“…As a result, the RWPs were not able to support stresses transferred from the matrix. The slight decrease in the tensile strength with increasing WP content was observed in other studies on WF-PP composites (Zaini et al 1996;Tajvidi and Ebrahimi 2003;Yang et al 2006). Cheng et al (2009) concluded that the flexural strength of WF-PP composite decreased slightly as WP content increased.…”

“…The values of water absorption for the WPC with 60 % RWPs were approximately 2.7 times and 1.8 times greater than those for the WPC with 20 % RWPs, for the water absorption after 24 h and 28 days, respectively. The water absorption in the WPC is due to the wood component because the PP component does not absorb any moisture as a hydrophobic material (Tajvidi and Ebrahimi 2003;Yang et al 2006;Ashori and Nourbakhsh 2008). The hydroxyl groups inside the cellulose and hemicelluloses attract the water molecules and form hydrogen bonding.…”

Properties of wood–plastic composites made of milled particleboard and polypropylene

et al. 2014

Particles derived from milling three-layer particleboards, with sizes from 0.5 to 3 mm, were used for making composites with polypropylene by an injection moulding method. Maleated polypropylene was used as a coupling agent. The objective of this study was to evaluate the mechanical and physical properties of the composites made from particleboard and polypropylene with respect to the content of particles derived from particleboard and coupling agent addition. Properties of the composites did not differ significantly from those of composites with virgin industrial wood particles used for manufacturing particleboards. Moreover, these properties were comparable with the properties of typical wood-plastic composites with wood flour. Particles derived from milling particleboards have proved to be an effective alternative wood component of wood-plastic composites.

“…Unmodified OPMF acted as filler in the resin matrix, which actually weakened the composite because of the poor interfacial adhesion, obstructed the stress propagation, and caused the tensile strength to decrease as the filler loading increased (Yang et al 2006). On the other hand, the incorporation of more hydrophobic silane-treated OPMF led to better tensile strength because the modified fibers were more hydrophobic than the unmodified OPMF, as shown in the FTIR spectra of our previous study (Eng et al 2014b).…”

Effects of modifying oil palm mesocarp fibers (OPMF) by methacrylate silane on polylactic acid (PLA)/ polycaprolactone (PCL)/clay/OPMF hybrid composites were investigated. The composites were prepared by a melt blending technique and characterized by dynamic mechanical analysis (DMA) and scanning electron microscopy (SEM). The silane-treated OPMF hybrid composites showed better tensile strength, tensile modulus, and elongation at break than unmodified OPMF hybrid composites. DMA analysis showed an increase in storage modulus when silane-treated OPMF was added to a hybrid composite. The loss modulus curve showed that the incorporation of silane-treated OPMF into a hybrid composite shifted the two glass transition temperatures (Tg) of composites closer to each other. The low tan δ peak indicated good fiber/matrix adhesion for the silane-treated OPMF hybrid composites. SEM micrographs revealed that silane-treated OPMF hybrid composites showed better fiber/matrix adhesion than unmodified OPMF hybrid composites because of absence of gap between silane-treated OPMF and the matrix in the composite.

“…This is due to the hydrophilic PKS that contains hydroxyl group, which bonds with water molecules through hydrogen bonding [32] . As more filler is added to the PP matrix, more hydrogen bonding formed between hydroxyl group and water molecules, thus increasing the water absorption of the composites [33] .…”

Effects of polypropylene methyl polyhedral oligomeric silsesquioxanes and polypropylene-grafted maleic anhydride compatibilizers on the properties of palm kernel shell reinforced polypropylene biocomposites

et al. 2016

SbstractThe effects of the polypropylene-grafted maleic anhydride (PP-g-MAH) and polypropylene methyl polyhedral oligomeric silsesquioxane (PP-POSS) compatibilizers on the mechanical, thermal and physical properties of palm kernel shell (PKS) reinforced polypropylene (PP) were investigated. The production of PP/PKS biocomposites was performed by melt mixing using Brabender Internal Mixer. Mechanical test results showed that the biocomposites with PP-g-MAH have better tensile strength compared to biocomposites with or without PP-POSS. The results also showed an increase in the tensile strength and elongation at break when compatibilizers were added. Polypropylene-grafted maleic anhydride improved the Young's modulus of the biocomposites, but PP-POSS reduced it. Moreoever, adding compatibilizers in biocomposites reduced the water absorption of the biocomposites. The compatibilizers improved the nucleating ability of filler in the composites. The PP-g-MAH compatibilizer provided better performance in improving nucleating ability to biocomposites compared to PP-POSS.
