Abstract
Hybrid fiberglass composite structures and methods for forming the same are disclosed. In one embodiment, a hybrid fiberglass composite structure includes a first laminate substrate and a second opposing laminate substrate. At least one of the first laminate substrate and the second laminate substrate includes at least one polymer fiber layer and at least one glass fiber layer. A cellular core structure is interposed between the first laminate substrate and the second laminate substrate and fixedly coupled to the first laminate substrate and the second laminate substrate.
