A comparison study of different ceramic filler on mechanical and thermal properties of glass, carbon, kevlar polyester composites

الملخص EN

Fillers play a major role in determination of the properties and behavior of particles on (glass, carbon, and Kevlar fiber) reinforced polyester composites.

These particles are fabricated using both alumina (Al2O3) and silicon carbide (SiC) particles as filler materials for such systems.

The effect of these two different ceramic polyester composites are investigated at different additive ratios as (0.2, 0.4, 0.6, 0.8, 1.0) volume fraction.

Comparative analysis shows that the bending distortion, Hardness, and Impact resistance are affected by the type and content of filler particles, where both impact and Hardness is increased with increasing volume fraction specially in case of (0.5) volume fraction for both filler particles and decreased for bending distortion specially in case of glass fiber/ polyester at (0.5) volume fraction for both filler particles.

Also high electrical properties for all filler/ fiber/ polyester composites.

It is shown that silicon carbide (SiC), have better filler characteristics compared to those of alumina (Al2O3) .Hopefully, these results provide a cost effective solution to composite applications.
