复合材料部分带斜边斜坡

Composite material part with stringer on ramp
Abstract:
Composite material part (11) with stringer (31) on ramp, manufactured from a stack of fabrics, which comprises at least one zone (13) with two sectors (17, 19) having a greater thickness than that of the surrounding zones and with the stringer (31) situated on an edge (21) of said zone (13) in which: a) each group of fabrics (27, 27′ . . . ; 29, 29′, . . . ) of said sectors (17, 19) has the dimensions to form on said edge (21) a ramp with an acceptable gradient 1/p so that the stringer (31) remains situated on the ramp; b) the stacking of the zone (13) is carried out firstly by placing the fabrics (27, 27′, . . . ) of the first sector (17) and on these the fabrics (29, 29′, . . . ) of the second sector (19) in such a way that in the coinciding section (35) of said edge (21) the gradient of the resulting ramp is 1/(p/2).
Abstract(Chinese):

复合材料部件（11），其具有在斜面上的纵梁（31），由一叠织物制成，其包括具有两个扇区（17,19）的至少一个区域（13），该区域具有比周围区域的厚度更大的厚度， 位于所述区域（13）的边缘（21）上的纵梁（31），其中：a）所述区段（17）的每组织物（27,27'...，29,29'，...） ，19）具有在所述边缘（21）上形成具有可接受的梯度1 / p的斜面的尺寸，使得所述桁条（31）保持位于所述斜坡上; b）首先通过放置第一扇区（17）的织物（27,27'...）并且在这些织物（29,29'...）上进行区域（13）的堆叠， 第二扇区（19）的方式使得在所述边缘（21）的重合部分（35）中，所得到的斜坡的斜率为1 /（p / 2）。
