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.

FAQ 

1. What resin systems are used in aramid prepreg?

Common resin systems include:

• Epoxy resin (most widely used)

• High-toughness modified epoxy

• High-temperature resin systems (for advanced applications)

The resin system can be selected based on mechanical and thermal performance requirements.

2. What applications is prepreg aramid used for?

It is widely used in:

• Ballistic protection panels and armor systems

• Aerospace interior components

• Automotive safety structures

• High-impact resistant parts

• Sporting goods such as helmets and protective equipment

3. How is prepreg kevlar processed?

Prepreg aramid is typically processed using:

• Hot press molding

• Autoclave curing

• Vacuum-assisted forming (depending on application)

Final performance depends on curing temperature, pressure, and cycle time.

4. What storage conditions are required?

Prepreg aramid must be stored under controlled conditions:

• Refrigerated storage (commonly -10°C or below)

• Sealed packaging to prevent moisture absorption

• Limited room-temperature exposure before curing

5. Can prepreg aramid be customized?

Yes, customization is available for:

• Fiber type (aramid 1000D / 1500D / 3000D)

• Resin system and resin content

• Fabric weave structure

• Width, thickness, and roll length

• Application-specific performance requirements

6. Do you offer free samples?

Yes, we provide free samples for testing and evaluation. In most cases, customers only need to cover the shipping cost before bulk orders.
