Reviewer 1 Report
Dear Authors, I have read your manuscript and some questions raised. Attached please find my notes. Overall. Interesting review about nanoengineered polymer composites. Introduction: Authors stated that "The fibre diameters may range from a few millimeters to sub nanometric ranges". Please add a reference for this statement. Introduction. Authors stated that " These fibre reinforced composites finds innumerous applications owing to their superiority in various properties". Authors could be more detailed. Authors could stress the concept of the advantages of fiber reinforced composites over unreinforced ones. Therefore, when introducing FRCs, Authors could add that " fiber reinforced composites FRCs are axial particulates embedded in fitting matrices. The advantages of FRCs over unreinforced ones are well known and their characteristics are useful for many scopes. The fields with a constantly increasing number of studies about FRC applications are Construction Science (Long-Term Flexural Behaviors of GFRP Reinforced Concrete Beams Exposed to Accelerated Aging Exposure Conditions. Yeonho Park, Young Hoon Kim , and Swoo-Heon Lee. Polymers 2014, 6(6), 1773-1793;) Aerospace (Fibre reinforced composites in aircraft construction. Soutis C. Progress in Aerospace Sciences Volume 41, Issue 2, February 2005, Pages 143-151), orthopedics (Use of carbon-fiber-reinforced composite implants in orthopedic surgery. Hak DJ, Mauffrey C, Seligson D, Lindeque B. Orthopedics. 2014 Dec;37(12):825-30.) and Dentistry (Fiber-Reinforced Composites for Dental Applications. Scribante A, Vallittu PK, Özcan M. Biomed Res Int. 2018 Nov 1;2018:4734986.).” These considerations could be added in Introduction Section. Introduction: Authors stated that " The dynamic response of these materials under various loading conditions were studied to check their suitability for certain applications". Please add a reference for this statement. 1.1Impact on Composites. Authors stated that “The impact studies on composites laminates have always been an area of concern for various researchers globally". In fact, Authors refer to various studies but in the initial part of the section there are only 2 references (3 and 4). Please add some references to sustain this statement. For example, when saying “In general, there are five types of velocity considered for the studying of impact responses: low velocity, sub ordnance, ordnance, ultra-ordnance, and hypervelocity” it could be useful to have a reference for each different velocity. 1.2State-Of-The-Art in Composite Impact Research. Authors stated that "The dynamic response of these materials under various loading conditions were studied to check their suitability for certain applications". Please add databases used (Scopus, WoS…). It is very important to define on which database the research has been conducted. 2.1Electrospun Nanofiber Mats. Authors stated that " Electrospinning is one of the most commonly used methods to produce nanofibres ranging from several micro meters to sub nanometric ranges". Please add a reference for this statement. Graphs. All the graphs are under permissions of Authors reported in references 66 (Balaganesan, G.; Velmurugan)67 (Balaganesan, G.; Velmurugan, R.; Kanny, K), 68 (Balaganesan, G.; Velmurugan, R.; Srinivasan, M.; Gupta, N.; Kanny, K), , 69 (Velmurugan, R.; Balaganesan, G.), 76 (Neisiany, R.E.; Lee, J.K.Y.; Khorasani, S.N.; Ramakrishna, S.), 77 (Esmaeely Neisiany, R.; Lee, J.K.Y.; Nouri Khorasani, S.; Bagheri, R.; Ramakrishna, S). All these graphs are from the same two research groups. If it is possible, in my opinion it would be better to report also data from other research groups. 3.

It has been stated that “The authors have conducted experiments for various initial velocities of projectile and have obtained residual velocities for each case of initial velocity”. Please add also other Literature 3. Nanofiller Reinforced Polymer Matrix Composites. The chapter 3 (6 pages) is unbalanced with the other three chapters 1, 2 and 4 (1, 2 and 3 pages respectively) that are much shorter. In my opinion, it would be better to add some discussion in other sections or reduce section 3. Photographs: ok Tables: ok References: some literature seems to be not indexed in Scopus.

Reviewer 2 Report
Dear Authors,
The manuscript is a good effort at summarizing he various researches and findings mainly in the field of the laminated polymer matrix composites. However, it seems authors have mainly summarized the key finding from various publications in the field by various authors, but no effort is made to pull together a comprehensive and clear story, to bring all of it together. This needs to rectified in the revised manuscript.
Additionally,
1) There are numerous acronyms throughout the manuscript not defined before 1st use such as DF, NF, FRF and various other polymer names.
2) Also, there are many typos and grammatical mistakes throughout the manuscript.
line 122-123 - font used is different
line 298 - the specimen without clay
line 380 - English grammer
line 402 - typo
3) Authors have used the term specimend throughout manuscript - never heard of it.
Thanks

The authors would like to appreciate the esteemed reviewer for the time and insightful comments provided. The manuscript has been thoroughly checked and corrected for grammatical mistakes and other language issues.
Reviewer 2 Report
Authors have addressed the concerns raised earlier in the revised manuscript. English language check is still required as some sentences are still grammatically incorrect and words are capitalized when they shouldn't.
example : page 1 - There has been researching, to further enhance.....
