The present invention relates to a composition comprising (i) an unsaturated dicarboxylic acid, an ester or an anhydride thereof and (ii) aliphatic diol, (iii) dianhydrohexitol, (iv) cycloaliphatic diol and/or aromatic aliphatic diol, and (v) an amide-forming agent. Further, the invention relates to an unsaturated polyesteretheramide obtainable by condensation of the composition of the invention and to an unsaturated polyesteretheramide resin comprising the unsaturated polyesteretheramide and a reactive diluent. The invention further relates to a thermoset with high thermo-mechanical properties.
Method and apparatus for the additive manufacturing of a three-dimensional workpiece
The invention relates to a method for the additive manufacturing of a three-dimensional workpiece, in the case of which a thermoplastic material is transferred into a liquid phase by heating and is applied selectively to locations which are predetermined by the shape and the dimensions of the workpiece, wherein the workpiece is constructed in layers on a substrate carrier. According to the invention, in order for the material to be cooled and hardened, the workpiece, which is constructed in layers on the substrate carrier, is moved from a heated construction chamber into a cooling chamber, which is separate from the construction chamber. The invention also relates to an apparatus for the additive manufacturing of a three-dimensional workpiece.

Active cooling system for manufacturing composite structures
A composite manufacturing system is provided. The composite manufacturing system comprises a fiber placement head, a compaction roller associated with the fiber placement head, and a temperature regulation system associated with the compaction roller. The temperature regulation system is configured to actively control a temperature of the compaction roller. The temperature regulation system comprises a number of temperature sensors, a cooling system, and a controller. The number of temperature sensors are configured to detect the temperature of the compaction roller. The cooling system is associated with the compaction roller and is configured to cool the compaction roller. The controller is in communication with the number of temperature sensors and the cooling system. The controller is configured to cool the compaction roller such that the temperature is below a threshold temperature.
Backup cooling device for hot isostatic press
A backup cooling device intended for a hot isostatic press, the press comprising a compression chamber, a tank containing a gas and a first gas flow circuit for the gas to flow between the gas tank and the compression chamber. The backup cooling device comprises a tank containing a coolant equipped with a first heat exchanger for exchanging heat between the gas and the coolant, a coolant flow circuit forming a closed loop including the tank and a cooling circuit arranged around the compression chamber, a second gas flow circuit for the gas, extending from a connecting valve connecting it to the first gas flow circuit, and including the first heat exchanger, a control module (CMD) suitable for controlling the connecting valve so as to open it in the event of a malfunction of the hot isostatic press, and otherwise to close it.
High performance cooling system
The present invention relates to an external cooling system for a molten film tube produced by a blown film tubular extrusion process, comprised of one or more enclosures with one or more respective cavities that directly receive a portion of cooling gas emanating from one or more associated cooling elements. Each enclosure includes a port containing a variable exhaust device and optional flow buffer, acting to maintain a pressure differential between the cavity and an adjacent inside volume of the molten film tube, adjustable to optimize molten film tube stability cooling element efficiency and spaced apart dimension between cooling elements. Additionally, at least one cooling element is provided, comprised of a divergent cooling element with a divergent cooling interface containing a cooling gas deflector spaced adjacent to the molten film tube and providing an expelled cooling gas.

Self rising board molding
A three-dimensional component is produced in a simplified molding operation. Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. Boards can be formed by laminating two or more blanks together and/or by laminating the blanks with other materials, including non-expendable materials. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. In addition, the boards or blanks may be cut to create desired shapes of parts that can be placed in the mold.
