Summary

Properties of continuous glass fibres produced on the base of tv-tube glass waste on laboratory and industrial scales are investigated. The thermal-viscous constants tv-glass are relatively small and mechanical properties of fibres are slightly worth compared with E-glass fibres but chemical resistance especially in acid is high due to the heal effect of acid treatment as well as stability of the silica lattice. High amount of lead oxide in the fibres based on the mixture of socket and neck parts of tv-tube waste allows to reach an attenuation of radiation of about 40 % in the neutron field and about 20% in the photon field for test specimen produced using such fibre as reinforced element of composites with polymer matrix. Development of composites is of course only possible via proper combinations of such fibre and corresponded matrix.
