Effect of SiC particles and water absorption on thermal conductivity of epoxy reinforcement by (bi-directional)‎ glass fiber

Abstract EN

In this study the thermal conductivity of the epoxy composites were characterized as function of volume fraction, particle size of fillers and the time of immersion (30, 60, 90) days in water.

Composites plates were prepared by incorporating (bi-directional) (0º-90º) glass fiber and silicon carbide (SiC) particles of (0.1, 0.5, 1) mm as particle size at (10 %,20 %,30 %,40 %) percent volume in epoxy matrix.

The composites shows slightly increase of the thermal conductivity with increasing volume fraction, particle size and increase with increasing the days of immersion in water.

The maximum thermal conductivity (0.51W / m.K) was obtained before the immersion in water at 90 days for epoxy reinforcement by bi-directional glass fiber and SiC particles with volume fraction 40 % and particle size 1mm.
