Reinforced Structure Effect on Thermo-Oxidative Stability of Polymer-Matrix Composites: 2-D Plain Woven Composites and 2.5-D Angle-Interlock Woven Composites
Round 1
Reviewer 1 Report
GENERAL COMMENTS
# In this study the thermo-oxidative stability of carbon fiber polymer matrix composites with different integral reinforced structures was investigated experimentally and numerically. (Specimens of the 2-D plain and 2.5-D angular interlock fabric composites). The question is: Does thermal oxidative aging cause degradation of the matrix and the fiber/matrix interface?
# Interesting subject. Relevant research.
#The research methodology raises some doubts that I would like to see clarified:
-- Is the degradation because of temperature or because of oxidation (Because of the presence of oxygen)?
-- If the tests were performed for temperatures below the Tg of the resin would the behavior be the same?

-- How did you obtain this volume fraction? What is the procedure (or standard)?
-- What equipment did you use (make, model, location where it was used)?
-- Are these volume fraction or mass fraction values?
Table 1:
In: Table 1. Specifications of preforms.
Replace with: Table 1. Manufacturer Specifications: (name of manufacturer)
in: Table 1:
Clarify the parameter "density/(ends·cm-1)". For mass density values (mass divided by volume), use International Metric Units. Density ρ, [kg/m3]
4. Results and discussion
Page 11 and page 12:
Figures 13 and 14 must be quality improvements
Figure 15. For a better analysis of the graphs in Figure 15 the axes should have the same range (e.g. Y: 0-70; X: 0-1.2)
Page 13 :
In Figures 17, define: What are the failure modes of the AWC specimens?
What are the failure modes of AWC specimens? Use the same names: failure in tension and failure in delamination.
5. Conclusions
Page 14: The conclusions should be improved, particularly by quantifying the results obtained.
