are burdened by poor transverse thermal transport, which conVnues to be a significant problem for many electronics applicaVons. Much research has focused on solving this thermal issue by a5empVng to improve the through-‐thickness thermal diffusivity of carbon fiber composites. Our research has a5empted to solve this problem through the integraVon of heat spreaders into carbon fiber composites to improve the in-‐plane thermal diffusivity.
Due to poor transverse thermal conducVvity and marginal losses in mechanical properVes, we chose to focus on increasing the in-‐plane thermal diffusivity of the composite.
The results from laser flash apparatus (Netzsch LFA 427) and infrared camera tesVng showed that integraVon of heat spreader(s) significantly improves the in-‐plane thermal diffusivity of the carbon fiber composite, compared to the baseline with no heat spreader.
