Potential of porous pyrolytic carbon for producing zero thermal expansion coefficient composites: A multi-scale numerical evaluation

This paper investigates the feasibility of using porous pyrolytic carbon (PyC) to produce low thermal expansion (CTE) carbon/carbon composites by using a multi-scale representative volume element (RVE) based on a finite element (FE) homogenisation strategy. The distribution of pores is characterized by mercury intrusion test and multi-peak Gaussian function. The RVEs of porous structures at micro- and macro-scale are generated using a modified...
