Faculty

Professor Singh has over eight years of research experience in national and international institutions. He completed his PhD in fibre-reinforced polymer composites. For five years, Professor Singh worked on a project sponsored by a US Army research laboratory focused on developing cold spray as an additive manufacturing and repair technology for polymers. Professor Singh was also sponsored by the New Jersey Economic Development Authority to develop technology for the quick, on-site repair and metallisation of fibre-reinforced polymer composite materials used in offshore wind energy farms. During his research journey, Professor Singh has also supervised various graduate student theses and undergraduate student projects.

During his PhD, Professor Singh designed and fabricated symmetric and asymmetric fibre-reinforced polymer laminates with improved impact resistance compared to similar laminates with different stacking sequences. The impact resistance of these laminates was further enhanced by using MWCNTs as secondary reinforcement. This work demonstrated the ability to customise material properties to meet specific requirements.

After completing his PhD, Professor Singh worked on developing the state-of-the-art application of cold spray as an additive manufacturing and coating technology for polymer and fibre-reinforced polymer composite materials. This work was sponsored by the Army Research Laboratory, USA. Professor Singh was also sponsored by New Jersey Economic Development Authority (NJEDA) to develop rapid, on-site repair and metallisation technology using cold spray for fibre-reinforced polymer composite structures.

Professor Singh has published on the design, fabrication, and characterisation of metamaterials inspired by biological and origami structures.
