Comparative example
Comparative example 1

Comparative example 2
A composite material fan blade, which is different from embodiment 1 in that the quality of HYVER resin and the like in the above steps is replaced by polyurethane resin (PU).
Performance testing test samples: the composite fan blades obtained in examples 1 to 10 were used as test samples 1 to 10, and the composite fan blades obtained in comparative examples 1 to 2 were used as control samples 1 to 2.
The evaluation method comprises the following steps: based on the total man-hour of the manufacturing process of the blade and the material cost (including the main resin, the fiber material, the PVC foam core material, the balsa core material, and the epoxy structural adhesive), a cost structure analysis is performed, and compared with the conventional process (comparison sample 1) of manufacturing the blade with the main material epoxy resin (epoxy), the comparison result includes the reduction of cost and the improvement of production efficiency, and the analysis result is shown in table 2.
And (3) test results:
TABLE 2 test results of test samples 1-10 and control samples 1-2
Combining example 1 and comparative examples 1-2 with table 2, it can be seen that the use of HYVER resin instead of mainstream resin can effectively reduce costs. The viscosity of the epoxy resin (epoxy) is higher than that of the HYVER resin and the reactivity is lower, so that the laminated structure is fully wetted and impregnated by the epoxy resin (epoxy), and the filling time is prolonged by 10-30% compared with that of the HYVER resin; and the time for heating and curing the later stage is prolonged by 10-30% compared with that of HYVER. The polyurethane resin (PU) has high actual resin cost, and the polyurethane resin raw materials are greatly influenced by moisture, so that all fiber raw materials and core materials cannot use the conventional products sold in the market and need to be produced in a customized manner, so that the PU is a great problem in batch application and production cost; the HYVER resin material has excellent water resistance and is not easily affected by water, so that most of fiber raw materials and core materials with the existing specification can be directly selected, and the material cost is increased by more than 30% by using polyurethane resin (PU).
Combining example 1 with examples 2-5, 7-10 and table 2, it can be seen that the cost reduction comes primarily from the replacement of the primary resin, with limited cost impact from adjusting for the secondary materials.
As can be seen from the combination of the embodiment 1 and the embodiment 6 and the table 2, even though the carbon fiber can improve the product characteristics, the cost structure shows that the glass fiber has the advantages of low cost, complete specification, stable supply and the like, so the composite material fan blade preferably uses the glass fiber except for using the carbon fiber as the fiber reinforcing material in the special specification.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
