Abstract
Composite materials and methods of manufacturing composite materials, such as for use in aerospace parts, are described herein. A representative method for manufacturing a coated composite material structure includes applying a plurality of material layers to a preform structure. The plurality of material layers can include at least one first material layer (including a first matrix precursor), and at least one second material layer (including a second matrix precursor and a coating precursor). The method can also include infusing the preform structure with the first and second matrix precursors and the coating precursor from the plurality of material layers. The method can further include heating the infused preform structure to concurrently form a composite material structure and a coating on at least a portion of the composite material structure.
