Abstract

A fiber-reinforced composite material includes a bulk portion with a bulk matrix having reinforcing fibers embedded therein, and a surface portion with a plurality of laminated first layers serving as “expanding layers”, which expand and/or delaminate during fire impact. The surface portion also includes a plurality of laminated second layers different from the first layers and serving as “barrier layers”. The expanding layers and barrier layers can be arranged in an alternating sequence.

First claim

The invention claimed is:

1. A fiber-reinforced composite material, comprising:
a multilayer bulk portion forming a bulk of the fiber-reinforced composite material and comprising a plurality of fiber material layers embedded in a bulk matrix; and
a surface portion comprising a plurality of laminated first layers structurally configured to expand or delaminate during fire impact and a plurality of laminated second layers different from the plurality of laminated first layers, wherein the plurality of laminated first layers are arranged in an alternating sequence with the plurality of laminated second layers,
wherein at least one of the laminated first layers comprises a thermoplastic film, the thermoplastic being a polymer selected from a group consisting of Polyimide, Polyetherimide, Polyether sulfone, Polyamide, Polyamide-imide, Polysulfone, Polyphenylsulfone, Polyetherketone, Polyethylene terephthalate, Polyethylene, Polyester, Polyetherester, Polyesteramide, Polymethylmethacrylate, Polypropylene, Polystyrene, Polyvinylchloride or mixtures thereof.

2. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated first layers comprises fibers.

3. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated first layers comprises an intumescent modifier.

4. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated first layers has a thickness in a range of 5 to 300 μm.

5. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated first layers has a thickness in a range of 10 to 200 μm.

6. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated first layers has a thickness in a range of 20 to 130 μm.

7. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated first layers has a thickness of approximately 125 μm.

8. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated second layers comprises a surface matrix with embedded reinforcing fibers.

9. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated second layers comprises a polymer.

10. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated second layers comprises a resin matrix with inorganic particles dispersed in the resin matrix.

11. The fiber-reinforced composite material of claim 1 , wherein at least one of the plurality of laminated second layers comprises a resin matrix with organic particles dispersed in the resin matrix.

12. The fiber-reinforced composite material of claim 1 , wherein the plurality of laminated first layers are configured to expand or delaminate during fire impact above 100%.

13. A structural component, comprising:
a fiber-reinforced composite material, comprising
a multilayer bulk portion forming a bulk of the fiber-reinforced composite material and comprising a plurality of fiber material layers embedded in a bulk matrix; and
a surface portion comprising a plurality of laminated first layers structurally configured to expand or delaminate during fire impact and a plurality of laminated second layers different from the plurality of laminated first layers, wherein the plurality of laminated first layers are arranged in an alternating sequence with the plurality of laminated second layers,
wherein at least one of the laminated first layers comprises a thermoplastic film, the thermoplastic being a polymer selected from a group consisting of Polyimide, Polyetherimide, Polyether sulfone, Polyamide, Polyamide-imide, Polysulfone, Polyphenylsulfone, Polyetherketone, Polyethylene terephthalate, Polyethylene, Polyester, Polyetherester, Polyesteramide, Polymethylmethacrylate, Polypropylene, Polystyrene, Polyvinylchloride or mixtures thereof, and
wherein structural component is a component of an aerial vehicle.
