Abstract

The invention discloses a composite material tube forming tool system, and belongs to the field of unmanned aerial vehicle composite tubes. The composite material tube forming tool system is mainly used for solving the problem that the composite material tube with the characteristics of complex working conditions, complex paving layers, a conical structure, a large size (the length exceeding 6m) and the like is high in manufacturing difficulty. The forming tool system mainly comprises an upper die body, a lower die body, a cover plate and an auxiliary paving tool, wherein the upper die body and the lower die body are both of a female die structure, and a frame welding structure is adopted; the cover plate is of a flat plate structure, and a putty strip pasting area and connecting bolt holes are designed in the cover plate; the auxiliary paving tool is of an L-shaped structure and connected to the upper die body and the lower die body through positioning pins and bolts, and the auxiliary paving tool is equipped with a paving identification line used for identifying layer loss and paving of prepregs. The forming tool system is particularly suitable for manufacturing conical and large-size (the length exceeding 6 m) carbon fiber composite tubes.

Description

technical field [0001] The invention relates to a molding tooling system for composite material pipes, which belongs to the field of UAV composite material pipes, and is mainly used for composite material pipes with complex working conditions, complex layering, conical structure, and large size (more than 6m). Create difficult problems. Background technique [0002] Carbon fiber is an ideal material for structural design due to its excellent properties of low density, high specific strength and high specific modulus; figure 1 As shown, the carbon fiber composite material tube is a typical structure in the product structure design, and is often used in the wing spar, tail support tube, empennage main beam, rudder surface main beam and other important structural areas of UAVs. Carbon fiber is a special material whose tensile properties are far greater than compressive properties. In the manufacturing process of carbon fiber composite products, it is necessary to avoid problem...
