Abstract: A forming-material connecting device includes a cutter that cuts a forming material constituted by plural continuous fiber bundles being impregnated with a resin material and supplied in a supply direction corresponding to an extending direction of the plural continuous fiber bundles. The cutter cuts at least a portion of the plural continuous fiber bundles. The forming-material connecting device also includes a joining portion joining portions of the forming material, which are cut by the cutter at a cutting point in the forming material, on a downstream and upstream side with respect to the cutting point in the supply direction by heating to join the resin materials of the portions of the forming material, or the joining portion joins a preceding forming material's trailing end portion and a leading end portion of a following forming material by heating to join resin materials of the preceding forming material and following forming material.

Abstract: Surface-treated polymeric particles which are dispersible in water or an aqueous solution without the aid of any surfactant. Surface treatment of hydrophobic polymeric particles is carried out to increase the surface energy and to render the surfaces of the particles hydrophilic, thereby eliminating the need for a surfactant to disperse the polymeric particles in water or an aqueous solution. As such, a surfactantless slurry can be formed from the surface-treated particles for the fabrication of fiber-reinforced thermoplastic composite structures.
