Carbon Fiber Reinforced

The mechanical properties of three phase nano-modified carbon fiber reinforced polymeric composites (CFRP) fabricated using Heated Vacuum Assisted Resin Transfer Molding (HVARTM) is investigated. Eight layers of carbon fiber plain weave mats were stacked in quasi isotropic layup and Epoxy 862 resin (non–modified and modified with Boron Nitride Nanoparticles (BNNPs)) was used. For mechanical properties characterization, three ASTM tests were performed. These tests included Tension Test (ASTM D3039), Compression Test (ASTM D6641) and Flexural Bending Test (ASTM D7264). The behavior of control and nano-modified composite laminates were compared. Results indicated that even small percentage of Boron Nitride Nanoparticle can significantly affect mechanical behavior of CFRP as well as progressive failure mechanisms.

The results of the research of structure and properties of a composite compact from 13 Cr – 2 Мо and BN powders depending on the concentration of boron nitride are provided. It is shown that adding boron nitride in an amount of more than 2% by weight of the charge mixture leads to the formation of extended grain boundary porosity and finely dispersed BN layers in the structure, which provides a high level of wearing properties of the material. The effect of boron nitride concentration on physical and mechanical properties is determined. It was found that the introduction of a small amount of BN (up to 2 % by weight) into the compacts leads to an increase in plasticity, bending strength, and toughness by reducing the friction forces between the metal powder particles during pressing and a more complete grain boundary diffusion process during sintering. The formation of a regulated structure-phase composition of powder compacts of 13 Cr – 2 Mо – BN when the content of boron nitride changes in them allows us to provide the specified physical and mechanical properties in a wide range. The obtained results of studies of the physical and mechanical characteristics of the developed material allow us to reasonably choose the necessary composition of the powder compact for sealing structures of the flow part of steam turbines, depending on their operating conditions.

Isoprene Rubber

The work studies vulcanization characteristics of elastomers based on isoprene rubber filled with carbon black N330 and boron nitride (BN). The influence of the boron nitride (BN) concentration on technological, dynamic, physical and mechanical properties of elastomers has been researched. The application of boron nitride for producing rubber with good properties has been considered. With a gradual increase of the inert filler BN concentration up to 35%, a decrease in the curing rate by 33% and polymer cross-link density by 26% is observed. Moreover, the start time of vulcanization increases by almost 300%, the optimal curing time by 200%.
