CFRT XPP Sandwich Panels

Amid the global pursuit of lightweighting and a circular economy, MPP (Microporous Polypropylene) foam core material is becoming a key alternative to traditional materials. With its core advantages of recyclability and lightweighting, it is revolutionizing technologies in truck trailers, RVs, composite panels, and other fields, offering a new solution for the transportation industry to break free from its reliance on plywood.

Differentiated Advantages of MPP Foam

  • Rigidity and Toughness: Existing foam materials are either hard and brittle, or soft and tough, and it is difficult to have both rigidity and toughness. The microporous polypropylene foam material has both rigidity and toughness, which complements the deficiency of the performance of the existing foam material.
  • Environmental Protection: The MPP foaming process is clean and pollution-free, and it can be recycled and reused. It is an environmentally friendly product.
  • High Temperature Resistance: The thermal deformation temperature of PP foam material is much higher than that of PS and PU foam materials.
  • Thermal Insulation: The micron-sized cells effectively reduce the convection of gas in the foam, thereby effectively reducing the heat transfer caused by air convection.
  • Lightweight: The density of MPP foam is generally below 50kg/cm³.
  • Waterproof: Micron-sized cells make its extremely low water absorption.

The sandwich panels were able to withstand repeated hammer blows, with slight dents on the surface but no cracks, and the overall structure was not affected.

Composite Process of CFRT MPP Sandwich Panels

Compared to composite panels that rely on adhesives, MPP foam is fused to the CFRT (Continuous Fiber Reinforced Thermoplastic Polypropylene) skin through a thermoplastic composite process, avoiding the delamination problem of the foam sandwich panel.

The heated lamination composite process offers high production efficiency, allowing the composited panels to be used immediately. This efficiency far exceeds the high-pressure vacuum forming of traditional FRP-skinned foam-core sandwich panels (which requires several hours of adhesive curing), significantly shortening production cycles.

Innovating the Transportation Market

The transportation industry’s demand for lightweight, durable, and cost-effective materials fully leverages the performance of MPP foam composite panels.

  • Weight Reduction: Reduces costs and increases efficiency, improving fuel or electricity efficiency and lowering transportation costs.
  • Durability: Effectively withstands the heavy loads, shocks, and vibrations experienced by trucks and trailers.
