Continuous fiber reinforcement is the key to achieving higher strength
The resin or matrix holding the fiber should have no voids and is not more than 35-38% of the structure
Either high voids or lower percentage reduces the performance exponentially
Fiber Placement: Works by pulling strips of fiber-plastic tapes and pressing it onto a predefined simple shape.
Fiber Printing: Extruding the filament through a heated nozzle in X-Y layers to create a highly complex shape.
Pure polymer printing: Extruding thermoset or thermoplastic plastic through a heated nozzle in X-Y layers to create a highly complex shape.
Hybridization: A combination of fiber placement and fiber printing applied to the manufacturing process
The best place to use each approach
Composites typically comprise a polymer material and a reinforcing material, like continuous fiber. The composite material offers higher strength and stiffness compared to non-reinforced polymers due to the presence of fiber, the polymer plays the role of the stress distribution medium. Continuous fiber ensures the load is distributed across the length without a weak point.
