A system (700) for additively manufacturing a composite part (102) comprises a delivery guide (112), movable relative to a surface (114). The delivery guide (112) is configured to deposit at least a segment (120) of a continuous flexible line (106) along a print path (122). The continuous flexible line (106) comprises a non-resin component (108) and a thermosetting-resin component (110). The thermosetting-resin component (110) comprises a first part (253) and a second part (255). The non-resin component (108) comprises a first element (271) and a second element (273). The system (700) further comprises a first resin-part applicator (236), configured to apply the first part (253) to the first element (271), and a second resin-part applicator (237), configured to apply the second part (255) to the second element (273). The system (700) also comprises a feed mechanism (104), configured to pull the first element (271) through the first resin-part applicator (236), to pull the second element (273) through the second resin-part applicator (237), and to push the continuous flexible line (106) out of the delivery guide (112).

A carbon-fiber-reinforced resin cylinder for propeller shafts includes a first-carbon-fiber-reinforced resin layer having a first carbon fiber, and a second-carbon-fiber-reinforced resin layer having a second carbon fiber and being higher in strength and lower in elastic modulus than the first-carbon-fiber-reinforced resin layer. The first carbon fiber is arranged so as to extend along a longitudinal direction of the cylinder.

A stitchless highly oriented polypropylene fabric bulk bag of the type that can hold 500 to 5000 pounds (226.7 to 2268 kilograms) of bulk material includes a highly oriented polypropylene fabric top, body and bottom, with a heat fused joint providing an air tight connection between the top and body, and another air tight heat fused joint connecting the body and bottom. A fill spout and discharge tube may also be provided with an air tight heat fused joint connecting the fill spout to the top and another air tight heat fused joint connecting the discharge spout to the bottom. Heat sealing machinery include heat seal bar assemblies that can self-align during heat-sealing to apply even pressure to all areas being heat sealed. A heating element is of single piece construction and can include end coupler portions as part of the single piece construction. Carrier plates used in a heat-sealing assembly line guide parts placement, provide quality checks for parts placement, and tooling set-up for machinery.
