“…These composites are made of the mixture of fibers, wood particles and other lignocellulosic materials, such as wheat stalks and straw, canola, rice, and melted jute with thermoplastic polymers (plastic) (Klyosov, 2006;Ismaeilimoghadam et al, 2016). Wood fiber plastic composites (WFPC) are mixtures of polymer and cellulose materials (Samariha et al, 2013;Kiaei et al, 2017a;Kiaei et al, 2017b). The addition of fibers and natural fillers to reduce costs in the plastic industry and sometimes increase the production have drawn attention after relatively increased plastic costs in previous years.…”

KIAEI, M.; AMIRI, H.; SAMARIHA, A.; AMANI, N. Effect of nanosilica on thermal, flammability, and morphological properties of WF/rPS-based nanocomposites. CERNE, v. 24, n. 1, p. 59-66, 2018. HIGHLIGHTSThe results showed that the addition of nanosilica increased the thermal stability of the nanocomposite.It was determined that increasing of nano particles to more than a determined level reduced the Limited oxigen index and flammability.The data from thermo gravimetric analysis (TGA) indicated the nanosilica greatly enhanced the thermal stability. ABSTRACTThe present study considered the effect of nanosilica levels on the thermal, flammability, and morphological properties of nanocomposites made of wood flour and recycled polystyrene. To do so, the recycled polystyrene (50%), wood flour (50%), nanosilica (four levels of nanosilica; 0, 2, 4 and 6 phc (parts per hundred compounds)), and maleic anhydride, grafted with polypropylene (at a constant level of 3 phc) were mixed by a twin-screw extruder; then standard experimental samples were made using a hand pressing method. Next, the thermal and flammability properties were measured. The results showed that increasing of nanosilica content to 6 phc by weight increased thermogravimetric analysis (TGA) of nanocomposites; in addition, the limited oxygen index increased. Moreover, scanning electron microscopy (SEM) indicated that an increasing of nanosilica increased compatibility so that better link and adherence was observed among the fiber and matrix material.

“…In the past, numerous research works have been carried out on the effect of various coupling agents on the interfacial adhesion between wood and polymer. These works showed that the main coupling agent used in these composites was branched polyolefin with maleic groups, such as maleic anhydride‐grafted‐polyethylene (MAPE) . Other studies have been done on the use of isocyanate coupling agent in the polymer matrix .…”

The effects of a silane coupling agent such as (N‐(n‐butyl)−3‐aminopropyltrimethoxy silane) on old corrugated container (OCC) fibers, as a recyclable material, were studied on the ultimate strength of the prepared OCC fibers/high density polyethylene composites. Raw materials were mixed in a counter‐rotating twin‐screw extruder and injection molding machine was used to make samples. Various characterization methods, based on ASTM standard, were conducted to evaluate physical properties (water absorption and thickness swelling) and mechanical behavior (tensile, flexural, impact, hardness, and elongation‐at‐break) of the composites. Also, the thermal properties of the specimens were recorded by differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA). Finally the results of the treated samples were compared with the non‐treated and pure polymer specimens. The obtained results showed that increasing coupling agents by a maximum of 2 wt% enhanced mechanical behavior (including flexural and tensile strengths), thermal stability, and increased crystallinity of the composites. Moreover, water absorption and thickness swelling of composite materials declined. Morphological studies by scanning electron microscopy methods (SEM) indicated that fiber pull‐out decreased in treated samples and coupling agent facilitated strong adhesion in fiber/polymer interface. The highest flexural strength and modulus were obtained in composites with 2 wt% silane coupling agent and 30 wt% OCC fibers. POLYM. COMPOS., 39:2054–2064, 2018. © 2016 Society of Plastics Engineers

“…On the other hand, the incorporation of single layered kenaf mat enhanced the value to 10.83 kJ/m 2 , which was found to decrease with further layer (second layer) to 9.73 kJ/m 2 . The value decreased due to the probability of fibre agglomeration, which resulted in stress concentration region which requires less energy for crack propagation [28]. In addition, it was also reported that the impact strength decreased with fibre loading due to weak interfacial bonding between fibre and matrix, which causes micro crack to occur at the point of impact.…”

In this current study, the mechanical, structural and morphological properties of kenaf fibre based polyester composites based on reinforcing arrangement were investigated. Fibres were placed in layers into the resin to enhance reinforcement. A hand lay-up technique was used to prepare the sandwich composite. Composites were characterized by tensile, flexural and impact testing. The structural properties as well as crystalline behaviour were observed by X-ray diffraction analysis. Additionally, the surface of the fractured samples was also examined using scanning electron microscopy to understand the interaction behaviour between the fibres and matrix. Results of the analyses revealed that single layered kenaf mat enhanced the tensile strength by 80%, whereas the double layered improved by 156%, in the presence of a fixed amount of curing agent. The thermal properties of the composites based on double layered kenaf mat were also found to improve compared to the others. The double layered composites can be used as high temperature-sustained roofing materials to replace traditional products.
