“…13 Moreover, addition of filler particles in mould material increases the effective modulus of elasticity of mould materials. 14 , - 16 In the present work, an extensive experimentation is carried out to find the effect on equivalent thermal and mechanical properties of SR composites by reinforcing various metallic and non-metallic filler particles independently with different loading conditions. In this work, the experimental study on ETC of SR composite is carried out using the filler materials namely grey iron, aluminium, copper, magnesium, titanium, zinc, graphite, silicon, and glass, whereas only Al and graphite are considered in the study on equivalent modulus of elasticity of SR composites.…”

The main disadvantage in soft tooling process using conventional flexible reactive polymeric mould materials, namely silicone rubber, is the longer solidification time of (wax/plastic) patterns that yields to reduce the rapidity of the process to a great extent, which is not desirable in the present competitive market. The approach of particle reinforcement with mould materials is introduced here to reduce the cooling time of soft tooling process and the resulting cooling time is experimentally investigated in considering a case of manufacturing of a typical wax pattern with aluminium particlereinforced silicone rubber mould material. It is observed that cooling time is significantly condensed, particularly with higher loading condition of aluminium filler. This is due to the increase of equivalent thermal conductivity of mould material. However, it is also noticed that at the same time, the stiffness of mould becomes high due to the increase of equivalent modulus of elasticity of mould material. Therefore, in order to effectively utilize the particle-reinforced silicone rubber for preparing mould, it is important to have a perceptive on the equivalent thermal conductivity and modulus of elasticity of composite mould materials with different filler loadings. Based on this realization, an extensive study is carried out to find the effect on equivalent thermal properties and modulus of elasticity of silicone rubber composite mould materials with the reinforcement of various metallic and non-metallic filler particles independently through rigorous experimentation and correlation of experimental findings with the models cited in literatures.

“…Leidner and Woodhams (1974) examined the dependence of the fracture strength of a particulate composite upon the bond strength by approximating the inclusion by a series of cylinders, to enable direct application of the established fibre reinforcement theories. Papanicolaou and Bakos (1992) divided each inclusion into an infinite number of coaxial cylinders, and the stress developed in each section is calculated by considering the degree of adhesion between the inclusion and the matrix.…”

An analytical model is developed to characterise the strength of syntactic foams (hollow spherical inclusions typically embedded in a polymeric matrix) by analysing the state of stress around the inclusions with imperfect adhesion with the matrix. Using a three-phase model with imperfect interface between the inclusion and the matrix, the state of stress around the particle is determined. Employing the concept of stress concentration factor, a predictive model for computing the failure strength of syntactic foam is presented by considering the increase in stress concentration with volume fraction and the degree of interface bonding degradation. The theoretical predictions are compared with the test data available in the literature for hollow glass beads dispersed in polymeric matrices. The predicted strength values correlate well with the test data.

“…The present work is an effort to study the static bending behavior of aluminum‐filled epoxy particulate composites with and without notches and also to correlate experimental results with respective theoretical predictions based on micromechanics 1–12. Several semi‐empirical models/expressions developed by Papanicolaou et al and by others were used and their predictions were also compared with respective experimental results 13–26…”

“…First, for the evaluation of the maximum strength the particle sectioning model (PSM) was applied 13. According to this model, each particle is divided into an infinite number of coaxial cylinders and by applying Cox's theory the mean stress developed in each section of the particle may be calculated.…”

The aim of the present investigation is to study both the influence of particle weight fraction (0-50%) and the effect of the notch length on the static mechanical properties of aluminum particle epoxy composites. Experimental results in both cases were compared with three different theoretical models, previously developed by the first author and presented in a series of publications. First, for the evaluation of the maximum strength the particle sectioning model (PSM) was applied. Next, for the evaluation of the elastic modulus as a function of aluminum powder weight fraction, the interphase model (IM) was applied. Finally, in the case of notches' length influence, the residual property model, (RPM), was applied. This model can be applied for the description of the residual behavior of materials after any type of damage. In all cases, predicted values showed a satisfactory agreement with experimental findings. PREDICTIVE MODELS Predictive models for the elastic modulusThe mechanical properties of particulate-filled composites are affected by a great number of geometrical, topological, mechanical, etc. parameters.
