Self-Healing Structural Materials
Round 1
Reviewer 1 Report
The manuscript entitled "Self-Healing Structural Materials" presents a critical vision of the current state of the art of the technologies available for obtaining hard self-healing materials. The work also presents the latest advances in the three most important types of hard materials: fiber-reinforced plastic composites, cements and metallic materials. This perspective is very well written and easy to follow and understand. In addition, the references are very up-to-date, which gives an idea of the current relevance of this topic.
For all these reasons, I consider that the manuscript can be accepted in the present form.

Reviewer 2 Report
This manuscript must be considered as a review article. Therefore, this manuscript needs essential modifications as follows:
- "A review article" must be presented in the title of the manuscript.
- The English language should be improved throughout the manuscript. Please write the manuscript in reporting style or using passive sentences (not active sentences, e.g., we, I, etc.), see Abstract, Line # 13 " Herein, we discuss cutting-edge self-healing technologies for hard materials". This comment applies to the whole manuscript.
- Line # 13, "hard materials". Therefore, a review of self-healing in ceramic and ceramic composites should be included in this paper
- The Title of Sec. 2 should be improved to be "Self-Healing in Polymers and their composites". In addition, this section should be extended, and the following Refs. Should be added:
- Print ISBN: 9780128184509 eBook ISBN: 9780128184516
