FAQ – Frequently Asked Questions

Q1: What is the difference between Kevlar Prepreg and dry aramid fabric?
A: Prepreg contains pre-impregnated resin with controlled resin content, offering higher mechanical consistency and better processing quality.

Q2: Can I request a custom resin content or weave pattern?
A: Yes. We provide full customization of weave, resin system, resin content, and width.

Q3: Is Kevlar Prepreg suitable for high-temperature molding?
A: Using BMI or cyanate ester resin systems, it can be used for higher-temperature aerospace applications.

Q4: How should I store the material?
A: Keep it below –10°C in sealed packaging to maintain B-stage condition.
