Point 1: This paper has been well prepared and can be accepted by the present form.

 Response 1: Thank very much for your kind and valuable comments to publish this research paper in “polymers”.

Reviewer 2 Report

The manuscript reports on a novel method to increase the compatibility of aramid fibrids with PU matrix. As a general comment, the authors addressed the issue in detail, presenting results coming from different experimental techniques. However there are some issues that should be addressed before the paper can be accepted for publication:

English language needs to be improved; Page 2 line 47: “The researcher defined…”, who? Page 3 line 100: “…under certain conditions”. The conditions should be specified; Page 4: the authors mention an increase in surface roughness after chlorination but from SEM micrographs provided it is difficult to be detected; Page 6 line 169: “sand MAFCs”. The meaning is not clear; Page 7 lines 198 and 200: some angles are wrong. What is the standard deviation of these measurements?; Figure 6b: It should be “kN…”; How many sample were mechanically tested? In table 4 standard deviations should be included. “Shao should be Shore”, and “kN instead of KN”; The etching procedure should be described; Figure 7: Higher magnifications should be provided to appreciate differences.

Round 2

Reviewer 2 Report

The authors have revised the manuscript but there are some issues that still need to be addressed as follows:

The standard deviations should be added in table 4 to check the dispersion of data; The quality of written English needs to be significantly revised and improved.
