METHOD AND APPARATUS FOR ENHANCING FIRE RESISTANCE AND FRACTURE TOUGHNESS OF COMPOSITE STRUCTURE

摘要

To provide a composite structure having enhanced fire resistance while maintaining fracture toughness without influencing manufacturing flow or weight.SOLUTION: Disclosed herein is a method and an apparatus for enhancing fire resistance and fracture toughness of a composite structure. An example apparatus includes a composite structure formed by an innermost ply and a fire-resistant ply including a first additive for enhancing flame resistance of the structure, where the fire-resistant ply is an inner ply of the composite structure.SELECTED DRAWING: Figure 1A
