Hybrid Prepreg-Based Components Manufacturer for High-End Electric Vehicles

Setting New Standards in Lightweighting & Performance

At Rockman Advanced Composites, we are at the forefront of the composites revolution, pioneering the design and manufacture of hybrid prepreg-based components for high-end electric vehicles (EVs). As a trusted hybrid prepreg-based components manufacturer, our cutting-edge technologies are transforming the landscape of sustainable mobility and helping top-tier OEMs deliver unmatched performance, efficiency, and aesthetics.

What Is Hybrid Prepreg-Based Components?

Hybrid prepreg-based components are advanced composite materials made by combining different types of fibers—typically carbon fiber, glass fiber, or aramid fiber—with high-performance resin systems. These materials are pre-impregnated with resin (hence “prepreg”) and cured under controlled conditions to form lightweight yet ultra-strong structures.

Hybrid prepregs are engineered to offer:

• Optimized stiffness-to-weight ratio
• Excellent heat resistance
• Vibration damping
• Superior dimensional stability
• Design flexibility

By leveraging a hybrid approach, manufacturers can tailor properties for specific performance goals in electric vehicles—be it structural integrity, crash resistance, or thermal protection.

Why Hybrid Prepregs Matter in Electric Vehicles

The global shift to electric mobility demands a paradigm shift in material science. At Rockman Advanced Composites, we recognize that hybrid prepreg-based components are not just about light-weighting; they’re about redefining the fundamentals of EV design and performance.

Key benefits for high-end EVs:

1. Weight Reduction

Reducing vehicle weight directly enhances range, performance, and energy efficiency. Hybrid prepreg-based parts are up to 50% lighter than their metal counterparts.

2. Superior Mechanical Properties

They exhibit high tensile strength, impact resistance, and fatigue life, making them ideal for structural applications and safety-critical components.

3. Enhanced Thermal Management

Electric vehicles generate significant heat from battery packs and motors. Hybrid prepregs with glass and carbon fiber combinations ensure optimal thermal protection and stability.

4. EMI Shielding & Insulation

Our advanced formulations offer electromagnetic interference (EMI) shielding, crucial for EV electronics, and can be customized for electrical insulation as needed.

5. Aesthetic Design Flexibility

From glossy carbon fiber finishes to customized contours, hybrid prepreg-based parts enable creative freedom in exterior and interior styling.
