摘要：
Provided are composite feedstock strips for additive manufacturing and methods of forming such strips. A composite feedstock strip may include continuous unidirectional fibers extending parallel to each other and to the principal axis of the strip. This fiber continuity yields superior mechanical properties, such as the tensile strength along strip's principal axis. Composite feedstock strips may be fabricated by slitting a composite laminate in a direction parallel to the fibers. In some embodiments, the cross-sectional shape of the slit strips may be changed by reattributing material at least on the surface of the strips and/or by coating the slit strips with another material. This cross-sectional shape change may be performed without disturbing the continuous fibers within the strips. The cross-sectional distribution of fibers within the strips may be uneven with higher concentration of fibers near the principal axis of the strips, for example, to assist with additive manufacturing.
摘要（中）：
提供的是用于添加制造复合原料条和形成搜索条的方法。 复合给料条可以包括连续的单向纤维彼此平行和以条带的主轴线延伸。 这种纤维的连续性产生优异的机械性能，：如沿着条的主轴线的拉伸强度。 复合给料带可以通过在平行于纤维的方向上切割的复合层压材料来制造。 在一些实施例中，切割带的横截面形状可以至少由条带和/或通过与另一种材料涂覆所述切割带的表面上reattributing材料而改变。 此横截面形状可以变化，而不会干扰带内连续纤维来执行。 条带内的纤维的横截面的分布可以是不均匀的与所述条带的主轴线，例如靠近纤维的浓度较高时，以辅助的添加剂制造。
