A method for preparing basalt fiber mixed with rare earth elements for a drone

By performing mold operation surface layering, demolding cloth laying, closed system setting and baking curing treatment in the preparation method of basalt fiber mixed with rare earth elements for UAVs, combined with oven baking, stability determination and adhesive layer laying state determination, mixed rare earth adhesion state is generated. Mixed rare earth and adhesive layer solution slurry is prepared and adhesion treatment is carried out to complete the adhesive layer configuration and product structure laying. This solves the problem of unclear mixed rare earth introduction position and realizes the correspondence between the mixed rare earth adhesion surface and the basalt fiber reinforced plate.

AI Technical Summary

Technical Problem

In existing methods for preparing rare earth elements mixed with basalt fiber for UAVs, the location of the mixed rare earth introduction is unclear, the processing link between the basalt fiber reinforcement plate and the adhesive layer is unclear, and there is a lack of determination of the stable state and the adhesive layer laying state. This leads to an unclear correspondence between the mixed rare earth adhesion state and the adhesive layer, and an unclear relationship between the adhesion surface direction and the interlayer position during product structure laying.

Method used

By obtaining the mold operating surface, the following steps are performed: layering, release cloth laying, sealing system setup, and baking curing. Oven baking, stability determination, and adhesive layer laying status determination are conducted to generate mixed rare earth adhesion status. A solution slurry of mixed rare earth and adhesive layer is prepared, and the mixed rare earth is applied to the side of the adhesive layer near the basalt fiber reinforced board. The adhesive layer configuration is completed, and the product structure is laid, mold is closed, and lamination curing is performed. Cutting and mold operating surface finishing are also performed.

Benefits of technology

The consistency between the mixed rare earth adhesion and the state of the preceding plate components was achieved. The processing link between the basalt fiber reinforced board and the adhesive layer was fixed. The adhesion surface of the mixed rare earth corresponds to the contact surface of the basalt fiber reinforced board and the interlayer position in the subsequent product structure laying. A continuous correspondence between the adhesive layer type and the mixed rare earth adhesion state was established, forming a unified product structure laying link.

Abstract

The present application relates to the field of basalt fiber composite material preparation, and particularly relates to a basalt fiber mixed rare earth element preparation method for unmanned aerial vehicles. The method comprises the following steps: performing layering, closed system setting and baking curing based on a mold operation surface to obtain a basalt fiber reinforced plate; performing oven baking and stability state determination, and then performing gating determination on the bonding layer laying state and the mixed rare earth adhesion state to obtain the mixed rare earth adhesion state; performing solution slurry configuration of the mixed rare earth and the bonding layer, and performing one-side adhesion processing on the side of the bonding layer close to the basalt fiber reinforced plate to obtain a mixed rare earth bonding layer; finally, performing product structure laying of the basalt fiber reinforced plate and the bonding layer, mold laminating curing and cutting arrangement to obtain a final product. The present application precisely controls the introduction time of the mixed rare earth through state gating, and limits the spatial position of the mixed rare earth through one-side adhesion of the interface, thereby significantly improving the interface bonding strength of the composite material and the preparation consistency.
