The invention belongs to the technical field of materials, relates to the technical field of
fiber reinforced composite materials, and particularly relates to a molding method of a unidirectional reinforced
composite material with carbon nanotubes perpendicular to a
fiber direction. The molding method comprises the working procedures of glue solution preparation,
nanotube orientation, glue dipping, winding and molding. The orderly arrangement of the carbon nanotubes (CNTs) in a glue solution is realized by applying a direct-
current electric field to the CNTs dispersed in resin, and a direct-
current electric field is applied again between an
extrusion roller and a
drying chamber to perform secondary orientation on the CNTs dipped on the surface of
fiber bundles, so that the orientation degree of the CNTs in the
composite material is high, and the interlayer mechanical properties and the electrical
conductivity are substantially improved. The molding method of the unidirectional reinforced
composite material with the carbon nanotubes perpendicular to the fiber direction provided by the invention is easy to operate and control, low in requirements on equipment transformation, less in investment, quick in effect, widely applicable to winding systems with a semi-dry process, and especially applicable to the molding of unidirectional prepregs and composite materials thereof.
