Learning from nature: biomimetic approach for a new generation of Advanced Armoured Composite Materials
Over the last two decades, composite materials have changed the world of industry, reshaping several industrial sectors including aerospace, automotive and energy. Due to their unique strength to weight ratio, these materials have allowed for the development of new lightweight aircrafts and automobiles characterised by high mechanical properties, lower fuel consumption and reduced CO2 emissions. However, the expansion of these materials into armoured systems and protective structures is, to this date, still hindered by their weak resistance against impact events given by their intrinsic layered nature, which makes them susceptible to catastrophic failures due to their brittle behaviour. To overcome these limitations, an interesting approach is to take inspiration from nature, starting from the consideration that the efficiency of natural materials rises from the double necessity of supporting life while offering protection from the external environment.
This project aims at analysing the relationships between biological systems and advanced composites materials, taking inspiration from natural impact-resistant structures in order to develop new armoured laminates capable to withstand shock loads in the out-of-plane direction. The project will investigate new geometries and three-dimensional arrangements of specific plants, crustacean cuticles and sponges, and analyse hybrid structures such as natural fibres and mollusc shells to derive new design principles and manufacturing processes for a new generation of advanced composite systems. During the project, the successful candidate will work in a friendly and multi-disciplinary environment, working on the design, manufacturing and mechanical characterisation (destructive and non-destructive tests) of novel composite structures and armour materials.
The outcomes of this project will lead to applications into aerospace (leading edges and radome), railways (boogies and underframe) and defence applications (body armours and blast resistant panels) expanding the use of composite systems into new fields while pushing their limits to face new exciting challenges such as multifunctional systems and responsive materials.
As part of this PhD, the successful candidate will investigate several aspects of advanced composites and biological structures such as:
- failure mechanisms of modern composite laminates
- structural behaviour of natural systems under different loading conditions
- non-structural behaviour of multifunctional composites (autonomous structural health monitoring, morphing, folding)
- mechanical characterisation of advanced materials
- Finite Element analysis of composites
What will you learn during this PhD?
- to analyse and design advanced composite structures based on biomimicry principles
- to manufacture hybrid composite laminates with advanced methods and innovative processes
- to characterise the mechanical response of composite materials with both static and dynamic tests, investigating their behaviour and microstructure with both destructive and non-destructive tests
Successful applicants will ideally have graduated (or be due to graduate) with an undergraduate Masters first class degree and/or MSc distinction (or overseas equivalent). Any English language requirements must be met at the deadline for applications.
Essential Background: Material Science and Structural Engineering with some understanding of chemistry and composite materials’ principles.
