Structure and properties of PP/SBS/glass fiber hybrid composites. Part II:Property measurement

The mechanical properties viz. impact and tensile modulus of hybrid composi tes of PP/SBS/glass in the composition range 0-40 wt% of glass fibers (GF) were studied. Both impact and tensile modulus increased with respect to gla ss content at a certain composition of the blend, Synergistic effects were seen in the value of elongation and toughness at a certain composition of t he glass content. The above findings could be associated with the high aspe ct ratio and nucleation ability of GF together with good interfacial adhesi on between the GF and SBS, rather than the PP matrix. These have been suppo rted by the investigations on structures and morphologies of the hybrid com posites.
