Embodiment 1
[0036] Embodiment 1: A method for manufacturing a Z-pin reinforced composite wind turbine blade structure of the present invention, the method includes the following steps:
[0037] Step 1: Prepare high-performance Z-pin5 through advanced pultrusion equipment, design Z-pin5 parameters, and then implant Z-pin5 into foam preform 6;
[0038]Step 2: Lay the main girder 3 of the composite material on the special mold according to the designed laying sequence and the number of layers;
[0039] Step 3: Lay the upper half blade shell 1 in the upper mold of the wind power blade, lay the lower half blade shell 2 in the lower mold of the wind power blade, and then place the above-mentioned main girder 3 on the lower half blade The predetermined position of the casing 2 is such that the lower surface of the lower edge of the main beam 3 is in close contact with the inner wall of the lower half-blade casing 2, thereby forming a lower joint surface;
[0040] Step 4: Bending the above-menti...
Embodiment 2
[0050] A Z-pin reinforced composite material wind power blade structure of the present invention includes an upper half blade shell 1 and a lower half blade shell 2 that cooperate to form a blade cavity and are located in the blade cavity for bearing most of the wind power blade. The I-shaped main beam 3 of the bending load, the upper edge of the I-shaped main beam 3 is closely attached to the inner wall of the upper half blade shell 1 to form an upper joint surface, and the lower edge of the I-shaped main beam 3 and the lower The inner walls of the half-blade shell 2 are tightly matched to form a lower joint surface, and the joints of the upper joint surface and the joint of the lower joint surface are implanted with pinning bridges to improve the main beam 1 and the upper half-blade shell. 1 and the Z-pin5 of the connection strength between the I-shaped main beam 3 and the lower half of the blade shell 2, the blade cavity is filled with fillers on both sides of the I-shaped m...
