The investigation of disperse filler wollastonite influence on the viscoelastic properties of GRP

The viscoelastic properties of structural glass-reinforced plastics based on the resins Epikote-828 and filled with the natural mineral - wollastonite, were studied by dynamic mechanical analysis (DMA). The investigation was performed at the interval of temperatures ranging from 20 to 160 °C. Studying of the basic relaxation processes revealed the effectiveness of wollastonite application as a dispersed filler for creation engineering glass-fiber materials with in advance set physical mechanical properties.
