After preball milling, the inplane TC of the composite film is reduced. It decreases from to W/mK for BN/PEI composite film at 30 wt% content; however, the throughplane TC of composites is improved, and the breakdown strength and tensile strength of the composite film reach the maximum of kV/mm and MPa at 5 wt% content ...

Reinforcement types have an important role in ballmilling behavior of the composite powders. The morphology of the three composites powders (Fig. 3) shows that the NCHEA particles are almost fully wrapped in the Al matrix after ball milling, which contributes to a uniform distribution of the NCHEA p in the composite powders. SiC particles ...
