Studying the effect of different additives on the thermal conductivity and mechanical characteristics of epoxy-based composite materials

Abstract EN

The current paper deals with investigating the effect of two different fillers on the thermal and mechanical characteristics of epoxy-based composite.

The filler used throughout the study are: charcoal and Pyrex, both of them are different in nature and have not been investigated thoroughly or even compared fairly in terms of their effect on polymer matrix.

Further, they can be considered as a cheap filler, charcoal can be obtained from a simple pyrolysis process of plants (charcoal) and Pyrex waste can be collected easily.

Both types are added to the selected matrix with volume percent ranged from 10 to 60 with increments of 10.

To ensure a fair comparison, the particle size is fixed (is about 1.7 micrometer).

The results showed that the epoxy thermal conductivity has enhanced by about two orders of magnitudes over the studied range of filler.

In terms of mechanical properties, the charcoal improves the tensile strength about 84% at 60% volume fraction while the Pyrex effect is about 40% at the same filler level.

On the contrast, the results of compressive strength do not show an appreciable improvement overall.

It decreases by about 12% at 60% volume fraction of charcoal while increases about the same percent with Pyrex at the same filler level.
