The invention relates to additive manufacturing and more specifically to apparatuses and methods for producing large carbon fiber parts with high processing rates.
The invention relates to additive manufacturing and more specifically to apparatuses and methods for producing large parts with high deposition rates.
Conventional fused deposition manufacturing methods rely on thermoplastic deposition materials. The present invention involves additive manufacturing that uses reactive polymers as deposition materials. Reaction takes place following deposition.
The invention relates to additive manufacturing and more specifically to materials and methods for producing articles at room temperature.
Conventional preparation of Fused Deposition Manufacturing (FDM) fiber relies on melting and mixing of polymers in screw-type extruders. Recent tests have shown that this process is difficult when second phase reinforcement is included in the form of a fiber.
A method has been developed at ORNL that selectively dissolves both aluminum and magnesium from aluminum based alloys in a non-aqueous solvent.
The use of this invention enables the use of bonding using low-pressure (pressure < 1.7 MPa = 250 psi) sinterable silver as the interconnection or bonding layer medium using sufficiently high-temperature (temperature < 300°C = 500°F), pressurized gas (air or inert gas).&
The invention relates to electric machines for use in electric or hybrid-electric vehicles and more specifically to a motor and generator arrangement with a reduced axial length.
During the manufacturing process, variations in the dielectric material may occur that affect its electrical or physical properties in ways that impact the quality of the finished product.
Plastic zone extrusion may be provided. First, stock may be placed in a chamber. Then frictional heat may be generated within the stock to heat the stock to a plastic zone of the stock in the chamber.
