“…Later, the extruder was used to blend and extrude the material out of the extruder by a valve to collect the process mixture for the next stage, as shown in Figure 6 for the material preparation process. The control sample was also prepared by blending pure PLA (0 wt%) using the same conditions as done in several other composite studies [49,50]. Due to the capabilities of the extruder that produces limited quantities of the mixtures, the extruded composites were chopped into small pieces (~1 g) and thermally compressed for 5 min using a Carver's press (Carver™ Lab Presses) under 34.47 MPa pressure at 190 • C to produce composite sheets that were used for the mechanical investigation stage.…”

Due to the significant properties of silica, thermostatics can be enhanced using silica-additives to maximize the quality of polymer compounds and transform plastics into tailored properties. The silica additives can enhance the handling and quality performance of composites and thermoplastic polymers due to their diverse potential. Besides, using silica as an additive in different characteristics can allow granulates and powders to flow easily, minimize caking, and control rheology. On the other hand, the eruption of 3D printing technology has led to a massive new waste source of plastics, especially the polylactic acid (PLA) that is associated with the fused deposition modeling (FDM) process. In this paper, the impact on the mechanical properties when silica is mixed with waste PLA from 3D printing was studied. The PLA/silica mixtures were prepared using different blends through twin extruders and a Universal Testing Machine was used for the mechanical characterization. The result indicated that increasing silica composition resulted in the increase of the tensile strength to 121.03 MPa at 10 wt%. Similar trends were also observed for the toughness, ductility, and the yield stress values of the PLA/silica blends at 10 wt%, which corresponds to the increased mechanical property of the composite material reinforced by the silica particles. Improvement in the mechanical properties of the developed composite material promotes the effective recycling of PLA from applications such as 3D printing and the potential of reusing it in the same application.

“…Cellulose addition for the reinforcement of WPCs were also investigated and significant improvements were obtained [18]. Pesman and Tufan [19] studied the effects of CaCO3 coated wood free paper usage as filler on water absorption, mechanical and thermal properties of cellulose-high density polyethylene (HDPE) composites. They concluded that calcium carbonate presence had increased the water resistance of cellulose fiber-HDPE composites [19].…”

In this study the effects of ink (offset and toner) presence on the mechanical, physical, morphological and thermal properties of newspaper-and office paper fiber-plastic composites were investigated. Printed and unprinted newspaper and office paper fibers were mixed with recycled polypropylene at 50 % by weight fiber loading. The samples were produced with extrusion and compression moulding. The mechanical properties, water absorption and thermal resistances of unprinted and printed newspaper-and office paper fiber-polypropylene composites were compared. In addition, samples were characterized with Fourier transform infrared spectroscopy, and scanning electron microscopy. The obtained results showed that ink presence in the fiber matrix enhanced the water resistance and mechanical properties of fiber plastic composites. Due to ink formulation and fiber characteristics, better results were obtained with printed office paper fiberplastic composites than with printed newspaper fiber-plastic composites. Scanning electron microscopy investigation also confirmed the good interaction between polypropylene and toner-printed office paper fiber. Moreover, differential scanning calorimetry measurements showed that higher crystallization (χcor) values on printed office paper-and newspaper fiber-plastic composites. This work demonstrated that undeinked waste paper fibers could be effectively used as the reinforcing filler in thermoplastic matrices.

“…Natural fibres are inexpensive, also possess some unique properties such as low density to easy to be processed, abundance, no tendency to corrosion and most importantly they promote eco-friendly materials, which are safe to be handled [4,5]. Among popular natural fibres are kenaf, hemp, bamboo and oil palm have widely been discovered by worldwide researchers especially in hard matrix composites such as epoxy and polyester to seek its potential as reinforcements in composite materials.…”

Due to high flexibility and elasticity, silicone rubber has been widely used in many applications especially in medical and industrial sectors. However, pure silicone rubber experiences weak tensile strength and this can be improved via filler addition. Therefore, this paper aims to produce a new type of silicone biocomposite (Arenga pinnata-silicone biocomposite) and assess its mechanical properties, physical properties and morphological characteristics. The effects of Arenga pinnata filler on the silicone rubber are investigated by comparing the mechanical properties between pure silicone rubber and 12 wt.% Arenga pinnata-silicone biocomposite. Uniaxial tensile test was conducted on these soft materials to obtain stress-strain data, which then converted into engineering stress-stretch (σE-λ) data. These experimental data were fitted to Neo-Hookean and Mooney-Rivlin models to acquire the material constants. Its physical characteristic was studied via density test and the morphological surface on the break surface was examined using Scanning Electron Microscope (SEM). The average maximum tensile strength of the specimen with the addition of 12 wt.% Arenga pinnata filler is found to be 0.65 MPa. This signifies a decrease of its strength compared to pure silicone rubber (average maximum tensile strength = 0.85 MPa). However, in contrary, it is found that the presence of Arenga pinnata fibre has increased the stiffness and density of the silicone rubber. When comparing to experimental data, it could be observed that both Neo-Hookean and Mooney-Rivlin models could mimic better the elastic behaviour of the 12 wt.% Arenga pinnata-silicone biocomposite compared to pure silicone rubber. Observing the SEM images, no agglomerations of Arenga pinnata filler can be seen thus conforming good dispersion of the filler. The images also show good fibre adhesion between the filler and the matrix. Therefore, it can be concluded that the addition of Arenga pinnata filler has enhanced properties of pure silicone rubber. In addition, this study promotes the benefits of utilising natural fibres as fillers in composite materials.
