线材及制备线材的方法
Abstract:
提供一种线材(10)。线材(10)沿纵向延伸方向(22)延伸，其中线材(10)具有围绕纵向延伸方向(22)布置的第一层结构(24)和围绕第一层结构(24)的第二层结构(32)，其中第一层结构(24)包含第一多层(26)，其中第一层结构(24)的各层(26)具有多根纤维(28)，其中第二层结构(32)包含第二多层(34)，其中第二层结构(32)的各层(34)具有多根纤维(36)，其中第一多层(26)的纤维(28)和第二多层(34)的纤维(36)各自在纵向延伸方向(30，38)上延伸，其中第一多层(26)的纤维(28)和第二多层(34)的纤维(36)的纵向延伸方向(30)各自相对于线材(10)的纵向延伸方向(22)以30°至60°且优选40°至50°大小的角度取向，其中第一多层(26)的纤维(28)相对于线材(10)的纵向延伸方向(22)以这样的方式延伸，使得在线材(10)的指定扭转载荷的存在下，所述纤维在其纵向延伸方向(30)上承受纵向压缩载荷，其中第二多层(34)的纤维(36)相对于线材(10)的纵向延伸方向(22)以这样的方式延伸，使得在线材(10)的给定扭转载荷的存在下，所述纤维在其纵向延伸方向(38)上承受纵向拉伸载荷，其中第一多层(26)的相邻层(26)的纤维(28)的纵向延伸方向(30)彼此相差0°至10°、优选2°至10°且更优选2°至6°大小的角度，其中第二多层(34)的相邻层(34)的纤维(36)的纵向延伸方向(38)彼此相差0°至10°、优选2°至10°且更优选2°至6°大小的角度。还提供一种用于制备线材(10)的方法。
Abstract(English):

What is proposed is a strand profile (10). The strand profile (10) extends in a direction of longitudinal extent (22), wherein the strand profile (10) has a first laminar structure (24) arranged around the direction of longitudinal extent (22) and a second laminar structure (32) surrounding the first laminar structure (24), the first laminar structure (24) comprises a first plurality of layers (26), each layer (26) of the first laminar structure (24) has multiple fibers (28), the second laminar structure (32) comprises a second plurality of layers (34), each layer (34) of the second laminar structure (32) has multiple fibers (36), the fibers (28) of the first plurality of layers (26) and the fibers (36) of the second plurality of layers (34) respectively extend in directions of longitudinal extent (30, 38), the directions of longitudinal extent (30) of the fibers (28) of the first plurality of layers (26) and of the fibers (36) of the second plurality of layers (34) are respectively oriented at an angle with a value in a range from 30 degrees to 60 degrees, and preferably in a range from 40 degrees to 50 degrees, relative to the direction of longitudinal extent (22) of the strand profile (10), the fibers (28) of the first plurality of layers (26) extend relative to the direction of longitudinal extent (22) of the strand profile (10) such that, in the case of design torsion loading of the strand profile (10), they are loaded in longitudinal compression in their directions of longitudinal extent (30), the fibers (36) of the second plurality of layers (34) extend relative to the direction of longitudinal extent (22) of the strand profile (10) such that, in the case of design torsion loading of the strand profile (10), they are loaded in longitudinal tension in their directions of longitudinal extent (38), the directions of longitudinal extent (30) of the fibers (28) of adjacent layers (26) of the first plurality of layers (26) differ from one another by an angle with avalue in a range from 0 degree to 10 degrees, preferably 2 degrees to 10 degrees and more preferably 2 degrees to 6 degrees, and the directions of longitudinal extent (38) of the fibers (36) of adjacent layers (34) of the second plurality of layers (34) differ from one another by an angle with a value in a range from 0 degree to 10 degrees, preferably 2 degrees to 10 degrees and more preferably 2degrees to 6 degrees. Also proposed is a method for producing a strand profile (10).
