In the present work, the water absorption behaviour of Indian ramie/epoxy composites and its effect on mechanical and tribological behaviour have been investigated. The composites fabricated using the hand layup technique were immersed in distilled water at room temperature for water absorption test for a period of 120 days. Mechanical and tribological properties were evaluated for composites with 30 wt.% ramie fibre loading. The results obtained were compared with that of the dry specimen. Mechanical properties including tensile strength, flexural strength, impact strength and hardness were evaluated. A reduction of 16.85%, 13.63%, 21.02% and 3.33% in tensile strength, flexural strength, impact strength and hardness was observed after the water immersion, respectively. Friction and wear behaviour was also investigated for water immersed specimen. Frictional coefficient decreased for the developed composites and wear performance reduced after the water absorption test. Fractured surfaces post to mechanical testing and worn out surfaces of tribological test samples were examined by scanning electron microscopy. The weakening of fibre–matrix interface was observed in the scanning electron microscopy micrographs, which appears to be the main cause for the degradation of properties.

“…There are other factors that influence in the enhancement of the properties of the composite such as geometry, i.e., shape, size, and distribution of the reinforcement (Mahesha et al, 2019;Vidyashri et al, 2019;Yashas Gowda et al, 2018). The other factor that influence the properties of the composites is the alignment of the fibers, which results in the optimum tensile, flexural, and impact properties (Balasundar et al, 2019;Dinesh et al, 2020;Mahesha et al, 2017;Pickering & Le, 2016). Composite materials can be processed by various manufacturing techniques such as spraying, lay-up, resin transfer molding, compression molding, pressing, and stir casting.…”

Natural fiber composites expected to be in great demand in the coming years due to increased consumer awareness to reduce the waste and environmental pollution. Bagasse fibers available in plenty as an agro-residue and bio composites derived from such renewable resources offer potential for scale-up and value addition. This review provides an insight on current research trends on development and characterization of bagasse-based composites. Various chemical treatment methods and processing techniques used to improve the mechanical, thermal, acoustic, and aging properties of sugarcane bagasse reinforced composites are summarized in the review.

“…23,26 Grewia serrulata bast fiber and its chemical treatment shows increasing pattern in the mechanical properties (tensile strength, flexural strength) of the treated fiber reinforced composite. 27 Weight fraction and fiber length are the two important factors which has significant effect on the tribological and mechanical properties of the composite. 28,29 The performance of NFCs depends on various factors such as cellulose content, chemical composition, mechanical properties, physical properties, microfibrillar angle, aspect ratio, and interaction between fiber and polymer, 30,31 higher the cellulose content better will be the strength, while it is opposite for lignin and microfibrillar angle.…”

This research paper investigated the hardness and tribological performance of novel Grewia optiva/Basalt fiber reinforced hybrid polymer composites. Two different configuration of hybrid composite that is, woven and chopped fiber reinforced composite are considered for the study. The chopped fiber configuration of the composite is further divided into two types based on fiber length and wt%. The fiber lengths studied are 6 and 12 mm while the wt% studied are 0, 6, and 12 wt%. Woven fiber reinforced composite is divided into five configurations based on wt% of G. optiva fiber with 0, 3, 6, 9, and 12 wt%. In all configurations, maximum fiber content of 12 wt% is maintained. B6/GO6 composite exhibits minimum specific wear rate and maximum hardness among all the compositions. Wear experimental results are analyzed by Taguchi optimization technique and based on the five levels and four control factors (sliding velocity, fiber loading, sliding distance, and normal load) L25 partial orthogonal array was suggested for the woven fiber reinforced composites. Fiber content is the main control parameter for hardness testing and L9 orthogonal array was suggested according to four control factors and three levels.
