Data supporting micromechanical models for the estimation of Young's modulus and coefficient of thermal expansion of titanate nanotube/Y2W3O12/HDPE ternary composites

Abstract

This article presents several micromechanical models to predict the Young's modulus and the coefficient of thermal expansion of titanate nanotube/Y 2 W 3 O 12 /HDPE composites. The equations and assumptions of the selected micromechanical models are described in detail for this ternary system. Data of the elastic constants, coefficient of thermal expansion of composite components and other associated parameters, obtained either by literature survey or processing of literature information, are compiled in this work. For further interpretation of the data presented in this article, please see our research article entitled “The effect of titanate nanotube/Y 2 W 3 O 12 hybrid fillers on mechanical and thermal properties of HDPE-based composites” (Pontón et al., 2019).

Negative and Near-Zero Thermal Expansion in A2M3O12 and Related Ceramic Families: A Review

“…In the past decade, the development of composites exhibiting controlled and reduced thermal expansion has triggered considerable research in several different areas (Lind, 2012;Sharma et al, 2012;Pontón et al, 2019a;Pontón et al, 2019b). A number of different ceramic fillers, including A 2 M 3 O 12 and related families, have been used with the goal of counteracting the (usual) positive thermal expansion of ceramic, metal and polymer matrices.…”

“…Note that A 2 M 3 O 12 and related materials can be combined with other fillers, such as TTNT and CIPs to form hybrid fillers (see Table 3), improving the mechanical and microwave absorbing properties, respectively, while causing a substantial decrease in the CTE of the composites (Zhou et al, 2015;Pontón et al, 2019b). A detailed description of the micromechanical models that can be applied to predict the CTE of these ternary PMCs has been published (Pontón et al, 2019a).…”
