The present invention provides a composite laminate for a fuselage lifting surface made of a prepreg material and comprising at least two sides and a ramp region defined by reduced staggered laminates extending in a ramp direction, comprising: a first ply formed of strips arranged parallel to the ramp direction, a second sheet layer formed of a tape arranged orthogonal to the slope direction, a third sheet layer formed of a tape arranged in a first laying direction, the first laying direction being different from the slope direction and a direction orthogonal to the slope direction, and a fourth sheet layer formed of a tape arranged in a second laying direction, the second laying direction differs from the ramp direction, a direction orthogonal to the ramp direction and the first laying direction, in which in the ramp region the strip forming the third and/or fourth plies extends from one laminate side to the other. The invention also provides a fuselage lifting surface comprising the composite laminate and a method for manufacturing the composite laminate.
本发明提供一种用于机身升力面的复合层压件,其由预浸材料制成,并且包括至少两个侧边以及由沿着斜面方向延伸的减少的交错层压件限定的一个斜面区域,其包括:由平行于斜面方向布置的带形成的第一片层,由正交于斜面方向布置的带形成的第二片层,由在第一铺设方向上布置的带形成的第三片层,第一铺设方向与斜面方向以及与斜面方向正交的方向不同,以及由在第二铺设方向上布置的带形成的第四片层,第二铺设方向与斜面方向、与斜面方向正交的方向以及第一铺设方向不同,其中,在斜面区域中,形成第三片层和/或第四片层的带从一个层压件侧边延伸到另一个层压件侧边。本发明还提供一种包括该复合层压件的机身升力面以及用于制造该复合层压件的方法。
