The purpose of this study is to evaluate the effectiveness of a low-cost and environmentally friendly chemical modification on sisal fiber reinforced epoxy composites. The results showed that the chemical treatment improved the morphological properties of the fibers, reduced the hemicellulose and lignin contents, and enhanced the thermal, mechanical, tribological, and morphological characteristics of the composites. The sodium citrate treatment was found to be more effective than the stearic acid treatment in improving the mechanical and tribological properties.
The purpose of the present work is to assess the effectiveness of a low-cost and environmentally friendly chemical modification of sisal fibers based on the usage of sodium citrate (SC) and stearic acid (SA) on the thermal, mechanical, tribological and morphological characteristics of sisal fiber reinforced epoxy composites (SREC). Scanning electron microscopy (SEM) was used to investigate the morphological properties of the sisal fibers, which demonstrated that the chemical treatment eliminated the contaminants from the fibers' surface. The reduction of hemicellulose and lignin contents of the fiber was confirmed by Fourier transform infrared (FTIR) analysis following both chemical treatments. Thermal stability of the treated fibers showed a slight reduction as revealed by Thermogravimetric analysis (TGA) and Differential scanning calorimetry (DSC). Mechanical properties like tensile, flexural and inter-laminar shear strength showed appreciable improvement for the SA treated SREC (8.05%, 8.50% and 29.42%) and SC treated SREC (23.27%, 13.13% and 51.02%) when compared to untreated SREC. Furthermore, the tribological behaviour of the composites reinforced with treated fibers showed improved wear resistance and frictional properties in comparison to untreated composites. To better understand the fiber/matrix adhesion, morphological examinations of fracture and worn surfaces of composite samples were done using SEM. The test results suggest that the sodium citrate treatment is superior to the stearic acid treatment in improving the composites' mechanical and tribological properties.

Dry Sliding Wear Behavior of Chemically Treated Sisal Fiber Reinforced Epoxy Composites

Sudhakar Behera, Rakesh Kumar Gautam, Sunil Mohan, Arghya Chattopadhyay

Summary: The research investigated the effect of fiber surface treatment on sisal fibers and their epoxy composites, showing improvements in surface roughness, crystallinity, and thermal stability of chemically treated fibers. The wear resistance of chemically modified SFREC was increased compared to untreated SFREC, with the best wear properties demonstrated by alkali-treated SFREC. Applied load and sliding distance were observed to have the most defining effect on wear volume loss of SFREC according to ANOVA findings.

Hemp fiber surface modification: Its effect on mechanical and tribological properties of hemp fiber reinforced epoxy composites

Sudhakar Behera, Rakesh Kumar Gautam, Sunil Mohan, Arghya Chattopadhyay

Summary: This research investigated the effects of sodium carbonate and hydrogen peroxide treatment on hemp fiber reinforced epoxy composites (HFREC), focusing on water absorption, mechanical, and tribological properties. The results showed that both chemical treatments improved water resistance and mechanical properties of the composites, while also enhancing wear and frictional properties. The best overall performance was observed in peroxide treated HFREC, as confirmed by SEM images of worn and fractured surfaces.

Polylactic acid and polyhydroxybutyrate coating on hemp fiber: Its effect on hemp fiber reinforced epoxy composites performance

Sudhakar Behera, Rakesh Kumar Gautam, Sunil Mohan

Summary: This research investigates the influence of biodegradable polymer coatings on hemp fiber and hemp fiber reinforced epoxy composites. The results show that the coatings improve the surface roughness and crystallinity of the fibers, enhancing the interfacial adhesion with the epoxy matrix. The coatings also improve the mechanical and tribological properties of the composites.

Mechanical and tribological properties of chemically modified jute/epoxy composites

Sudhakar Behera, Rakesh Kumar Gautam, Sunil Mohan, Arghya Chattopadhyay

Summary: The purpose of this work is to evaluate the effectiveness of low-cost and environmentally friendly chemical modification on jute fibre-reinforced epoxy composites (JFREC) using sodium hydroxide (AT), sodium carbonate (ST), and sodium hydrogen carbonate (SHT) in terms of morphology, water absorption, mechanical, and tribological characteristics. Results showed significant improvement in mechanical properties such as tensile strength, tensile modulus, and impact strength for AT JFREC (38.08%, 30.56%, 31.66%), ST JFREC (70.03%, 33.06%, 41.30%), and SHT JFREC (24.69%, 8.88%, 22.61%) compared to untreated JFREC. The study also confirmed that the chemical modification improved fibre-matrix adhesion, leading to enhanced water absorption resistance and tribological properties of the modified JFREC. The improved mechanical and tribological properties make the chemically modified JFREC potentially applicable in automotive and packaging industries.

Mechanical, water absorption and tribological properties of epoxy composites filled with waste eggshell and fish scale particles

Sudhakar Behera, Rakesh Kumar Gautam, Sunil Mohan, Anupam Tiwari

Summary: Egg shells and fish scales can be used as filler materials to enhance the properties of polymer composites. The addition of these fillers improved the water absorption, wear resistance, and tensile modulus of the composites. However, it also reduced the tensile and impact strength. Among all the tested composites, the hybrid composite showed the best performance in terms of flexural strength and modulus.
