摘要：
A composite part is manufactured by an additive process, which includes locating a layer of fibers, selectively depositing a matrix material in a predetermined pattern onto portions of the layer of fibers to form a matrix material layer, repeating these steps to generate a preform of the composite part, and applying heat and pressure to the preform to consolidate the layers of fiber and the layers of matrix material. During the depositing of the matrix material, voids are created within at least one layer of the matrix material by intentionally not depositing matrix material over predetermined areas of the layer of fibers, the predetermined areas configured to be within an outer boundary of the predetermined pattern of the matrix material.
