“…The cause for the increase in water absorption seen in this study could be because of the occurrence of micro cracks and ber's nature to absorb water and voids. The same pattern of results was observed by many researchers during their previous studies (Gupta 2020) (Ramesh et al 2020) (Prakash et al 2018) ). The composite samples fabricated with epoxy and nettle ber proportion was 75:25 and they showed higher water absorption rates than 85:15, 90:10 and 95:5.…”

This paper discusses on fabrication, testing and evaluation of delamination factor of nettle fiber based composites for low duty applications. The randomly oriented nettle fibers were used to fabricate the biocomposite by conventional hand lap up technique. Epoxy and Nettle based composite plates were developed by varying fiber weight percentage from 5% to 25%. The flexural, tensile, impact, chemical resistance and water absorption rate of developed nettle fiber based biocomposite were examined for different fiber weight fractions in the randomly oriented patterns as a unique and innovative attempt. During the investigation, flexural strength and tensile strength were improved up to 20 wt% of fiber addition and then it was decreased. This resulted in a continuous rise in impact strength with an enhancement in fiber wt. %. The influence of fiber weight percentage on water absorption and chemical resistance of fabricated composite was examined in different environments. The result showed that the nettle fibers can be used as an essential reinforcing material to design and fabricate mechanical and structural members for low duty application. The chemical behavior of nettle based composite was studied by the FTIR spectroscopy method and the presence of chemical functional group was confirmed. The drilling behavior of developed nettle/SiC/epoxy hybrid composites was evaluated by consider cutting process parameters like feed rate (0.125, 0.212 and 0.3 mm/rev), spindle speed (400, 600, 800 rev/min) and drill diameter (4, 6, 8 mm). Analysis of variance was used in designing experiments for the current investigation. Feed rate was found to be a very impressive factor in influencing the delamination factor.

The fiber composite plays a vital role in various applications in the current scenario. Natural fibers provide the desired advantages over synthetic fibers. Fiber composites deliver the exploration of durable, degradable, and lightweight materials. In several industrial sectors, transportation of materials from one place to another place is required. Materials like thermocoal boxes and iron boxes are inefficient in strength, weight, and cost. In order to overcome these, natural fiber-based composites, which give both strength and durability with low weight and cost, are chosen. This work explains the sample preparation using Arhar powder with an addition of reinforcements using the hand lay-up method by obeying the ASTM standards. To analyze the performance of the sample specimen, properties evaluated like Compression, Flexural, and other tests were conducted. GRA (Grey-Relational Analysis) with PCA (Principal-Component Analysis) was employed to carry out the most significant parameters, the most significant factor, and the weights of optimal parameters. Based on the output responses, it is experiential that the most effective parameter and best combination factor at Acrylonitrile butadiene styrene (ABS-4%), Guar Gum (8%), and Carboxy methyl cellulose (CMC-8%) with the values of 83.12 MPa compression strength, 61.70 MPa tensile strength and 0.249 joules of Impact strength.

Hybrid polymer composites are more attractive because of their light in weight, more robust and rigid (in the direction of fiber) than traditional or unreinforced polymers with the added advantage of having their design and form adapted to suit the specifications of a particular application by the combination of the right choice of the materials. Reinforcement in a polymer hybrid composite can be fiber, filler, or fiber& filler together. Integrating reinforcement into polymers can lead to significant growth in the wear characteristics and mechanical properties of the polymer. Nevertheless, in applications wherever interaction by the liquid medium is inevitable, the mechanical properties and wear characteristics of hybrid polymer composites undergo degradation, which is a generally seen phenomenon since liquid medium acts as a plasticizer. This study aims to provide detailed information on the mechanical and tribological effects of hybrid polymer composites. More emphasis is given towards degradation of mechanical properties such as tensile strength, bending strength, and degradation of wear characteristics like erosion wear rate, and respective failure characteristics were analyzed under different environments such as water, kerosene, saline, sub-zero conditions.
