Embodiment Construction

[0008]Referring now to the drawing in detail, FIG. 1 illustrates a composite structure10 which is to be utilized for example on a Navy marine vessel. Such composite structure 10 includes a substrate 12 that is solid as shown, made of a structural material such as glass / vinyl ester preferred for shipboard use. A fire protective barrier layer 14 is attached to the substrate 12 by a suitable bonding adhesive 16, such as a phenolic or silicone adhesive.

[0009]With continued reference to FIG. 1, the barrier layer 14 includes a core 18 formed by an intumescent mat or felt, protectively covered by a water proofing skin 20 such as an aluminum foil. A fire resisting agent is introduced into such barrier 14 before its adhesive bonding attachment to the substrate 12. Such fire resisting agent is either phenolic resin or water, or an oil-based intumescent coating infused into the mat core 18.

[0010]As an alternative, the barrier layer 14 may be formed from other materials into which the fire resi...

Abstract

A composite structure having a substrate is protectively covered during fabrication by a barrier layer, such as an intumescent mat or felt, into which a fire resisting agent such as phenolic resin or water, or oil based intumescent coating is infused in-situ before attachment to the substrate and completion of composite structure fabrication. The barrier layer is infused in-situ with the phenolic resin before attachment by adhesive bonding to the substrate or infusion is performed during formation of the underlying substrate layer so as to achieve attachment without adhesive.

Description

[0001]The present invention relates generally to fabrication of composite structures in such a manner as to endow it with protective properties.BACKGROUND OF THE INVENTION[0002]Composite structures having a substrate made of a structural material such as glass / vinyl ester are presently utilized for shipboard use. Because of flammability concerns in regard to such structures, passive fire protection has been proposed involving attachment of insulation blankets by means of self tapping screws. Installation of such fire protection for composite structures is both labor intensive and costly, especially in Naval shipboard types of seawater environments. It is therefore an important object of the present invention to provide less costly and less labor intensive fire protection for the foregoing referred to types of composite structures.SUMMARY OF THE INVENTION[0003]In accordance with the present invention, during fabrication of a composite structure having a solid substrate made of a pref...
