Adhesion factor to cube in cube models and its effect on calculated moduli of particulate composites the cube in cube approach was used by paul and ishai-cohen to model and derive formulas for filler content dependent young`s moduli of particle filled composites assuming perfect filler an elementary volume approach which transforms spherical inclusions to cubic inclusions

HIGHLIGHTS

SUMMARY

The cube in cube models of Paul (upper bound) and Ishai-Cohen (lower bound) determine the moduli of particle filled composites assuming perfect filler-matrix adhesion. To take into account reduced adhesion between filler particles and matrix polymer their models were recalculated using an EV approach, and extended by an adhesion factor kadh that scales the edge length of the cubic inclusion. The modified model allows for design engineers to calculate realistic modulus of any particulate composite using only matrix and filler moduli, filler content and adhesion factor without √ performing tests. The EV approach . . .
