Compression Strength and Fracture Properties of Model Particulate Food Composites in Relation to Their Microstructure and Particle‐matrix Interaction

“…1987) in gelatin, a relatively hard gel. It would be expected that the properties of the filler-matrix interface, and hence particle size, should be important (Manson 1985), but in both the above studies the effect of particle size was found to be small. Gels containing oil droplets, soft particles in a soft matrix, would also be expected to obey rheological or composite theories, but to date only the conditions required for satisfactory preparation of composites, mainly very small oil droplet size, have been established (Miura and Yamauchi 1984;Jost et ul.…”

Characteristics of Gel Time and Dielectric Strength of Epoxy Composite According to the Mixing Ratio of Micro-Fillers

“…In addition, when the temperature inside the epoxy increases due to the exothermic reaction generated in the curing process of the epoxy resin, the reaction rate that affects the cross-linking mechanism and internal mechanical stress is changed, which causes internal cavities and surface deformation [9]. Therefore, in order to improve the insufficient mechanical and thermal properties of epoxy resin, research on epoxy composites is being conducted to improve tensile strength, compression, coefficient of thermal expansion, glass transition temperature, etc., by polymerizing, dispersing rubber or adding inorganic micro-fillers [10][11][12][13][14][15].…”

Fracture mechanics of dissimilar materials bonded through an orthotropic interfacial zone

“…From the viewpoint of applications generally the optimal design of interfacial regions involves tradeoffs between strength and toughness. For example, it is known that the untreated carbon has very poor adhesion to epoxy and good adhesion can be accomplished by treating its surface and by using proper coupling agents (e.g., variety of silanes) [4].…”

“…In other bonded materials the interfacial regions having their own structure and thickness may develop as a result of surface preparations and coupling agents used in processing. For example, in many of the polymer matrix composites very near the interface crystallization of the polymer or copolymerization of the matrix and the coupling agent seems to produce a highly oriented region with a columnar or lamellar structure which may generally be modeled as a thin orthotropic layer (e.g.. PEEK-Carbon composites) [4]. [9].…”
