New Trends in Glass Fiber Reinforced Composite Panels
The CFRT skin XPS foam sandwich panel is a new thermal insulation composite panel developed by TOPOLOGROUP for vehicle bodies. It consists of two layers of CFRT (continuous fiber reinforced thermoplastic) sheets, an XPS foam core, and several frame materials. As an alternative to thermosetting FRP/GRP foam core sandwich panels, it offers equivalent functionality and, in some cases, surpasses them.
Using thermoplastic CFRT instead of thermosetting FRP as the surface layer of the XPS foam sandwich panel can bring many benefits.

CFRT Sheet
Continuous fibers are combined with thermoplastic resins to create durable, lightweight and durable UD prepreg tapes, which are then thermal laminated together at set angles to form CFRT sheets with improved performance. CFRT laminates are known for their excellent mechanical properties, including high strength-to-weight ratio, good impact resistance, and resistance to environmental factors such as moisture and chemicals.
XPS Foam
XPS foam is a lightweight closed-cell foam with excellent performance in thermal insulation, mechanical strength, waterproofness and other aspects. It is one of the ideal choices for manufacturing high-performance composite panels.
About CFRT surface treatment
- Features: The surface of CFRT is covered with a polymer protective film, which makes its surface smooth and flat, achieving a glossy effect comparable to gel-coated FRP or metal panels.
- Features: There is no coating on the surface of CFRT, showing the polypropylene resin itself, and the surface is relatively rough.
How to Enhance the Strength of CFRT Skin Foam Sandwich Panels
Although CFRT sheets possess excellent mechanical strength, to compensate for the inherent limitations of the XPS foam core and improve the panel’s resistance to deformation, a common practice is to embed a “skeleton” material (such as wood, composite materials, or metal) within the panel to provide structural support, thereby meeting the manufacturing requirements for larger, higher-strength panels.
Common Applications
CFRT skin XPS foam sandwich panels are used to build insulated box bodies to provide continuous and stable thermal insulation and safety protection.
Cargo vehicle bodies
