Abstract

A method for manufacturing a composite material includes providing a matrix comprising a fiber material and a thermoset polymer. A length of the fiber tow is impregnated with the thermoset polymer via a Localized-In-Plane Thermal Assist (LITA) impregnation system. A dual curable polymer is provided between a first layer of the matrix and the second layer of the matrix, and the dual curable polymer includes a thermally curable component and a photocurable component curable by exposure to actinic radiation. The dual curable polymer is exposed to actinic radiation to at least partially cure the photocurable component. In this way, a layer of the composite material is formed, and the aforementioned steps are repeated until a desired number of layers have been stacked together to create a structure. The layer or the structure is heated to thermally cure the thermoset polymer and the thermally curable component of the dual curable polymer.
