“…It has been a part of man's technology since the first ancient builder used straw to reinforce mud bricks [4]. Composite properties are however dependent on the characteristics of polymer matrix, properties, content and dispersion of the filler and the interface compatibility, of which influence was studied in the past [5][6][7][8][9]. However, finding some alternative sources of natural fibres from post-consumer waste and how they will be processed with the recycled solid waste plastic for the mass production of new products is a new concept, driven by the circular economy business model.…”

This study investigates the mechanical, thermal and morphological properties of rHDPE (Recycled High Density Polyethylene) and a mixture of rPE HD/LD (High and Low Density Polyethylene), both reinforced with rNP (Reclaimed Newsprint Paper) fibres. To enhance the composite properties, the addition of highly grafted maleic anhydride polyethylene wax, as CA (Coupling Agent), and semi crystalline copolymer of propylene and ethylene, as IM (Impact Modifier), was included into the material formulation by a twin-screw extruder. Mechanical and morphological properties were studied on tensile test specimens, prepared by injection moulding, by tensile testing machine and SEM (Scanning Electron Microscope), respectively. Thermal properties, i.e. melting and crystallization behaviour, were investigated by DSC (Differential Scanning Calorimetry). Mechanical analysis showed that the addition of rNP in both composites increased the young modulus and significantly decreased the elongation at break. The DSC results revealed that the addition of the rNP in the rHDPE matrix led to a substantial decrease of crystallinity, which consequently affects the tensile strength of the composite (17 MPa) in contrast to the neat rHDPE (25 MPa). On the contrary, fibre addition in rPE HD/LD matrix had no specific impact on the crystallinity index, but did contribute to the increased tensile strength (26 MPa) when compared with neat rPE HD/LD (16 MPa). SEM photomicrographs of the impact fracture surfaces demonstrated a solid adhesion bond between the natural fibres and the rPE HD/LD matrix. Reclaimed newsprint fibres can thus be considered as a perspective alternative to the inorganic fillers in the rPE HD/LD composite.

“…From the differential scanning calorimetry (DSC) analysis results revealed that the addition of the DPF into the HDPE matrix has increased the crystallization temperature. However, the crystallinity index of the composites at all DPF loadings was lower than the neat HDPE, which could be related to the hindered movement of the HDPE molecular chains by the presence of the fibres [15]. The comparison study of using extracted fibre from waste and residue of Malaysian's palm oil (OPF) with Japanese type cedar thinned wood fibre on the tensile and impact properties reinforced PP was investigated.…”

Presently, the application of natural fibres widely gains attention from academia and industries as an alternative material in the composite system. The introduction of the hybrid composite using natural and synthetic fibres is extensively investigated on the static mechanical properties. However, the investigation on the high strain-rates effect is less reported due to the difficulty of the experimental set-up as well as the limitation of dynamic testing apparatus. The split Hopkinson pressure bar (SHPB) was utilised in this present study to characterise the dynamic mechanical properties of the hybrid composite between E-glass with jute fibres at three different strain rates of 755, 1363, and 2214 s−1. Results showed that the dynamic compression stress and strain of the tested samples significantly influenced by the value of strain rates applied. The E-glass/jute sample exhibited the strain-rate dependent behaviour, whereby the higher dynamic mechanical properties were recorded when the higher strain rates were imposed. The difference between maximum dynamic stress was 12.1 and 23.9% when the strain rates were increased from 755 to 1363 s−1 and 1363 to 2214 s−1, respectively. In terms of compressive strain, the maximum compressive strain was recorded when the lower strain rates were imposed during testing.

“…In recent years, natural fibers have been widely studied by experts as industrial materials such as mengkuang fibers, palm fibers, akaa (corypha) fibers, king pineapple leaf fibers, coconut fibers, carica papaya fibers, albizia amara fibers, and juncus effuses L fibers [1][2][3][4][5][6][7][8][9]. This study discusses the treatment of Sago fiber (SF) using acetic acid in liquid smoke from coconut shell which is more eco-friendly than other alkali treatment.…”

“…Previous studies attempted various treatments on natural fibers including immersion in solutions (NaOH, KMnO4, H2O2, and seawater), heating with turmeric solution, and steaming [2,3,6,[10][11][12][13]. The treatments had altered physical properties of fibers, such as lignin level reduction from coconut husk by immersion in NaOH, cleared and shaped grooves by immersion in KMnO4 and H2O2 [3].…”

This study aims to identify the effect of liquid smoke treatment on surface morphology and tensile strength of sago fiber (SF), including chemical reactions during the treatment. The proposed study is divided into two steps, fiber treatment and property tests. The first treatment, SF was immersion in the liquid smoke solution for 1, 2, 3, 4, and 5 hours, then dried for 1 hour which then characterized SEM, universal machine testing machine, X-Ray diffractometer (XRD), and Fourier transform infrared spectrometer (FTIR). The acetic acid in liquid smoke reacts with fiber to form fiber-liquid and H2O compounds. The heating process degrades H2O content in fibers and decomposes C and C elements to close together forming strong chemical bonds so that the fiber morphology become rough, porous, grooved and increasing the tensile strength of the fiber. But excessive heating treatment makes fibers more fragile because the H2O elements degrade too low. Dominant percentage of SF crystallization occurred after 4 and 5 hours, 64.7 and 66.9 %, respectively among other durations, a significant increase of tensile strength 50.813 MPa was achieved by 1-hour immersion in liquid smoke. Hence, as alternative to improve the mechanical characteristics of SF, immersion in liquid smoke should be applied. Furthermore, studies of similar treatment on other natural fibers can also be considered in the future.
