“…Irrespective of the filler type, incorporation of the filler resulted in an abrupt drop in elongation at break compared to the elongation at break of PP (Table 2). A similar behavior has been reported by Qiu et al [16] It is also reported that the Young's modulus increases while elongation at break decreases with increasing filler loading. [17] A similar trend can be seen here for these composites studied in this work.…”

Poly(propylene) (PP) composites were prepared by using eggshell (ES) as filler and their mechanical properties were compared with those using talc (TA) and calcium carbonate (CC) of different grain sizes (X50). A decrease in impact strength and deformation at break with increase in filler content was observed. The PP composite with ES (X50 = 8.4 µm) was stiffer than those with CC (X50 = 0.7 µm). The hybrid composite PP‐ES‐TA showed a similar stiffness as the PP‐TA composites due to the similar morphology of TA (X50 = 0.5 µm) and ES, when TA was replaced up to 75 wt.‐% by ES. SEM study revealed evidence of improved interfacial bonding between PP and ES in theirs composites.

“…The addition of fillers into PP matrix has been an accepted route to achieve enhancement in material properties or/and cost saving possibilities. Talc, a plate-like layered structure magnesium silicate mineral, in which the octahedral brucite layer is sandwiched between two tetrahedral silica sheets, has proved to be particularly efficient filler on the mechanical properties and macromolecular orientation of compounds [2][3][4][5][6] and consequently an increase of the performance of reinforced polymeric matrix. At low concentrations (less than 3 weight%), talc acts as a nucleating agent, reducing spherulite size and shortening processing time [7].…”

Talc represents one of the most useful mineral fillers which are compatible with the polypropylene (PP). It is characterized with its lamellar structure. The introduction of 30% by weight of talc, three types differing with the particle size d 50 and the composition, has not only a positive influence on stiffness and crystallinity but also it decreases the impact strength and tenacity. The abrasive wear behavior depends mainly on the particle size of talc. Microscopic observations revealed that the talc layers are aligned along the injection flow direction, and uniformly dispersed in the PP matrix.

“…Polymers are traditionally reinforced with synthetic or natural inorganic fillers in order to improve their properties and reduce their costs [2]. Commonly used fillers are clay, talc, mica [3,4] and fibrouslike glass, carbon fibers, aramid, and jute fillers [5,6]. In order to improve or modify certain thermomechanical properties of polymers for specific applications, composites based on short fibers reinforced polymers find increasing applications in engineering and consumer products [7].…”

Hybrid composites of polypropylene (PP)/sodium montmorillonite (Na-MMT)/short polyamide fibers (PAfs) were prepared by reactive melt mixing in a Brabender plastograph. To enhance filler interactions within polypropylene, a functionalizing agent (FA) and a coupling agent were added to the Na-MMT and PAfs, respectively. An organic peroxide/sulfur mixture and tetramethylthiuram disulfide as an activator for sulfur were used to functionalize Na-MMT; on the other hand, the PAfs surface was treated using stearic acid. The aim of this study is to investigate how the morphology and the structural properties of 3, 5, and 7 wt% recycled functionalized sodium montmorillonite nanocomposites (f-Na-MMT) are affected by the presence of 5 wt% treated short polyamide fibers (t-PAfs). According to the obtained results, 5 wt% recycled f-Na-MMT/5 wt% t-PAfs/PP hybrid composite showed Na-MMT layers exfoliation. The nucleating effect of f-Na-MMT and t-PAfs was indicated by the differential scanning calorimetry (DSC) measurements. Morphological analysis of the hybrid composites was performed using scanning electron microscope (SEM) and optical polarized microscopy (POM), showing a good dispersion of the fibers with an interesting interfacial adhesion between the PP and t-PAfs phases. Hybrid composites of PP/f-Na-MMT/t-PAfs are considered for automotive industry.
