摘要： Example approaches are disclosed for manufacturing composite or fiber reinforcement preforms. Liquid, fibrous, binding and potentially other materials are mixed into a composite mixture slurry in a slurry container. A porous tool having a specific porous outer surface portion approximating a specific exterior surface portion of a spatial shape of a final product is immersed in the slurry container. A suction pressure is applied to draw a portion of the fibrous material intermixed with a corresponding portion of the binding material in the slurry onto the specific outer surface portion. The porous tool attached with the wet preform is removed from the slurry container. The wet preform is partially dried into a partially dried preform attached to the porous tool. The partially dried preform is dried, solidified and/or consolidated and/or injected with a resin and cured into a solid composite preform of the spatial shape of the final product.
