To demonstrate the upcycling of thermoplastic waste with good thermo‐physical properties, high density polyethylene (HDPE; 80 phr) and polyvinyl chloride (PVC; 20 phr) are mixed as the matrix using maleic anhydride (MAH) reinforced with unmodified and modified date palm fibers (DPFs; 30 phr). The effects of in situ grafting of MAH onto the DPFs‐HDPE‐PVC composites upon the resultant thermo‐physical characteristics are investigated and analyzed via Fourier transform infrared spectroscopy and scanning electron microscopy. Thus, the effective compatibilizing of both the HDPE‐PVC component and the grafted HDPE‐PVC blend with the modified DPFs are confirmed. In addition, the results of dynamical mechanical analysis and differential scanning calorimetry indicate that the glass transition temperature (Tg) of the composite is enhanced by the incorporation of modified DPFs. The thermal, mechanical, and water uptake properties of the composites are also improved. Rheological analysis at low frequency reveals that the introduction of hydrolyzed DPFs results in a higher complex viscosity (1.94 × 106 Pa s) and storage modulus (119,844 MPa) for the obtained composite (designated G‐Hydro). Overall, the G‐Hydro composite exhibits the best performance, making it ideal for a variety of construction and building purposes.

“…The increase in tensile strength is attributable to the enhanced adhesion between the fibre and matrix, which permits greater stress transmission by bonding to the fibres. Eszer and Ishak (2018) claim that in the presence of MAPP, which interacted with the hydroxyl group on the surface of the kenaf fibre, a good stress transmission interface is generated due to probable covalent contact between the anhydride and hydroxyl groups of the kenaf, as well as chain tangling between the MAPP and PP chains [7]. Due to that reason, additional MAPP is proof that the tensile strength improved by around 28% compared to the sample without additional MAPP.…”

“…Kenaf fibres is preferably to be choose by the industrial as its potential to be a polymer reinforcements in the natural fibre composite industry. Numerous previous studied had claimed that mechanical strength and thermal properties of kenaf composite are superior to other type of natural fibre polymer composites, thus regarded as a suitable applicant for high-performance kenaf fibre polymer composites [6][7][8].…”

In a competitive product market, manufacturers ought to utilize eco-friendly materials to reduce the environmental impact of their products. Kenaf (Hibiscus cannabinus) is an annual plant that produces bast fiber and develops rapidly. These fibers have excellent properties and could serve as ideal reinforcing fillers for wood-based products. This study aims to investigate Maleated Polypropylene (MAPP) as a coupling agent for Kenaf fiber (KF)/Polypropylene(PP) composite. Three distinct composites were created using the following ratios: Sample 1 (Kenaf 20g: PP 180g), Sample 2 (Kenaf 10g: PP 180g: MAPP 10g), and Sample 3 (Kenaf 15g: PP 180g: MAPP 5g). All materials are mixed and extruded in a single-screw extruder at 185 to 200 °C at 50 rpm. A granulator is then utilized to palletize the samples. For testing, tensile and impact testing is conducted for mechanical properties, water absorption for physical properties, and Scanning Electron Microscopy (SEM) for morphological characterization. The thermal characteristics of the composites are analyzed using thermogravimetric analysis (TGA). The results indicate that the KF/PP composite with a coupling agent has a higher tensile strength with a value of 29.3 MPa compared to the KF/PP composite without a coupling agent with a value of 22.4 MPa. Water absorption of composite with coupling agent was also less than without coupling agent with a value of 1.05% and 1.31% respectively.

“…Since the natural fibers are abundant, ecological, economical, light and have high specific mechanical characteristics, they have been widely used as reinforcement in natural fiberpolymer composites with applications in paper and packaging, construction and automotive industries [1,2]. Thus, biocomposites based on natural fibers and especially thermoplastic polymer blends are being widely investigated to minimize the plastic waste problem [3][4][5]. The mechanical properties of these composites primarily depend on the elastic behavior and strength of fibers, fiber network, matrix and interfacial bonding [6][7][8][9][10].…”
