Abstract

In this paper, the effective coefficient of thermal expansion (CTE) of novel interpenetrating phase composites (IPCs) based on the mathematically-known triply periodic minimal surfaces (TPMS) is investigated. In these IPCs, different TPMS architectures are used as reinforcing solid sheets to produce composites with lower effective CTE. Several three-dimensional unit cells are generated and studied using the finite element method to estimate the effective CTE for various TPMS-based IPC architectures. The obtained results are compared with some analytical models and conventional composites. The proposed IPCs have shown promising results compared with the conventional composites.
