Abstract

This work investigates whether shape stabilisation and thermal performance in phase change material (PCM) composites can be independently optimised to produce lightweight, cost-effective thermal energy storage materials. A hybrid composite comprising polyethylene glycol (PEG-1000) as the latent heat storage medium, carboxymethylated cellulose (CMC) to address leakage, and aluminium open-cell foams for thermal conductivity and mechanical reinforcement was developed. This approach aims to retain the benefits of metal foams while minimising the proportion of material not contributing to heat storage. Thermal conductivity increased with pore density (PPI), reaching ~2.2 W·m⁻¹·K⁻¹, while specific heat was mainly governed by relative density (RD). A key performance index identified 20 PPI 4-6% RD as the optimal architecture.
