Analysis of Ballistic Impact of 7.62 mm FMJ M80 Rifle Projectile into Twaron/UHMWPE Composite Armor

Round 1

Reviewer 1 Report

Major issues

·        The paper is interesting, but it must underline more the novel character of the study or it elements. Namely, what was is unique here? Armor composition, manufacturing methodology or/and something else?

·        Comparison or at least description of other composite armor solutions could be presented.

·        More explanation in reference to the previous papers of the team (cited as 39 and 40 in the manuscript) should be stated.

Minor issues

·       UHMWPE abbreviation should be explained before first use
·       Line 282-283, the area is presented in mm units? Probably it is the diameter of the hole?

Reviewer 2 Report

The authors performed paper conducted some interesting tests on fibre composite for use as armour material. They conducted hardness tests and impact tests, describing the results in quite a bit of detail. The preparation method of the laminates is also described very well.

I think the paper is worthy of publication, subject to some minor comments:

- In table 1, is the “Tensile strength module” the Young’s modulus of the fibres?

- In general, the paper would benefit from another proof reading to correct small English issues. However, it is understandable throughout already.

- the authors stated the distance to the target was 25 m. However, it seems to be 22.5 m in figure 10. Which is correct?

- Would it be possible to provide the thickness in mm of the layers shown in figure 13?

The English is quite clear, however there are small imprecisions. A further round of proof reading should be sufficient at this stage.

Round 2

Reviewer 1 Report

The authors responded to all the points of my review, however, I still feel the lack of description, which is a fundamental novelty of this research study. I mean one specific statement that will highlight the innovative nature of this work. I leave the decision of what to do with this fact to the Editors.
