先进的可变半径层压式复合材料半径填料
Abstract:
填料一种复合材料半径填料(200)包括基底部分(238)和尖端部分(220)。基底部分(238)由复合材料层片(258)形成，所述复合材料层片(258)沿整体长度方向(202)在整体宽度上改变并沿所述长度方向(202)限定所述基底部分(238)的可变横截面形状。所述基底部分(238)包括沿所述长度方向(202)具有过渡开端(296)和过渡末端(298)的至少一个过渡区(294)。所述基底部分(238)的复合材料层片(258)被布置在一个或更多个堆叠(250)中，每个堆叠具有预定纤维取向角(262)序列和在所述过渡区(294)内改变的堆叠宽度(278、282)。所述尖端部分(220)包括形成为大致三角横截面形状并堆叠在所述基底部分(238)的顶部上的多个复合材料层片(258)。
Abstract(English):

A composite radius filler (200) include a base portion (238) and a tip portion (220). The base portion (238) is formed of composite plies (258) varying in overall width along an overall lengthwise direction (202) and defining a variable cross-sectional shape of the base portion (238) along the lengthwise direction (202). The base portion (238) includes at least one transition zone (294) having a transition start (296) and a transition end (298) along the lengthwise direction (202). The composite plies (258) of the base portion (238) are arranged in one or more stacks (250) each stack having apredetermined fiber orientation angle (262) sequence and a stack width (278, 282) that changes within the transition zone (294). The tip portion (220) includes a plurality of composite plies (258) formed into a generally triangular cross-sectional shape and stacked on top of the base portion (238).
