Abstract
A composite laminate structure includes a cellular core and a first laminate layer coupled to the cellular core. The first laminate layer includes a first thermoplastic layer and a first fiber-reinforced polymer layer, where a first surface of the first fiber-reinforced polymer layer is thermally consolidated to a second surface of the first thermoplastic layer. A first surface of the first thermoplastic layer is directly in contact with and bound to a first surface of the cellular core by temperature reduction of the first thermoplastic layer below a glass transition temperature of the first thermoplastic layer while the cellular core is pressed against the first thermoplastic layer when the first thermoplastic layer is above the glass transition temperature of the first thermoplastic layer and the cellular core is below a temperature where materials of the cellular core flow or degrade.
