Athermal Failure of Epoxy Composites

The Composite Models Application for Elastic Modulus of Poly(Ethylene Terephthalate)/Poly(Butylene Terephthalate) Blends Description

“…By its physical essence interfacial adhesion between PET and PBT represents the formation of autohesional bonding, shear strength of which  c can be determined as follows [15]: 5 3 83 6 28 10…”

“…Nevertheless, the blends PET/PBT can be considered as polymer/ polymeric composites [11], particularly at the condition, that one polymeric phase is dispersed in another as disperse particles with the size of 0.2-1.5 mcm [10]. With appreciation of the stated above considerations the purpose of the present work is the treatment of blends PET/ PBT as polymer/polymeric composites within the frameworks of micromechanical [1] and per colation [5] models for qu antitative description of the extreme dependence of their elastic modulus on composition.…”

Fractial parameterization of the structure of filled polymers

“…Thus, there are strong grounds to expect a similar size distribution for particles of a disperse filler in filled polymers as well, particularly when aggregation of particles is possible. There is another reason for the assumption of a fractal distribution of filler particles, which, as is known [14], can form a percolation cluster when their content reaches a certain magnitude. Near the threshold of percolation, the cluster, in turn, has a fractal structure [13].…”
