The Formula for Correlation between Porous Phase and Macro-mechanical Characteristics of the Material | Chapter 9 | Current Topics and Emerging Issues in Materials Sciences Vol. 1

 Determination of the equating of characteristics of combined body with content, height, distribution in mold and shape factor of porous development. The goal of the following paper search out determine formula for equivalence between traits of ceramics and ceramic composite fabrics and porous stage, which is the weakest unspecified material. This will allow theorists and practicists to right choose and improve electronics and technical processes. According to the study and reasoning of micro- and macrostructural, micro-and macromechanical of potteries and ceramic composite fabrics, parameters of the formula was driven. Formula contains macromechanical features. When detail is completely decomposed: mechanism on bending by three or four-point load, mechanism on shrinking, breaking, impact resistance. Morphologic traits: Porous phase content in the origin and its distribution, capacity, shape factor of pores. Correlation of likely factors with possible choice structural traits, such as: crystal and cup phases. Novel perseverance of pore distribution factor is likely. Created formula has composite nature and using it admits researchers and practicists to right plan and precisely preform all the positions of the concerning details production.

Determination of Stress-strain State of the Interfacial Layer in a Whiskerized Fiber Composite with Longitudinal Shear | Chapter 7 | Recent Trends in Chemical and Material Sciences Vol. 3

 The effective properties of composite materials reinforced by whiskerized fibres are determined using a three-phase approach proposed in this study. The study considers a modified composite made up of two phases: a fibre and a whiskerized layer that acts as a binder. Calculations of the stress-strain state in each phase and calculations of effective properties are performed for a modified composite loaded with longitudinal shear. The strength of the composite is assumed to be controlled by the binder in the case of pure shear along the fibre; therefore, the deformed state in each of the phases of the modified composite is investigated, and a comparison with the deformed state in each of the phases of a similar classical composite is performed. A comparison of the computed values of the effective longitudinal shear modulus and effective loss modulus is also performed. The effects of rigid CNTs and less rigid ZnO nanotubes on two types of modified composites are explored.
