Embodiment Construction

[0039] Below by specific embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0040] Such as figure 1 and figure 2 Shown: a method for designing and manufacturing a composite material blade. The composite material blade is composed of a composite material and a metal skeleton. Composite blades in a sandwich structure. Using the composite material of the preformed sheet to manufacture the composite material blade can simplify the manufacturing process and reduce the cost.

[0041] The composite material blade is divided into a working surface and a non-working surface. The side on which the composite material blade is subject to greater fluid pressure is the working surface, and the side on which the fluid pressure is less is the non-working surface. The working surface and the non-working surface The ply thickness is designed for a smooth transition to avoid a faulty structure between the metal skeleton and the composi...

Abstract

The invention provides a method for designing and manufacturing a composite material blade, in which preformed sheets are laid on two metal skeletons, and a composite material blade with a sandwich structure is formed after curing and compounding by a curing device. The composite material blade manufactured by using the preformed sheet can simplify the manufacturing process, reduce the cost, and has good integrity and bonding strength. The present invention also relates to a composite material blade, comprising a composite material and a metal skeleton, the metal skeleton is prefabricated into a blade shape, and a preformed sheet made of multi-layer prepreg fiber cloth is laid on the outside of the metal skeleton. The metal skeleton is provided with a through hole, and the carbon fiber wire harness that fixes the metal skeleton and the preformed sheets on both sides is wound in the through hole, and is solidified into a composite material blade by a curing device. The composite material blade of the present invention has the advantages of no twisting, twisting, or breaking under extreme working conditions, good weather resistance, certain impact resistance, and can meet the special requirements of aviation and ships.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a design and manufacture method for a composite material blade and the composite material blade. Background technique [0002] Existing composite material power blades are generally combined, and the blades and hubs are prepared separately, and then assembled into one body by mortise joints or plug joints. The pure composite material is connected with the metal or composite material hub, and there is assembly stress, while the pure composite material is easy to fail from the stress concentration point, which affects the fatigue life of the composite material blade; the metal and composite material composite molding blade, experiences cold and heat cycles during work Finally, there are risks of delamination and debonding between the metal and the composite material, and even the separation of the composite material and the metal. [0003] No patent literature report on the same...
