Temperature dependence on thermal and strength properties of aluminum based high thermal conductive composites containing VGCF-CNT fillers

Aluminum (Al) based composites containing vapor-growth carbon fibers (VGCF) and carbon nanotubes (CNT) has been developed by authors for a decade using spark plasma sintering (SPS). It has been clarified that the thermal conductivity of the composite is three times higher than that of a normal Al ma...
