The properties of elastomeric materials under thermal aging are crucial for determining the appropriate temperature range and service lifetime. In this study, the effects of thermal aging under various aging conditions on the swelling, hardness, and tear properties of pineapple leaf fiber (PALF)‐reinforced natural rubber (NR) composites with the inclusion of multiwalled carbon nanotubes (MWCNTs) were investigated. The PALF and MWCNT contents were fixed at 30 and 10 parts per 100 rubber, respectively. Thermal aging was conducted at different temperatures (60°C and 80°C) and for different exposure durations (2, 4, and 6 days). The morphologies of the tear‐fractured surfaces were investigated using scanning electron microscopy. Early in aging, the tear strength showed an initial increase followed by a downward trend. In contrast, the aged composites exhibited an increase in crosslink density and hardness with increasing aging duration and temperature. However, the swelling ratio decreased with increasing aging duration and temperature. For instance, when NR30P and NR30P/MWCNT composites were thermally aged at 80°C for 6 days, the swelling ratio decreased to 177.23% and 160.62%, respectively. The addition of MWCNTs remarkably improved the additional crosslinking degree during the aging process, which contributed to a noticeable reduction in crack size, as revealed by microscopic analysis. The findings provide valuable insights for improving the end‐use properties of NR composites.

Thermal aging of natural rubber (NR) composites is the long‐term, irreversible alterations in the composition, morphology, and structure caused by exposure to temperatures normally encountered in service. This has a significant impact on the tensile, wear, and friction properties of the composites. This study aims to investigate the effect of thermal aging on the tensile, wear, and frictional properties of pineapple leaf fiber‐reinforced NR composites with added multiwalled carbon nanotubes (MWCNTs). The variations in tensile and wear properties were monitored for 2, 4, and 6 days of aging at 60°C and 80°C. The morphologies of the tensile‐fractured and worn surfaces were investigated using scanning electron microscopy (SEM). Early in aging, the tensile strength and modulus initially increased, then decreased. The frictional force, coefficient of friction (COF), and specific wear rate gradually increased with aging duration and temperature. After the inclusion of MWCNTs, the tensile strength and COF increased up to 3.21 MPa and 0.94, respectively, under aging conditions of 80°C for 6 days. SEM analysis provided evidence that thermal aging exposure can induce surface cracks, leading to a reduction in the tensile properties of the composites. These findings provide valuable insights into material design for a wide range of applications.

Rubber composites are often used at high temperatures, particularly in practical applications, such as autoclave components, gaskets, and seals. This study investigated the effect of elevated temperatures on the friction and wear properties of pineapple leaf fiber (PALF)‐reinforced natural rubber (NR) composites with the addition of multi‐walled carbon nanotubes (MWCNTs). Commercial NR composites were prepared using a two‐roll mill mixing method, followed by molding. The PALF and MWCNTs contents were fixed at 30 and 10 parts per hundred rubber (phr), respectively. The frictional force, coefficient of friction (COF), and specific wear rate (SWR) were studied in the temperature ranges from room temperature (RT) to 80°C under various applied loads (5, 10, and 15 N). A significant improvement in the wear properties of the composites was achieved with increasing temperature. The results showed that the inclusion of MWCNTs effectively enhanced the wear performance of the composites at elevated temperatures. Overall, this study provides valuable insights into the friction and wear characteristics of PALF‐reinforced NR composites with the addition of MWCNTs, enhancing their end‐use properties for high‐temperature applications.Highlights Improved wear and frictional properties of NR/30PALF composites with MWCNTs. MWCNTs enhance heat dissipation, reducing softening at elevated temperatures. Frictional force and COF decreased with increasing temperature and load. NR/30PALF/MWCNT composites showed smoother surfaces and lower wear rates. Thermal stability and wear resistance of the composites were enhanced.

