Thermoplastic Honeycomb Panels

Thermoplastic honeycomb panels are fiberglass reinforced polypropylene honeycomb core composite panels. Its upper and lower facing sheets are multi-layer continuous fiberglass and polypropylene resin composites. The core material is polypropylene plastic with a honeycomb structure (We call this composite CFRT sheet). The core and face materials are laminated together after thermal bonding.

Facing – CFRT Sheets

CFRT (Continuous Glass Fiber Reinforced Thermoplastic) sheet is a new type of thermoplastic FRP material developed by TOPOLO. It is made of multiple layers of continuous fiberglass unidirectional tapes that are thermally fused together. The unidirectional prepreg tapes of each layer are interwoven in different directions (mostly at 0°, 90°). Due to the application of continuous glass fiber, CFRT sheet has very good strength and rigidity, so it does not need to be made very thick (mostly under 1mm) and still has good impact resistance, which is not available in ordinary thermosetting FRP sheets.

Core – Polypropylene Honeycomb

The honeycomb core of the thermoplastic honeycomb panel is a high-quality polypropylene material with a round hole design. Polypropylene is a thermoplastic synthetic resin with excellent performance, which has chemical resistance, heat resistance, electrical insulation, high strength, high wear resistance and other properties.

Features of Thermoplastic Honeycomb Panels

  • Lightweight

The density of the honeycomb structure material is relatively low, so the weight is very light.

  • High Strength

CFRT sheet can resist large physical stress impact. Therefore, the panel has good impact resistance, rigidity and flexibility.

  • Easy to Assemble

The assembly of thermoplastic honeycomb panels is very convenient. It can be assembled with screws, hollow rivets, adhesives or hot-melt welding.

  • Waterproof and Moisture-proof

This is the unique difference between fiberglass honeycomb panels and wooden boards. The material seals well, does not seep water, and does not absorb water even if the surface is damaged.

  • Corrosion Resistance

The composite panel is not easily corroded by grease, salt water and common chemicals.

Applications of Thermoplastic Honeycomb Panels

Due to the honeycomb structure, it has a high weight ratio. Honeycomb sandwich panels can effectively absorb energy when impacted. In various weight-sensitive applications, thermoplastic honeycomb panels are an effective means of reducing mass, which has positive implications for reducing production costs and environmental protection.
