This study examined the temperature that develops in the tool cutting process during rough turning on an experimental basis by using a model for the polycrystalline cubic boron nitride (PCBN) tool. The cutting tool temperature has significant effect on the future performance of a tool and the quality of its machined component and is therefore important to explore. The thermal conductivity of the PCBN tools was determined at room temperature ...
In the present study, boron nitride/dicyclopentadiene bisphenol cyanate ester/bisphenol A dicyanate ester (BN/DCPDCE/BADCy) composites were investigated for the effects of filler mass on thermal and mechanical properties. Thermal conductivity was measured using an instrument by transient plane source method. With the addition of BN fillers for BN/DCPDCE/BADCy composites, the BN-BN connections of inner composites increased and formed more thermally conductive channels, resulting in improved ...
In efforts to develop polymers possessing high thermal conductivity, ultra-high-molecular-weight polyethylene (UHMWPE)/boron nitride particles (BNp), UHMWPE/BN sheets (BNs), and UHMWPE/(BN+MWCNT) hybrid filler composites were analyzed in this study. Thermal conductivity was measured using the transient plane source (TPS) method. Results show that conductive pathways were formed in the composites, increasing both the connection between particles and the thermal conductivity. BNp-filled UHMWPE composites had an overall higher ...
This study aimed at developing polymer-based dielectric materials with high charge-discharge efficiency and large energy density at high temperatures. A polymer nanocomposite was formed using c-BCB polymer matrix with two-dimensional hexagonal boron nitride nanosheets (BNNS). Using a transient technique, thermal conductivity was measured with a Thermal Analyzer. The incorporation of BNNS into PMMA was found to increase thermal conductivity and enhance properties of the nanocomposites....
Thermal conductivity of neat-epoxy resin is one of the lowest among all known solid materials. A common method of increasing thermal conductivity is through the addition of filler particles with high thermal conductivity. In this study, epoxy resin composites were studied to assess the possibility of increasing thermal conductivity for effective heat dissipation. A typical industrial liquid epoxy was used with commercial boron nitride powders PT100 and PTX25 as fillers. ...
