Kevlar Prepreg is delivered in B-stage and is suitable for standard composite molding processes:
Vacuum bagging
Autoclave curing
Hot press molding
Compression molding
Temperature: 120°C – 180°C
Pressure: 0.5 – 0.7 MPa
Time: 60 – 120 minutes
(Exact parameters depend on resin system and product specification.)
Each batch of Kevlar Prepreg is inspected for:
Fiber orientation accuracy
Resin content uniformity
Surface quality
Mechanical performance
Width and weight consistency
Material certificates (TDS / COA) are available upon request.
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.
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.
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
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.
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
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
Yes, we provide free samples for testing and evaluation. In most cases, customers only need to cover the shipping cost before bulk orders.
