دراسة تأثير إضافة المايكا على خواص البولي أستر

الملخص EN

In the present research composite material was prepared from unsaturated polyester reinforced with mica as a filler material with different percent weight ratios (0.05,0.1,0.15,0.2,0.25).the effect of different percent ratios of mica particles on the electrical resistivity ,hardness, modulus of elasticity and compression strength were studied.

The results showed that the electrical conductivity, compression strength and modulus of elasticity decrease with filler content increase and the hardness increase till 10% so that the elasticity increase and the toughness of the composite material enhanced and the dielectric properties.
