| Summary: | 碩士 === 逢甲大學 === 紡織工程學系 === 89 === The aim of this study is to investigate the effect of fiber volume content, woven structure, bulk density, and open void content on thermal conductivity of woven carbon/ carbon composites. Plain, twill, satin, and spiral woven fabrics were used to fabricate the composite precursor of the carbon/carbon composites. The composite precursors were treated by different temperature and cycle times of densification. The results show that the fiber volume content and thermal conductivity of plain, twill and satin woven C/C composite laminates were sort in order of plain > twill > satin under the same thickness and number of stacking layers. Thermal conductivity of these three composites is increased with heat treatment temperature and cycle times of densification. However, the thermal conductivity of these composites was sort in order of satin > twill > plain under the same fiber volume content. The thermal conductivity of the spiral woven C/C composite is higher than the other C/C composites due to the fiber formed by compaction and radial arrangement in the spiral woven fabric.
