Abstract
A method for selective needling on a fibrous preform includes performing a through thickness reinforcement process on the fibrous preform and varying a needle density, a needle angle, and/or a needle penetrating depth during the through thickness reinforcement process such that a first needle density, a first needle angle, and/or a first needle penetrating depth of a first zone of the fibrous preform is greater than a second needle density, a second needle angle, and/or a second needle penetrating depth of a second zone of the fibrous preform. The method can further include identifying expected interlaminar stress throughout the fibrous preform and varying the needle density, needle angle, and/or needle penetrating depth in accordance with a magnitude of the expected interlaminar stress.
