Abstract:
1. A method for manufacturing a fiber-reinforced composite sabot comprising the following steps: preparing a plurality of fiber mats having various orientation properties and forms by cutting fabric mat; forming a pre-formed fabric object by laminating the plurality of fiber mats and stitching with reinforcing material; forming a composite material by inserting the pre-formed fabric object into a vacuum assisted resin transfer molding apparatus to inject resin into the preformed fabric object, wherein the formed composite material has a size sufficient to form a piece of the sabot by mechanically processing the formed composite material, the piece having a size corresponding to one third of the sabot; mechanically processing the formed composite material to form a first piece of the sabot; forming second and third pieces of the sabot by repeating the steps recited above for forming the first piece of the sabot; and forming the sabot by combining the three pieces.
