Precision-Engineered Composite Sandwich Structures

Structural Carbon-Rohacell Panels

Name: Structural Carbon-Rohacell Panels
Brand: Epic Fibers

We manufacture high-performance sandwich structures using prepreg carbon fiber and Rohacell (PMI) cores for maximum thermal stability and weight savings. Beyond flat panels, we produce complex 3D geometries using precision-machined cores to meet exact specifications. Our process delivers aerospace-grade quality in custom dimensions

Lightweight and heat resistant panels for every application

Benefits of Rohacell core

High-Temp Ready (180°C+)
Ultra-Low Resin Uptake
Superior Stiffness
RF & X-ray Transparent
Precision Machinability
Low TML and CVCM properties

The true advantage of Rohacell lies in its processing versatility. Its remarkable creep resistance and thermal stability allow for high-pressure autoclave consolidation at temperatures exceeding 180°C without losing dimensional accuracy. This makes it the premier choice for aerospace components, medical hardware requiring radiolucency, and RF-transparent radomes where signal interference must be eliminated. By integrating precision CNC-machining with our prepreg lamination, we deliver bespoke, mission-critical parts that outperform traditional sandwich structures in every measurable metric.

Delivering precision carbon sandwich panels and parts for global engineering sectors.

Applications of PMI Cored Structures

Motorsport & High-Performance Automotive

Our panels maintain full structural rigidity up to 180°C, preventing deformation and delamination in high-heat zones like diffusers, engine covers, and chassis components.

Advanced Medical Imaging

X-ray transparent, high-stiffness support systems for CT, MRI, and oncology. Delivers crystal-clear imaging with zero signal interference under heavy loads.

Aerospace Technology

Suitable for UAV airframes, control surfaces, and interior secondary structures. Provides extreme rigidity and fatigue resistance, enabling higher payload capacity and long-term dimensional stability under flight loads.
