scheduling. In particular, the fault detection and diagnosis projects have continued from CSIRO to RMIT. The research outcomes have been incorporated into many CNC machine controls to ensure smooth and faultless operations due to complexity and sophistication of this type of machine tools.

Speech Title: Engineering systems fault prediction
Abstract: Modern engineering systems are complex and sophisticated. Any minor issue can be escalated to complete system failure. With Industry 4.0, enormous amount of information can be collected from system processes online - the commonly knonw health monitoring paradigm. The idea is to maintain the system in good operating state. To achieve this goal, many researchers have contributed their efforts using digital signal processing. However, most researches are focused on recognition of fault conditions only. This means by the time when a fault is recognised, at least one problem has surfaced affecting performance of the system. This is not ideal for systems that requires absolute reliability in continuous operation mode. One of the difficult issues in health monitoring is prevention of faults. Faults are abrupt deterioration of the machine’s capabilities leaving the machine operator almost no time to take remedial action preventing rejects or causing damage to the machine. Detection of this type of machinery faults requires instantaneous machine signal discrimination. Therefore, health monitoring assumes that the system deteriorates over time (but still performing satisfactorily) so that continuous monitoring of certain operating parameters of the system will be able to detect problems before they occur. Therefore, the ability to continuously measure and process signals from the system to check its status is pre-requisite to health monitoring. A good example is monitoring wear and tear on cutting tools. The idea is to monitor certain conditions on the system by some indicative measures based on theoretical model of the operation so that decision to stop and repair can be made before the cutting tool malfunctions. This paper reviews a range of methods of fault prognosis and explains the development of a new system health condition indicator, Sum Standard Deviation Frequency. This indicator is computed from a new computational process that segments raw data streams into time segments and the segments are synchrosqueezed continuous wavelet transformed. So long as sufficient data is available, the mothod does not link to any application context information of the raw signal data stream hence making it context independent. More importantly, the trend that the system is going into faulty state can be monitored so that while the performance is deteriorating and the system is still working within acceptable conditions, preparation for providing the right repair can be made and the system can be stopped before producing bad outcomes.

Speech Title: Manufacturing approaches for multi-material hybrid composites
Abstract: Manufacturing of polymer composites is a field of incredible creativity. There is a wide range of processing solutions tailored to the requirements of performance, cost, and functionality. With the innovations in fibre deposition, steering, hybridisation, and forming the composite structures become increasingly more efficient and find new applications featuring challenging geometries and service conditions. In this talk we will discuss some of the new directions, where the composite properties can be boosted even further through emerging manufacturing concepts that bring together various materials in one interconnected system. Driven by the requirements of sustainability and efficiency, the concepts such as Multi-Matrix Continuously-Reinforced Composites (MMCRC) have been recently introduced. The concept allow designing and mapping the zones of different functions within one structure. The presentation will cover successful examples of MMCRC, examine implications of using these materials, and discuss their new features.

Speech Title: Building the Future: Innovation in Green Sandwich Structures for Construction Excellence
Abstract: This study explores three sandwich structures utilizing Formica sheets and perlite/sodium silicate foam as the core, with or without a paper honeycomb. By employing three-point bending tests and Lee's thermal conductivity apparatus, we assessed flexural characteristics and thermal conductivity. The results showcased a remarkable enhancement in flexural properties, including core shear stress and energy absorption, with the incorporation of paper honeycomb reinforcement. Thermal conductivity and flexural properties of these structures proved highly compatible with existing building materials, as described in relevant literature. Failure analysis revealed premature core buckling in paper honeycomb-reinforced sandwiches, contrasting with the ability of foam-filled honeycomb core sandwiches to sustain higher loads, exhibiting core shear failure, skin rupture, and delamination. Foam-filled paper honeycomb structures emerged as capable of withstanding higher bending loads, presenting promising applications as eco-friendly materials for building thermal insulation.
