In this work, the effect thermal and electric conductivity of the AlN(aluminum nitride) ceramic coating on the pitch-based carbon fibers (PCFs) reinforced composites were compared. AlN coated-pitch-based carbon fibers (ANPFs) were prepared by electroless copper-plating to enhance interfacial bonding of AlN and PCFs reinforced epoxy matrix composites and their subsequent under nitrogen gas heat treatment in order to AlN synthesis on the copper-plated PCFs. SEM, TEM, and XRD were performed to surfaces characterize the copper-plated PCFs, the ANPFs, and composites. The thermal properties of composites were measured by thermal conductivity meter and TGA. It is found that the thermal conductivity of composite materials was synergistically enhanced by the simultaneous incorporation of well-dispersed PCFs and AlN into the matrix. |
