Abstract

This study investigated the effects of carbon fibers and graphite flakes on the composite materials' heat dissipation properties and mechanical strength with various hybrid ratios in the matrix. Carbon fibers and graphite flakes with high thermal conductivity showed efficiency in heat dissipation performance, and mechanical strength was reinforced by carbon fiber. However, the heat dissipation performance and mechanical strength were greatly changed according to the mixing ratio. The optimal filler mixing ratio was derived for inducing the enhanced physical properties of the composites reinforced by hybrid fillers with different shapes.

摘要

本研究调查了碳纤维和石墨片对基体中不同混合比例复合材料散热性能和机械强度的影响。具有高导热性的碳纤维和石墨片在散热性能方面表现出有效性，并且碳纤维增强了机械强度。然而，散热性能和机械强度会根据混合比例而发生很大变化。推导了最佳填料混合比例，以诱导由不同形状的混合填料增强的复合材料的物理性能得到提升。
