High-strength granulated glass-filled compositional materials based on polyamides and polyethylene terephthalates

The effect of the glass fiber diameter on the properties of glass-filled polyamides has been examined. It has been shown that physico-mechanical properties (impact viscosity, breaking strength, relative lengthening upon breaking, etc.) increase with the decrease of the fiber diameter, and achieve characteristics of foreign materials at d &le8 μ. A new lubricant, necessary for production of the thin fiber has been developed in PO 'Stekloplastik'. A glass reinforced material based on PETF has been developed. Its mechanical, elastic, and dielectric parameters and the moisture adsorption are given in the communication.
