Shattering Effect Study of Aramid–Steel Composite Target Plates under Localized Blast Loading
Round 1
Reviewer 1 Report
This paper studied to shattering effect study of aramid-steel composite target plates under localised blast loading. The article is, in general, well written but there are some issues that authors should consider to revise in order to improve its quality. Some comments were done in this way:
· The ithenticate similarity rate is 31 percent including references. This rate should be reduced below 25 percent, including references.
It can be accepted for publication with the approval of the editor after the similarity rate is reduced.

Reviewer 3 Report
The authors investigated the failure mode and damage mechanism of three kinds of ASCT plates with equal area density and single-layer steel plate under local explosion load.
The results show that the aramid laminates stuck on the back explosion surface ASCT (SA) exhibit the best anti-explosion effect, which is center deflection reduced by 12% and 18% compared with the single-layer steel plate (S-1) and the equal thickness steel plate (S-2), respectively, plate ASCT ( SA ) Plate ASCT ( AS ) and ASCT ( SAS ) plate center tear failure did not occur. The analysis shows that different combinations change the propagation of stress waves in the structure, which in turn affects the failure of the composite plate.
The critical failure dose of different structural configuration plates is obtained by simulation. The influence of explosion center distance, explosive charge and bonding thickness of aramid laminate on the central deflection of steel plate were discussed by dimensional analysis, and the empirical formula of central deflection of aramid-steel composite target plate was obtained. The research results can provide a theoretical basis and reference for the lightweight and efficient protection of composite structural armor.
The following conclusions can be drawn:
1. The structural configuration of the explosion-proof surface of the steel plate stuck aramid laminate can effectively improve anti-explosion performance.
2. The anti-explosion mechanism of ASCT (SA) plate was analyzed from the perspective of stress wave propagation and energy absorption.
3. The failure modes of ASCT (SA) plate under different TNT charge, explosive center distance and aramid laminate thickness were analyzed by experiment and numerical calculation, and the corresponding empirical formulas were given.
The paper should be carefully revised before acceptance.
The abstract should show significance of the proposed work.
Please highlight the motivation, novelty and contributions in introduction.
Nomenclature section should be added.
What are the limitations of the used method?
How the authors obtained correlation in Figure 22-24.
The introduction should be supported by recent publications of composite materials in different engineering fields:
Recent progresses in wood-plastic composites: Pre-processing treatments, manufacturing techniques, recyclability and eco-friendly assessment
Bistable Morphing Composites for Energy-Harvesting Applications
More discussion on the failure modes including (a) Elastic deformation, (b) Plastic large deformation, (c) Fiber fracture (d) Cap failure, should be added.
How did you obtain damage data tabulate din Table 8?
Add a section or a paragraph to suggest future prospects.
Looking and wishes for the revised version.
