“…The range of values of “η” reflects the semi-ductile behavior of the composite, which also supplements the results presented in Figure 12. Similar results were also shown by Pradhan et al 16 and Prakash et al 17 while working with Eulaliopsis Binata fiber and Rubber-wood particulates epoxy composites respectively. Thus, the erosion efficiency values obtained from the experimental findings revealed semi-ductile behavior of target specimens.…”

“…Again, a noticeable shift in the erosion characteristics from semi-ductility to semi-brittleness was noticed with increase of particle velocity, which also coincided with the erosion efficiency data. The erosion properties of SN (Syngonanthus nitens)/epoxy composite with varying weight percentages (10 wt.%, 20 wt.%, 30 wt.%, and 40 wt.%) were examined by Prakash et al 17 The experimental data showed that the composites exhibited the highest wear rate at impact angles of 45° and 60°, corresponding to lower and higher particle velocities, respectively. These findings reflect the semi-ductile behavior.…”

The concern for the environmental hazards due to rapid utilization of non-biodegradable resources has persuaded the researchers to develop eco-friendly materials with noble categories of plant-based fibers and fillers. In view of this content, an effort has been initiated in the present work to explore the retrospective effect of PSP (Pistachio shell particles) on both mechanical as well as erosive wear performances of KG (kenaf/glass/kenaf/glass) hybrid polyester laminated composite. The KG laminate with different filler concentration, that is, 0 wt%, 1 wt%, 3 wt%, and 5 wt% were fabricated by using hand-lay-up technique and the mechanical properties of these laminates were determined by performing tensile, flexural and impact tests as per ASTM standard. A higher tensile value of 127.35 MPa with modulus of 7.658 GPa and hardness of 21.35 HV was obtained at 5 wt% reinforcement of PSP filler whereas 3 wt% filler reinforcement responded an optimum flexural strength of 112.42 MPa with modulus of 5.214 GPa and impact strength of 75.59 KJ/m2. To evaluate the wear performance of this laminates against high-speed solid particle, erosion wear test was carried out at different striking velocity and impingement angles. A noticeable reduction of 12.63% in wear rate was found due to increase with concentration PSP filler from 0% to 5 wt%. Further, the η (erosion efficiency) was also found to be limited within the range of 5.94% to 32.98%. From micrographic analysis of the fracture surface, micro-ploughing and micro-cutting actions were found to be most predominant primary wear mechanisms.

“…The composite specimen's theoretical density and void fractions were obtained using Equations () and (), and the results are reported in Tables 1 and 2 for untreated and treated fiber composites. The fabricated composites having void fractions (≤4%) were selected for mechanical testing, as suggested by Prakash et al [ 46 ]

\frac{1}{ρ_{th}} = \frac{W_{af}}{ρ_{af}} + \frac{W_{e}}{ρ_{e}}

φ_{normalv} = \frac{ρ_{th} - ρ_{act}}{ρ_{th}} \times 100

The aim of the research work was to fabricate the short Agave lechuguilla (AL) fiber-reinforced epoxy composite and to improve its mechanical strengths. In order to do that, a single fiber pullout test was conducted to evaluate the critical length of the AL fiber and its interfacial shear strength (IFSS) in epoxy resin. To improve the IFSS, AL fibers were treated with varying concentrations (5%, 10%, and 15%) of NaOH, and it was found that 5% NaOH treatment exhibits excellent tensile strength and IFSS. Fibers treated with 5% NaOH and untreated fibers were used separately as reinforcement materials varying between 10% and 40% with a 10 wt% step in composites fabrication. The tensile strength, flexural strength, and modulus of the composites were evaluated as per ASTM standards. The results reveal that the composites reinforced with 30 wt% of untreated AL fibers give maximum tensile and flexural strength. When 5% NaOH-treated fibers were used as reinforcement instead of untreated fibers, their tensile and flexural strength improved by 8.14% and 7.88%, respectively. To investigate the fracture mechanism of the tested samples, the specimen's fractured surfaces were analyzed using scanning electron microscope and reported in this paper.

Abaca is a high-strength natural fiber whose tribological behavior in epoxy polymer composite is unexplored to date. This paper aims to study the mechanical and dry sliding wear behavior of abaca fiber (A) and glass fiber (G) reinforced epoxy laminate composites with various stacking sequences. Symmetrically oriented laminate composites were fabricated in different stacking sequences (AAAA, AGAG, AGGA, and GAAG) using hand lay-up technique. Mechanical characterization is carried out as per ASTM standards. It is found that GAAG hybrid composite possesses maximum tensile strength (101.05 MPa). Meanwhile, AGAG composite shows maximum flexural strength (190.15 MPa) and interlaminar shear strength (5.97 MPa). Abrasive wear behavior of the composites is investigated by performing the test on a pin-on-disc tribo tester as per the ASTM G99 standard under dry sliding conditions. Tribological results indicate that hybridization of abaca and glass fiber into an epoxy matrix enhances the wear properties significantly. Maximum wear resistance is observed with AGGA-layered hybrid composite. The reduction in volumetric wear of AGGA composite is found to be lower than neat epoxy by 86.51%. However, the frictional force of AGGA composite increased by 54.17%. Furthermore, the morphology of fractured and worn-out surfaces is studied using a scanning electron microscope. It is inferred that failure is mainly due to the development of micro-cracks on both fiber and matrix, combined with fiber fragmentation, plowing, and debonding.
