Designing lightweight aircraft parts to improve fuel efficiency is crucial to meet the aviation sector’s goals of reducing CO2 emissions. However, it is also important to ensure that these lightweight parts have a lower CO2 footprint over their entire lifetime. Previous studies have successfully achieved this using topology optimization and low...

Structural design for unconventional aircraft can be quite challenging and could undergo<br/>many iterations until a solution is found for all load-cases such as static sizing, stability and<br/>crashworthiness. Ultimately, all of the design aspect are integrated in the earliest design<br/>changes for which Topology Optimization (TO) could...

Throughout history, human progress has been defined by the mastery of materials, transitioning from stone and bronze to the steel age. However, this progression has not only been defined by the materials utilized but has also encompassed a shift in processes, moving from the industrial to the information era. Despite the advances in fabrication...

In this work, it is demonstrated that kirigami deformation behaviour can be controlled by tailoring the anisotropic material that is used to create the kirigami structure. The ultimate goal is to find a relationship between the material pattern and the deformation behaviour of the kirigami structure. An anisotropic thermoplastic polyurethane...

Liquid crystalline polymers have recently attracted attention for their great tensile properties. However, their interlaminar fracture toughness is low. To solve this, toughening approaches inspired by Nature are applied, exploiting the shaping freedom of fused deposition modelling. Three approaches are studied: the matchstick approach, z...

Mycelium based composites (MBC) have revolutionised the field of material production, where a living fungus is employed to overgrow and bind lignocellulosic substrate materials together. Their bio-based nature, low embodied energy, and biodegradability, mark their great potential to reduce the increasing pressure conventional materials put on...

Poor recyclability and high carbon footprint have presented a major hurdle to the adoption of thermoset composites . Natural fibre composites offer a reduced CO2 route to reinforcing fibres whilst recyclable epoxy chemistries might lead to reinforcement recovery at end-of-life. Here, short bamboo fiber reinforced epoxy composites are...

A structural supercapacitor (SSC) is a composite material that bears mechanical loads and stores energy, and its encapsulation method of the device is vital for scale-up. Here we present an SSC with an encapsulation interface consisting of spread-tow fabric electrodes and glass fabric encapsulators infused with epoxy resin. Through surface...

Kirigami- the Japanese art of paper cutting – is used extensively as a design philosophy for stretchable and morphable structures. An array of cuts on a thin planar sheet creates a structure that can morph into a 3D pattern on applying an in-plane uniaxial load. This type of structure is called a kirigami metasurface. A subset of this type of...

In the past two decades, there has been a substantial increase in the use of natural fibres in bio-composites; these fibres have a Greenhouse gas (GHG) footprint of about 60,000 times less than virgin carbon fibres. The synthesis of polymers from renewable resources is gaining importance as a solution to the critical issues of depleting crude...

Current large-scale additive manufacturing extruders use short reinforcing fibre-filled thermoplastic pellets, which marginally improve the mechanical performance but are too short to exploit the strength of the fibres fully. Long fibre pellets have much higher potential strength, and the development of higher strength materials could create...

We explain the design and analysis of a novel voxel design with the goal of reducing assembly time and complexity of the robot-material system. Recent advances in robot-material systems, on the other hand, have focused on mechanical properties, design, and production methods. Making it possible to create cellular structures in harsh and remote...

Traditional manufacturing techniques for hydrogen pressure vessels have inherent constraints in the possible geometrical and structural optimisation. Using 5-axis Additive Manufacturing (AM) allows for a far greater shaping freedom. This thesis will provide a new manufacturing method for pressure vessels with 5-axis AM. Using the highly...

Bacterial cellulose combines the high specific mechanical properties of cellulose, with the use of microbes as micron-sized factories, which are leveraged to metabolise a highly pure and crystalline intertwined network form of cellulose. In spite of its advantageous properties, the lack of shaping freedom in current BC manufacturing techniques...

Over the past decades, fibre-reinforced composite structures have been increasingly adopted into mainstream manufacturing over conventional metals owing to their higher performance attributes, such as superior strength-to-weight ratios. Composite structures offer the unique advantage of tailoring reinforcements in correspondence with design load...

Morphogenesis of living organisms could be used as inspiration to digitally augment the reinforcement of structures. The design space in terms of fiber orientation was enlarged to facilitate more complex patches with improved performance that can be 3D printed using a ghost ply optimisation. Simulations performed on optimized open-hole tensile...

Additive Manufacturing (AM) has made it possible to manufacture parts whose shape complexity was unfeasible with other traditional methods by depositing material layer-wise. However, this planar layer-wise deposition strategy can be restrictive for the part's properties. However, the anisotropic behaviour can also be embraced and used as an...
