Reviewer 2 Report
The research work named ‘Analysis of Elastic Properties According to the Aspect Ratio of 2 UHMWPE Fibers Added to PP/UHMWPE Composites’ seems really interesting and the article is quite interesting and the research direction does some research novelty and exploration. The results are reasonably good and I recommend for the acceptance of the manuscript after addressing the minor corrections to further improve the article:
1. The novelty of the work has to be described in the introduction section, how different from other reported works.
2. The abstract part must be result oriented, with increase/decrease in percentages of the properties.
3. In the introduction section applications of synthetic fibers needs to be mentioned, mainly glass fibers and carbon fibers should be referred see the following works related to that
https://doi.org/10.1007/s00289-021-03810-x
https://doi.org/10.3390/polym14061095
4. The result and discussion need comparisons with the latest research works.
5. The conclusion part must be written briefly and possible application of the developed composite can be explored and mentioned in the conclusion section.

Reviewer 3 Report
This is a good paper presenting a theroretical prediction of elastic modulus of UHMWPE fiber/PP composite. The most important issue is the variation of elastic modulus with the aspect ratio of UHMWPE fiber at a fixed filler content of 5%. The results are useful and encouraging. The paper can be considered for publication after some minor revisions.
1. In the introduction, it is better to mention the change of carbon fiber or glass fiber reinforced PP at different aspect ratios of the fiber applied.
2. Is there any similar work already reported previously for fiber reinforced polymer composite?
2. Higher aspect ratio of UHMWPE fiber results in higher elastic modulus of UHMWPE/PP composite, how about the effect of fiber diameter? Do the authors consider the effects of both diameter and length or only the aspect ratio of UHMWPE fiber?

Reviewer 4 Report
The manuscript: Analysis of Elastic Properties According to the Aspect Ratio of 2 UHMWPE Fibers Added to PP/UHMWPE Composites could be of interest to readers of the journal Applied Sciences. Paper. The paper includes current research issues and is scientific in nature. There are several inaccuracies in the article which need to be clarified before final publication.
- The results of the finite element method are interesting. Has the numerical model been verified in any way, e.g. experimentally? Such an approach would confirm the validity of the research.
- Equations 1-9 presented in the body of the article are not explained in the text. All symbols should be described in the text and the publication from which they are taken should be cited.
- Please explain where the physical properties shown in Table 1 are taken from.
- What does Poissonby mean in Table 1 or should it not be Poisson's ratio?
- The research methodology (numerical analysis) is not clearly presented in the paper.
- Suggests separating chapter 2 Materials and Methods into chapters Materials and Methods. And to expand the Methods chapter.
