This paper presents experimental results made  to obtain a composite material with glass matrix disperse reinforced with silicon carbide powder.

The glass matrix waste (E-type glass fibres) was grounded, with a specific surface area between 3500 - 4200 cm²/g, and the reinforcing material was the powder of SiC (F120 and F600) in a ratio of 10%, 20%, and 30%.

We determined the following physical and mechanical properties: density, porosity, thermal expansion. In order to characterize in terms of composition and microstructural we performed X-ray diffraction analysis and scanning electron microscopy measurements which showed the influence of the SiC powder particle size on the properties of the composite.
