“…Furthermore, date palm fibers are feasible to be employed in the automotive industry because of their good specific extensional stiffness to cost ratio . Also, industrial gears can be made from cotton‐reinforced plastic . However, cellulosic fiber/epoxy composites as sisal, jute, and cotton/epoxy composites have a great potential in light applications requiring high toughness and sound absorption .…”

This article provides an experimental investigation into the crashworthiness of carbon–jute–glass reinforced epoxy circular composite tubes. The test specimens were fabricated of 6 layers with different stacking sequence using wet‐wrapping process and tested under uniaxial quasi‐static compression loading up to complete crushing. The effects of hybrid reinforcement, stacking sequence, and relative reinforcement amounts on the energy absorption capabilities and failure modes were studied. Also, the crush load–displacement response, initial crushing failure load, total energy absorption, specific energy absorption, average crushing load, and crushing force efficiency were determined and discussed. The scanning electron microscope study was considered to analyze the failure modes of the crushed specimens. Results indicate that specimens' failure modes and energy absorption capabilities were highly dominated by the reinforcement combinations and plies stacking sequence. Also, hybrid carbon–jute–glass reinforced epoxy composite tubes have the potential to be used as energy absorbers as compared to jute‐reinforced epoxy composite tubes. The JGC composite tube has a higher load carrying capacity and energy absorption capability compared to other hybrid composite tubes, so it seems to be the best appropriate choice for energy absorbing devices.

“…In particular, works on thermoplastic matrix composites reinforced with cotton fibres elicited some potential for these materials [1,2]. Thermogravimetric studies of cotton fibres suggested that cellulose decomposition would occur between 240 and 400°C, with 90% of the process taking place above 300°C: this is compatible with the maximum temperatures applied for polypropylene injection moulding, which are around 190°C or slightly above [3] Some applications have been proposed for cotton fibre reinforced polymers for gear materials, as a replacement for phenolic/paper laminates, for their excellent properties in cleavage fracture [4]. This has suggested some possible use for these materials in the field of tribology [5] and also, due to their unexpected wear resistance, as the reinforcement of fly-ash based geopolymers [6].…”

“…In the work of Senthilvelan and Gnanamoorthy [9], by incorporating 20% short glass and 20% carbon fiber to the Nylon 6/6 gear, the damping capacity of the composite gear has been decreased, 2 International Journal of Manufacturing Engineering thereby influencing the noise and heat generation during service. Hirogaki et al [10] used cotton fiber plain woven filled phenolics resin laminate as the gear material to study the tooth root stress resulting from bending movement under running conditions; the results revealed that the strength of a tooth with a filled fiber angle of 45 ∘ is at the lowest when the load is applied to the tooth tip. In addition, Mendi et al [11] found that reinforcing the polypropylene gear tooth with metallic wires, subsequently generating a residual compression stress in the structure of the gear tooth, increases the number of cycles of fatigue failure and enhances fatigue strength.…”

Shrinkage behavior is a crucial problem in manufacturing plastic molded gear. This is because it negatively affects the dimensional stability and accuracy of the involute profile, as well as the concentricity, roundness, tooth spacing uniformity, and size of the gear. By integrating the Taguchi robust design, Grey relational analysis, and principal component analysis, we investigated the dimensional stability related to the shrinkage of tooth thickness, addendum circle, and dedendum circle of molded gear via the optimization of processing parameters and glass fiber reinforcement. The results revealed that the optimal combination of the processing parameters of the molded gear to achieve minimum shrinkage is melt temperature of 260°C, packing pressure of 60%, packing time of 5 s, and cooling time of 30 s. The melt temperature showed the highest comparability sequence among the four key process parameters examined, followed by packing pressure, cooling time, and packing time. Meanwhile, the presence of glass fibers induced higher deviations of tooth thickness, addendum circle, and dedendum circle than those of the unfilled polyamide 6 gears.
