摘要： A method of forming a fabric preform for a composite component from a fabric having a plurality of hoop tows is disclosed. One end of the fabric is received on the form such that the hoop tows of the fabric extend in a direction generally perpendicular to a central axis of the form. The fabric is wrapped around the form and at least some of the hoop tows are separated into hoop tow segments while the fabric is under a tension to enable a space to develop between ends of adjacent hoop tow segments along the length of the hoop tow. This separation of adjacent hoop tow segments accommodates increased deformation of the fabric during formation of the fabric preform while still maintaining a presence of hoop tow segments in at least portions of the fabric.
摘要翻译： 公开了一种从具有多个环绕丝束的织物形成用于复合部件的织物预制件的方法。 织物的一端被接收在形式上，使得织物的环状丝束在大致垂直于形状的中心轴线的方向上延伸。 织物围绕该形状包裹，并且至少一些环状丝束分离成环状拖链部分，同时织物处于张力下，以使得沿着环形丝束长度的相邻箍部分的端部之间形成空间。 相邻的箍丝束段的这种分离在织物预成型件的形成期间适应织物增加的变形，同时仍保持在织物的至少部分中的箍牵引段的存在。

摘要： A fan spacer for placement between a pair of adjacent blades in a fan assembly and a related method of making. The fan spacer has a spacer body including an airflow surface shaped to direct air between the pair of adjacent blades in which the airflow surface is shaped on opposing sides to correspond to the pair of adjacent blades. An over molded feature is molded onto the airflow surface of the spacer body in which the over molded feature both includes an erosion coating on the airflow surface and, on the two opposing sides, seals configured to seal against the pair of adjacent blades on the opposing sides of the airflow surface.
