METHOD OF IMPROVING PHYSICAL AND MECHANICAL PARAMETERS OF FIBRE-GLASS Russian patent published in 2016 - IPC C08J5/08 C08J5/24 C03C25/62 C08K7/14

Abstract RU 2592578 C1

FIELD: technological processes.

SUBSTANCE: invention relates to composite materials. Method involves preliminary processing of glass-fibre filler containing sizing agent-"paraffin emulsion", low-temperature plasma of glow discharge of alternating current with frequency 50 Hz using air as working gas at low pressure, subsequent impregnation with polymer binder. Treatment of glass-fibre filler is carried out in area of negative luminescence of abnormal glow discharge of low-temperature plasma. Continuous change of working gas with maintenance of constant total pressure is carried out. Method includes impregnation with moisture-resistant polymer binding materials, having low indices of moisture absorption.

EFFECT: improved interlayer adhesion, moisture resistance.
