Structure and Properties of PP/SBS/Glass Fiber Hybrid Composites. Part II: Property Measurement

摘要

The mechanical properties viz. impact and tensile modulus of hybrid comosites of PP/SBS/glss in the compositoin range 0-40 wt% of glass fibers (GF) were studied. Both impact and tensile modulus increased with respect to glass content at a certain composition of the blend. Synergistic effects were seen in the value of elongation and toughness at a certain composition of the glass content. The above findings could be associated with the high aspect ratio and nucleation ability of GF together with good interfacial adhesion between the GF and SBS, rather than the PP matrix. These have been supported by the investigations on structures and morphologies of the hybrid composites.
