Abstract
Methods and apparatus to increase fire resistance and fracture toughness of a composite structure are described. An example apparatus includes a composite structure formed by an innermost ply and a fire-resistant ply including a first additive to increase a flammability resistance of the structure, where the fire-resistant ply is an inner ply of the composite structure.
