The invention relates to a method for producing a structural component (1, 1 ', 1' ', 1 ''', 1'' '') made of a composite material, comprising a skin (2) and at least one stiffening stringer (3, 3 ', 3' ', 3''', 3 '''') rigidly and integrally applied to a face (2a) of the skin (2); the method comprises the following steps: a) arranging on the tool (12, 12 ', 12' ', 12' '') a plurality of first layers (4; 4 ', 4' ') of uncured or pre-cured composite material forming the stringer (3, 3', 3'', 3 ''', 3'' ''); 4a ', 4b'; 4 ''; 4 '''; 4a '''', 4b '''', 4c ''''), the stringer (3, 3 ', 3 '', 3''', 3 '''') having a longitudinal axis (A) and having a raised portion (7, 7 ', 7 '', 7''', 7 '''') protruding from at least one flange (8), the flange (8) extending parallel to the longitudinal axis (A) and along a mat surface, the mat surface being a plane or a surface of revolution (S); b) arranging on the tool (12, 12 ', 12' ', 12 ''') a plurality of second layers of uncured or pre-cured composite material forming the skin (2); c) the face (2a) of the skin (2) is parallel to the underlying face (S) and the flanges (8) of the stringers (3, 3 ', 3 ", 3"', 3 "") are bonded to each other; d) applying a predetermined temperature and pressure on the assembly so formed so as to press the layers together, capable of curing the uncured material and rigidly bonding the skin (2) to the stringer (3, 3 ', 3' ', 3' '', 3'' ''); and e) performing a cutting operation on the free end side edge (13) of the flange (8) in a direction transverse to the pad surface (S); and f) covering the end-side edge (13) of the flange (8) with a composite coating in order to externally seal the layer (4; 4a ', 4b'; 4 '', 4'' ', 4a '''', 4b '''').
一种用于制造由复合材料制成的结构部件(1、1'、1”、1”'、1””)的方法,该结构部件包括蒙皮(2)和至少一个刚性地且一体地施加到蒙皮(2)的一个面(2a)的加强桁条(3、3'、3”、3”'、3””);该方法包括以下步骤:a)在工具(12、12'、12”、12””)上布置形成桁条(3、3'、3”、3”'、3””)的多个未固化或预固化复合材料的第一层(4;4a'、4b';4”;4”';4a””、4b””、4c””),桁条(3、3'、3”、3”'、3””)具有纵向轴线(A)并具有从至少一个凸缘(8)突出的凸起部分(7、7'、7”、7”'、7””),凸缘(8)平行于纵向轴线(A)并沿着垫面延伸,垫面是平面或者是回转面(S);b)在所述工具(12、12'、12”、12””)上布置形成所述蒙皮(2)的多个未固化或预固化复合材料的第二层;c)使所述蒙皮(2)的面(2a)平行于所述垫面(S),并且使所述桁条(3、3'、3”、3”'、3””)的所述凸缘(8)互相粘合;d)在这样形成的组件上施加预定的温度和压力,以便将各层压紧在一起,能够固化未固化的材料,并将所述蒙皮(2)刚性地结合到所述桁条(3、3'、3”、3”'、3””);以及e)沿着相对于垫面(S)横向的方向在所述凸缘(8)的自由端侧边缘(13)上执行切割操作;以及f)用复合材料涂层覆盖所述凸缘(8)的所述端侧边缘(13),以便从外部密封形成所述凸缘(8)的层(4;4a'、4b';4”;4”';4a””、4b””)。
