Centre for Natural Material Innovation
Dr Darshil Shah is a composites engineer who specialises in natural materials science and technology. Within the Centre for Natural Material Innovation at Cambridge University, Darshil is working with scientists across various disciplines (including biochemists, plant scientists, chemists, architects, engineers, and fluid dynamicists) on developing engineered wood and bamboo composites, as low-embodied energy replacement materials to steel and reinforced concrete, for the construction of skyscrapers.
Darshil obtained his PhD in Mechanical Engineering from the University of Nottingham in 2013, on the topic of developing plant fibre biocomposites as sustainable and functional alternatives to traditional glass fibre composites for wind energy applications. Before working at Cambridge, he was a PDRA at Oxford University’s Silk Group for two years, developing animal silk-based polymer composites for high-toughness components. Working at the zoology department at Oxford also enabled him to study various other natural materials (such as ivory) from a materials science as well as a biological/evolutionary perspective.
Darshil's research is in the field of light-weight sustainable materials. Briefly, his work principally aims to i) fundamentally understand structure-property relations in natural materials (at the micro/meso/macro scale), which often are hierarchical, multifunctional composites, and ii) investigate the potential of their usage in conventional and innovative engineering components, often requiring thorough characterisation, optimisation and development studies and undertaking comparative case-studies. Combining sustainability with performance (including reliability/durability) in natural materials is a major focus of his research.
Darshil's high-impact research has received numerous distinguished awards, including the International Quadrant Award 2015 for outstanding scientific works in the field of engineering and high-performance plastics and composites, and the JEC Asia 2013 Innovation Award for the world’s first functional flax composite wind turbine blade.
