Effective moduli of particle-filled composite with inhomogeneous interphase: Part I – bounds

Effect of an inhomogeneous interphase on the thermal expansion coefficient of a particulate composite

“…A similar technique was proposed by Zhong et al [26] in a two part paper. In part one of this two-part paper, Wu et al [27] constructed bounds for the elastic moduli of spherical inclusion composites based on the generalised self consistent method. In part two, Zhong et al [26] model a spherical inclusion surrounded by an inhomogeneous interphase by mapping it onto an effective homogeneous particle of identical size in order to predict the effective moduli.…”

The effect of interface debonding behaviors on the mechanical properties of microPCMs/epoxy composites

“…It is well known that the addition of particulate fillers to a polymeric resin can have a significant influence on the mechanical properties of a material. Particulate fillers can lead to fracture toughness increase by multiple phenomena including, but not limited to, crack pinning, crack bridging, microcracking, and crack deflection [13–15]. In our previous report [16], it was found that microcracks and interface separation had occurred in a repeated vigorous thermal absorbing‐releasing process for microPCMs/matrix composites.…”

Influence of filler content and interphase properties on large deformation micromechanics of particle filled acrylics

“…Basaran and Nie also proposed a modification of Ju and Chen (1994a,b) two phase model for PFCs to incorporate imperfect interfacial bonding conditions (Nie and Basaran, 2005). In order to overcome the deficiency in incorporating the true influence of imperfect interphase and interfacial debonding, several upper and lower bound models were proposed for elastic properties of PFCs (Wu et al, 2004;Zhong et al, 2004). Weng proposed a bounding method based on the work of Hashin and Shtrikman (1963) by establishment of a comparison between PFC and reference material (Weng, 1992).…”
