The invention discloses a three-dimensional woven composite material plate spring type undercarriage prefabricated body profiling forming tool and method. The three-dimensional woven composite material plate spring type undercarriage prefabricated body profiling forming tool comprises a tool frame, a core mold, five clamps and five connecting rollers. The three-dimensional woven composite material plate spring type undercarriage structure prefabricated body comprises nine areas including a first uniform cross-section area, a first variable cross-section area, a second uniform cross-section area, a second variable cross-section area, a third uniform cross-section area, a third variable cross-section area, a fourth uniform cross-section area, a fourth variable cross-section area and a fifth uniform cross-section area, vertical parts are arranged on the two sides of a plate spring, an arc part is arranged in the middle of the plate spring, and the plate spring is of a symmetrical structure. The thicknesses of the fabrics in different areas are different, variable-thickness integrated weaving is adopted in the weaving process, and the fabric areas comprise binding warp yarns and weft yarns. The defects that an existing undercarriage prefabricated body is woven in blocks and cannot be integrally formed can be overcome, better size control and good mechanical performance are achieved, the three-dimensional woven composite material is adopted, and the undercarriage prefabricated body has the advantages of being large in specific stiffness and high in specific strength and further has excellent layering resistance and impact resistance.
本发明公开了一种三维机织复合材料板簧式起落架预制体仿形成型工装及成型方法,包括工装架、芯模、五个夹具、五个连接棍,三维机织复合材料板簧式起落架结构预制体包括等截面区一、变截面区一、等截面区二、变截面区二、等截面区三、变截面区三、等截面区四、变截面区四、等截面区五九个区域,在板簧的两侧为竖直部分,中间为圆弧部分,呈对称结构,不同区域织物厚度不同,在织造过程中采用变厚度一体化编织,织物区包括接结经纱和纬纱。本发明能够解决现有起落架预制体分块织造、不能一体化成型的缺陷,实现更好的尺寸控制和良好的力学性能,采用三维机织复合材料,不仅具备比刚度大、比强度高的特点,还具备了优异的抗分层、抗冲击性能。
