Structure of PET Foam Sandwich Panels

The sandwich structure is the most common composite panel structure. PET foam can be combined with glass fiber, aluminum, steel, plywood and other materials to form sandwich panels for different purposes.

  • Skin: Fiberglass, Aluminum, Plywood, Pre-painted steel, Stainless steel
  • Core: PET Foam Board

Skin Series

PET foam is basically compatible with all skin material systems through glue, not limited to fiberglass, aluminum, steel, plywood, etc. Which material to choose as the skin material depends on your product requirements.

PET Foam Core

PET (Polyethylene terephthalate) foam is a closed-cell rigid foam. It has the characteristics of light weight, heat resistance, non-absorbent, high strength and easy shearing. It can replace wood as the filling core material, and it can be recycled, which is an environmentally friendly material recognized and promoted worldwide.

Fiberglass Skin PET Foam Sandwich Panels

Fiberglass foam sandwich panels are more and more favored by various industries, and fiberglass sheets are lightweight and strong. In addition to using the traditional thermosetting fiberglass sheet (FRP) as the skin, TOPOLO developed the thermoplastic CFRT (continuous fiberglass reinforced thermoplastic ) sheet, which is a new type of skin material, and the continuous fiberglass gives it better toughness, which reduces the impact force transmitted to the core material.

Advantages of Fiberglass PET Foam Sandwich Panels

  • Lightweight
  • Toughness
  • Waterproof
  • Heat insulation
  • Flat & smooth surface

The impact of ordinary strength will not cause damage to the structure of the fiberglass PET foam composite panel, and it can keep the surface smooth.


PET foam sandwich panels are widely used in vehicles, construction, high-speed rail, ships, furniture and other fields, especially fiberglass PET composite panels are lighter, stronger, longer life, and lower cost than traditional metal or wood material panels. This makes them widely used in RV and truck manufacturing such as walls, floors, partitions, roofs, etc.
