Modification of Epoxy Resin with Silica Nanoparticles and Process Engineering of Composites Based on Them

Studying a heterogeneous material based on epoxy oligomer filled with silica by microindentation

“…This fact indicates a uniform distribution of particles within the polymer matrix subjected to ultrasonic treatment, at the microlevel. Thus, ultrasonic processing provides for a uniform distribution of the modifying particles in the matrix at the microlevel and, as a consequence, a uniform distribution of the hardness values and the reduced modulus in terms of material, and this confirms the previously obtained investigation results [2].…”

“…A sample of Primer 204 epoxy resin with the addition of Tarkosil T-20 silica with 2 %, 4 %, 6 %, 8 % and 20 % volume content was studied [2]. The samples were prepared at the Khristianovich Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences and the N.N.…”

Investigation of local mechanical properties of materials in welded joints of the VT1-0 titanium alloy and the 12Cr18Ni10Ti austenitic corrosion resistant steel with an intermediate copper insert with the use of a nanomechanical testing system

“…Besides, it is always necessary to remember about the presence of border zones, which are also different in mechanical properties and may be involved in the problem on evaluating the strength and serviceability of the welded joint, as one of the constituents with its own mechanical properties. The obtained experimental data on indentation will later on be used for constructing flow stress curves with the application of the technique found in [7]; these flow stress curves, in their turn, will be used to simulate the stress-strain state of a welded joint under loading, and they will offer practical recommendations for further work with this type of welded joints.…”

“…In this case, the kinetic indentation method may be applied quite well. In this study, it was decided to resort to the modern nanomechanical complex NanoTriboindentor TI 950 [5][6][7]. The elastic modulus and hardness were determined by the Oliver-Pharr method [8] in accordance with the international ISO 14577 standard.…”
