...It is known that if polymer matrix-filler adhesion is poor, yielding is always observed, similarly as in the pure matrix [27]....

...One of the most prominent models is Nielsen and Lewis model [27,32,33], which can be generally applied for different properties of composites such as Young’s modulus and also thermal and electrical conductivity of composites [34,35]....
[...]
...It has been established in the scientific literature that the improvement of tensile modulus depends not only on the Young’s modulus of components but also is influenced by the good dispersion of particles and good interfacial adhesion between filler and the matrix [27–29]....
[...]
...The most well known model, describing the decrease in elongation at the break with an increase in filler volume fraction, is the Nielsen model [27]....

...Physical arguments for the observed behaviour are well assessed but theoretical models are scanty or just semi-empirical [36, 49]....
[...]
...According to Nielsen [36] experimental data are often erroneously too low (lower than theoretically predicted) because of two other possible reasons: a “skin effect” (i....

...With particles order-of-magnitude softer than the embedding matrix the different theoretical (or semi-empirical) equations almost collapse one onto the other [36-38] but their predictive capacity remains uncertain....
[...]
...Mostly the theoretical treatments refer to binary composites and assume perfect adhesion between filler particle and polymer matrix at their interface, which, as noted by Nielsen [36], often results in overestimating the modulus of the composites containing particles harder than the matrix....
