报告题目：Multifunctional 3D Woven and Z-pinned Composites
报告人：Dr. Raj Ladani（Royal Melbourne Institute of Technology University）
Advanced fibre-reinforced polymer composites are now extensively used in aerospace industry, as a result of the increasing demand for lightweighting technology. However, in the absence of through-thickness reinforcement, laminated composite materials are susceptible to interlaminar and intralaminar delamination damage. In light of these challenges, this talk focuses on the research in to the effects of using through-the-thickness reinforcement including 3D weaving and z-pinning on the interlaminar delamination resistance of fibre composites. This research explores key parameters for improving the fracture toughness and electrical properties of fibre composites with through-thickness reinforcements, including the effects of z-binder materials (thermoplastic, metallic and structural fibre), and their volume fraction and architecture (weaving and pinning) on improving the fracture properties, electrical conductivity and self-healing functionality. The research further demonstrates the use of finite element modelling techniques to design 3D reinforced composites.
Dr. Raj Ladani graduated with a Bachelor of Aerospace Engineering from RMIT University, Australia in 2012. Dr. Ladani completed his doctoral degree in Aerospace Engineering at RMIT University’s Sir Lawrence Wackett Aerospace Research Centre in 2016, with a research focus on nano-reinforced multifunctional fibre composites. Dr. Ladani has since published over 17 journal articles in top quartile journals on fracture, fatigue, damage detection, and multifunctional properties of nanocomposites and fibre composites. Dr. Ladani is a co-investigator in the Australian Research Council’s Linkage Grant on “Multifunctional 3D Reinforced Composites” (2016-2019). At RMIT University, Dr. Ladani is a course co-ordinator and lecturer in the Aerospace and Aviation discipline, teaching Aerospace Design for Manufacturing and Assembly. Dr. Ladani is currently visiting NUAA as part of the joint NUAA-RMIT laboratory initiative.
