EFFECTS OF EPOXY RESIN ON THE DAMPING PROPERTIES OF A PVA-BASED MATERIAL
Some studies have been conducted to obtain an effective vibration-absorbing mastic based on polyvinyl acetate. Based on the planning matrix, an optimal composition of the working matrix is identified. The working matrix is modified with epoxy resins. It is found that introduction of UP-563 epoxy resin in an amount of 10 % of the working matrix mass leads to an increase of the loss coefficient by 35 %.
