FRP PET Sandwich Composite Panel

2.0 mm FRP (RAL 9003) + 6 mm PET Core + 1.5 mm Woven Roving FRP (RAL 9003)

FRP PET Sandwich Composite Panel is manufactured by bonding FRP skins to a PET core using structural adhesives and specialized pressing equipment. The result is a lightweight yet heavy-duty panel with excellent rigidity, impact resistance, and moisture-proof durability—ideal for RV roof, floor, and interior wall applications, as well as commercial vehicle interior linings.

Why Choose This Panel

◊Built for RV duty: excellent impact resistance for roofs, floors, and interior panels

◊Rigid & lightweight: PET core provides high stiffness with low weight for better vehicle efficiency

◊Moisture & rot proof: composite structure is waterproof and will not rot like wood-based panels

◊Durable surface：RAL 9003 FRP surface is smooth, easy to clean, and resists staining and aging

◊Stable structure: woven roving backing enhances dimensional stability and reduces warping/de-lamination risk

Typical Applications

◊RVs & Caravans: roof panels, floor panels, interior wall/ceiling panels, cabinetry & furniture surfaces

◊Commercial Transport: Truck/trailer interior linings, box body panels, bus interior panels

◊Specialty Use:marine interiors, mobile workshop interiors, lightweight partition systems

Technical Specifications

Product Description

This composite panel consists of three functional layers:

◊ 2.0 mm FRP face (RAL 9003) as the durable, easy-clean surface layer

+ ◊ 6 mm PET core as the lightweight, rigid core material providing stiffness and insulation benefits

+ ◊ 1.5 mm woven roving FRP back (RAL 9003) to enhance impact resistance and structural integrity

Produced through controlled bonding and curing, the panel ensures reliable integration between layers and serves as a high-performance alternative to wood-based panels in RV roofs, floors, walls, and commercial vehicle interiors.
