“…An alternative approach is to model the system as a parallel thermal resistor network, using the law of mixtures to estimate thermal conductivity [41], [42]. This gives good results for directions parallel and perpendicular to fibres, but cannot be used to confidently predict thermal characteristics if the heat source is not parallel or perpendicular to the fibres [26], [42]. This is because the rule of mixtures models the CFRP as a 2 dimensional, rather than a 3 dimensional system which neglects thermal interactions in the transverse (through thickness) direction [42].…”

Carbon fibre reinforced polymer (CFRP) is increasingly used for aero-structure applications due to their high strength-to-weight ratio. The integration of the on-board electrical power system (EPS) with CFRP is challenging due to the requirement to thermally and electrically isolate these systems to meet existing safety standards. By capturing the thermal characteristics of CFRP at a macro (component) scale for CFRP components, it is possible to understand, and design for, the increased integration of the EPS into CFRP aero-components. A significant challenge is to develop a macroscale characterisation of CFRP which is not only of an appropriate fidelity for compatibility with systems level models of an EPS, but can be used to represent different geometries of CFRP components. This paper presents a novel methodology for capturing a transient, macro-scale thermal characterisation of CFRP with regards to component lay-up and geometry (thickness). The methodology uses experimentally derived thermal responses of specific resin and ply orientation CFRP samples to create generalised relationship for the prediction of thermal transfer in other sample thicknesses of same material type. This methodology can be used to characterise thermal gradients across CFRP components in aircraft EPS integration applications, ultimately informing the optimised integration of the EPS with CFRP.

“…Thermal conductivity of carbon fiber was inversely deduced and it was found that deviations from the assumption of one-dimensional heat flow may lead to inaccurate estimation of fiber conductivity. Fang et al 22 utilized LFA and transient FEA to study the influence of fiber orientation angle on heat transfer behavior of unidirectional CFRP composites.…”

Laser flash analysis (LFA) is an advantageous transient method, widely used for measuring thermal diffusivity of solid materials nowadays. In this paper, the thermal conductivity of graphite film enhanced carbon fiber composite was measured by LFA and the results show an unusual size-dependent effect which was considered to be due to violation of homogeneous assumptions. To investigate the size effect, numerical analyses based on the representative volume element (RVE) models were implemented to evaluate the thermal conductivities of composites with periodic microstructures. Transient periodic boundary conditions (PBCs) were proposed and applied to the RVEs for simulating the LFA. Transient simulative results obtained by applying PBCs verify the size effect and are in better agreement with the experimental data than those obtained by applying conventional adiabatic conditions. Moreover, the classical steady-state analyses on RVEs were performed for comparison. The reason for size effect was discussed in details. The present work expands the application scope of LFA to measuring thermal conductivity of complex composite and provides a perception of discreetly selecting specimen size and modifying the general LFA technique.
