Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In the ongoing researches, many attempts have been made to produce such a lightweight composite, possesses high hardness, high strength and is more reliable. In this work, the hybrid polymer composite has been fabricated using the industrial particulate waste i.e. Linz Donawitz (LD) sludge (5, 10, 15 and 20 wt%), woven glass fiber as reinforcements and epoxy as a binder matrix. ASTM Standard has been followed to evaluate properties like micro-hardness, flexural strength, tensile strength and compressive strength. The sliding wear response of the newly manufactured polymer matrix composites is estimated using a pin-on-disk sliding wear tester. Sliding wear assessments are prepared in accordance with the experimental design, which is based on Taguchi’s L25 orthogonal array, in order to identify prominent elements influencing wear rate. Scanning electron microscopy (SEM) is carried out to analyze the sliding wear characteristics of the fabricated composites. This investigation shows that with increase in LD sludge content, the micro-hardness, tensile, compressive and flexural strengths of the composites increased significantly in comparison to the glass–epoxy composite. The LD sludge content is observed to be the most weighted control factor that affects the sliding wear rate of the composites followed by sliding velocity. From SEM micrographs it is understandable that with increased sliding velocity and applied load, the polymeric resin softens and results in deeper wear tracks under the presence of low filler content. Whereas in composites with higher filler content swallow wear tracks are observed.
