Multifunctionality in composites refers to their ability to carry out non-structural roles within a system and is typically achieved through hybridisation.

Constituents of multifunctional composites simultaneously and synergistically provide structural and non-structural (functional) properties to the final system. The insulating properties of the polymer matrix and low thermo-electrothermal conductivity of the fibre in the transverse direction present a barrier to various critical applications. Current approaches do not sufficiently address out-of-plane (z-direction) needs and is industrially unattractive, often requiring substantial changes to resin infusion and consolidation practices (constituent modification). A specific example is in composite battery pack enclosures, where there is a need for excellent through-thickness thermal conductivity and electromagnetic interference shielding, currently necessitating mostly metallic constructions.

The project will focus on designing bespoke through-thickness (TT) hybridising elements compatible with existing through- thickness reinforcement (TTR) techniques and planar approaches. This will provide the best combination of performance and manufacturability and will include the definition of material (or material combinations) and geometries to achieve desired thermo-electrical energy management. These configurations will be compared against and expanded by mesoscale (tow-scale) multi-physics coupled finite-element (FE) simulations to evaluate effect of local material/design on performance and to investigate and optimise the distribution of TT elements throughout the hybridised system.

Successful completion of this research will address the need for 'made-for-purpose' functional TT-elements (w.r.t topology and composition) and by the provision of predictive methods that will enable a design for functionality-weight-structural optimisation, which both are currently unavailable.

The work will make full use of facilities within the Composites and Advanced Materials Centre including thermal, and thermo-mechanical characterisation suite, pilot scale composites manufacturing equipment as well as the Mechanical Testing Lab in the School of Aerospace, Transport and Manufacturing.
