The experimental data are discussed concerning the polarization charge effect on physico-mechanical characteristics of polymer composite materials the components of which are in the electret state. The dependences of elastic modulus and electret charge of composites on polarization degree and filler percentage are shown. The introduction of electric polarized fillers into polymer binder leads to electret charge formation in the material and increases the elastic modulus. Thermal treatments of synthetic reinforcing fibers in stationary electric field and in corona discharge field increase the strength of reinforced plastics. The increase of strength depends on the preparation method and specimen treatment in electric field. The increase of oligomers crosslinking during electric polarization was also studied. It is shown that glass-fiber plastic specimens on the polyamide base formed between Cu and Al electrodes, keep their strength characteristics for a long time after the thermal treatment in boiling water. Such a prolonged strength preservation is conditioned by a low water absorption of electret specimens. It is proposed that polymer electrets are suitable formalizing composite materials for structural materials. |
