Methods For Three-Dimensional Weaving Of Composite Preforms And Products With Varying Cross-Sectional Topology

摘要

Methods creating composite preforms with a three-dimensional weaving pattern include stacking material layers and then connecting them with interlayer reinforcements. First and second layers are aligned and separated by a first layer spacing. First interlayer reinforcements are then inserted through at least the first and the second layers. At least a third layer is aligned with at least the first and second layers. Second interlayer reinforcements are inserted through at least the second and third layers, using the first layer spacing between the first and second layers to manipulated the second interlayer reinforcements during insertion. Following the insertion of at least the second interlayer reinforcement, this layer spacing is closed to bring the first and second layers into contact. Further layers and interlayer reinforcements may be added, using additional layer spacings to manipulate additional interlayer reinforcements to form complex three-dimensionally woven composite preforms.

主权项

1. A method of producing a fiber composite preform, the method comprising:
aligning first and second material layers separated by a first layer spacing; inserting first interlayer reinforcements through the first and the second material layers; aligning at least a third material layer with at least the first and second material layers; inserting second interlayer reinforcements through at least the second and third material layers, wherein the first layer spacing enables the second interlayer reinforcements to be manipulated during insertion; and closing the first layer spacing to bring the first and second material layers into contact.
