用于轴流式涡轮机低压压缩机的复合壳体
摘要：
本发明涉及一种用于制造轴流式涡轮机低压压缩机的复合壳体的方法，该壳体包括圆形壁以及与壁形成锋利的拐角的固定凸缘。该方法包括以下步骤：提供(100)具有配置成形成壳体的边缘拐角的拐角的模具；将填充的热塑性树脂轮廓部分沿拐角放置(106)；将纤维加强件放置(107)在模具中以拥抱所述轮廓部分；将注射模具关闭(108)；将注射到模具中的树脂聚合(109)以及将壳体脱模(110)。本发明还涉及一种复合壳体，其具有环形壁以及在壳体的内侧形成锋利的拐角的壁的一个端部处的凸缘。壳体由纤维预成型件加强，并且边缘拐角以具有小于5.00mm平均长度的短纤维来加强。
摘要（英）：

The invention relates to a method for manufacturing a composite casing for an axial turbomachine low-pressure compressor. The casing comprises a circular wall and a fixing flange which with the wall forms a sharp-edged corner. The method comprises the steps of: supplying (100) a mould with a corner configured to form the edge corner of the casing; placing (106) a filled thermoplastic resin profile section along the corner; placing (107) a fibrous reinforcement in the mould to hug the profile section; closing (108) the injection mould; polymerizing (109) a resin injected into the mould and demoulding (110) the casing. The invention also relates to a composite casing with an annular wall and a flange at one end of the wall forming a sharp-edged corner on the inside of the casing. The casing is reinforced by a fibrous perform and the edge corner is reinforced with short fibers with a mean length of less than 5.00 mm.