This study advances the creation of biocomposite materials and serves to reduce and utilize agricultural waste such as pineapple leaf fibers (PALF). In this study, PALF‐reinforced natural rubber (NR) composites with included multi‐walled carbon nanotubes (MWCNT) were analyzed and characterized at various fiber loadings. The PALF content was ranged from 0, 10, 20 to 30 parts per hundred rubber (phr) while the MWCNT content was maintained at 10 phr. A two‐roll mill mixing process followed by molding was employed to fabricate the NR composites. Based on the curing behavior, tribological properties, and morphological analysis, it was confirmed that the hybrid reinforcement of the MWCNT and PALF improved the curing behavior, wear resistance, and morphology of the composites. The wear and friction properties of the composites namely coefficient of friction (COF), frictional force and specific wear rate (SWR) are significantly influenced by the applied loads. The COF of NR/30PALF and NR/30PALF/MWCNT composites is reduced to 0.80 and 0.72 respectively under 15 N of load. Physical properties namely the cross‐link density and swelling behavior of the composites ranged from 3.70 × 10−4 to 5.71 × 10−4 mol/cm3 and 207.81 to 386.17%, respectively. According to the results obtained, the best cure and wear behavior followed by the morphological analysis are observed in NR/30PALF/MWCNT composite. Among the samples tested, NR/30PALF composite exhibited the best performance in both cross‐link density and swelling behavior. It is anticipated that the findings of this study are expected to provide theoretical data for the design and optimisation of high‐performance automotive and footwear applications.Highlights NR/30PALF/MWCNT hybrid composite exhibited the shortest The addition of MWCNT improved the wear resistance of the composites The reinforcement of PALF at 30 phr possessed the lowest swelling ratio and the highest cross‐link density of the composites The addition of MWCNT decreased cross‐link density of the composites

Replacing synthetic fibres with natural fibres as reinforcement fillers in natural rubber (NR) tends to yield eco-friendly bio-composites. This study investigated the tensile and hardness properties, and the thermal behaviour of pineapple leaf fibre (PALF)-reinforced NR composites with and without the addition of multi-walled carbon nanotubes (MWCNT). The fibre content was varied at 0, 10, 20, and 30 parts per hundred rubber (phr) and the MWCNT content was fixed at 10 phr. The surface morphology of the tensile-fractured specimens was examined using scanning electron microscopy (SEM) to identify the rubber-matrix adhesion and tear mechanisms of the fibres in the NR matrix. The results revealed that including the PALF and MWCNT allowed the NR composites to exhibit excellent stretching stress at low elongations. Additionally, the composites displayed enhanced stiffness, further increasing the hardness of the composite, ranging from 46.8 to 62.8 Shore A. However, PALF reduces the thermal stability of the composite, where the initial degradation temperature increases. From the thermogravimetric analysis, the residues remaining in the NR composites ranged from 6-13% at various fibre loadings. Therefore, this study provides valuable insights into the tensile and hardness properties and the thermal behaviour of PALF-reinforced NR composites to improve end-use properties.

Short natural fibres replace synthetic fibres as filler in natural rubber (NR) as they are environmentally beneficial and sustainable. This study investigates the cure behaviour and tensile properties of pineapple leaf fibre (PALF) reinforced NR composites at various fibre contents. The fibre contents are varied at 0, 10, 20 and 30 parts per hundred rubber (phr). PALF reinforced NR composites are prepared using a two-roll mill. Surface morphology of tensile fractured specimens is examined using scanning electron microscopy (SEM). The results demonstrated that the optimum cure time decreases significantly with greater fibre content. The hardness value increases gradually with increasing filler content. The stress-strain graphs show an increasing trend in stress at higher fibre content particularly at low strain regions. On the contrary, the tensile strength reduces when the fibre content is increased up to 30 phr. SEM analysis reveals that the fibre-matrix adhesion is considerably poor due to the fibre pullout phenomenon observed. It is indicated that higher fibre content could be possibly reinforced to NR to achieve high deformation stress at incredibly low strain regions.

This paper reports on the biodegradation and swelling behaviour of cellulose-based plastic incorporation of Pennisetum purpureum (PS), chitosan and gelatine. Cellulose-based plastic (CP) was obtained from chitosan and gelatin; and from the cortex (CPS), pith (PPS), and whole (WPS) of Pennisetum purpureum (PS). The films were prepared by solution casting with untreated, 4, 8, 12, 16, and 20% alkali-treated cellulose of CPS, PPS, and WPS. The ASTM D5988-method was used to conduct the CP biodegradation tests. The swelling behaviour test was performed to measure the swelling percentage for each CP samples in aqueous solution with different pH values. The results reveal that the biodegradation of untreated CPS (60.30%), untreated WPS (49.74%), and untreated PPS (CP) showed the biggest relative weight reduction. CP added with the 8, and 16% alkali-treated cellulose of CPS, and PPS continues swelling in the solution of pH 7 throughout 24 hours of analysis. Increasing the cellulose loading accelerated the biodegradation rate of the bioplastic films. The results also suggest that the CP with the incorporated cortex (CPS) of Pennisetum purpureum (PS), is the most water-resistant in neutral followed by acid and alkali.
