“…Interestingly, the same change trend in the Izod values was also found in our previous work, unlike the conventional blends, the multilayered blends with low POE content have high Izod values compared to those with high POE content [9] . Generally, the introduction of POE into PP often increases the w e values of PP/POE blends [25,26] . However, it's nearly no difference in the w e values of the neat PP (C0) and multilayered blend A1-8, moreover, an obvious drop in the w e value can be found in the multilayered blend A2-8.…”

The multilayered polypropylene (PP) and poly(ethylene-co-octene) (POE) sheets were prepared by the microlayered co-extrusion system. The essential work of fracture (EWF) and the impact tensile methods have been successfully used to evaluate the toughening behaviors of the PP/POE multilayered blends under quasi-static and dynamic uniaxial tensile stress, respectively. The experimental results indicate that the multilayered structure plays a key role in the toughening behaviors. On increasing the layer number of the multilayered blends, the specific essential work of fracture, w e , increases obviously. As for the w p , there is no obvious variation in the multilayered blends with low POE content (6.79%), however, obvious enhancement is observed with increasing the layer number of the high POE content multilayered blends (16.57%). Compared with the conventional blends, the multilayered blends with 6.79% POE content are effective to increase the value of w e . Additionally, the multilayered blends with high layer numbers present absolute advantage in improving the impact tensile values.

“…Chen and his co‐workers investigated the effects of interfacial adhesion on properties of polypropylene/wollastonite composites, and found that stronger interfacial adhesion led to higher storage modulus. Fu et al researched the effect of composition on fracture behavior of polypropylene–CaSiO 3 –polyolefin elastomer system using the essential work of fracture, with increasing CaSiO 3 content, the specific essential work of fracture increased, while the specific nonessential work of fracture decreased. Švab and his colleagues studied the mechanical properties and adhesion phenomena of isotactic polypropylene/CaSiO 3 /metallocene propylene‐ethylene (mEPR) copolymers (iPP/W/mEPR) composites, the results showed that the determined mechanical properties confirmed the assumption coming out of structural investigations that mEPR elastomers were rather efficient impact modifiers than encapsulation compatibilizers for the iPP/CaSiO 3 composites.…”

The effects of filler surface treatment and content on the impact fracture toughness and flexural properties of polypropylene (PP) composites filled with wollastonite (CaSiO 3 ) were investigated. The results showed that the introduction of the filler could toughen and reinforce the PP; the influences of the filler surface treatment on the toughness and strength were significant; the values of the Izod V-notched impact strength and the Charpy V-notched impact strength of the composites increased with increasing the filler weight fractions; the values of flexural modulus increased with increasing the filler weight fractions; the flexural strength increased when the filler weight fraction was lower than 10% and then varied slightly. This toughening effect should be attributed to the stress concentration because of strip shape of the filler and to block the development of the notched cracks in the matrix, improving the notched sensitivity to the impact fracture of the PP composites. This study should be helpful to understand the mechanisms of CaSiO 3 reinforcing and toughening PP resin. POLYM. COMPOS., 00:000-000, 2016.

The effects of the filler content and its surface treatment on the tensile and flow properties of the polypropylene (PP) composites filled with wollastonite (CaSiO 3 ) were investigated. The results showed that the introduction of the filler could reinforce the PP resin, while the influence of the filler surface treatment on the tensile and flow property was insignificant. The melt volume flow rate (MVR) of the composites decreased nonlinearly, while the Young's modulus increased nonlinearly with increasing filler weight fraction (ϕ w ); the tensile strength and tensile fracture strength increased significantly when ϕ w was < 10% and then decreased slightly with increasing ϕ w . The elongation at break decreased significantly when ϕ w was < 10% and then decreased slightly with the increase of ϕ w . Moreover, the Young's modulus was estimated using the equation published earlier, and a good agreement was shown between the predicted data and the measured data.
