Abstract: A method for preparing a monodomain liquid crystal elastomer smart fiber incudes: during cross-linking process of the liquid crystal elastomer, drawing of liquid crystal elastomer fibers with uniform diameter from a polymer solution when the viscosity of the cross-linked polymer solution increases to a point where filaments can be drawn; heating by an infrared lamp to form filamentous liquid crystal elastomer fiber; natural air drying to remove excess solvent in the fiber; and stretching and collection of the fiber, followed by placement of the fiber, whereby the monodomain liquid crystal elastomer smart fiber is obtained. The method uses a one-step liquid phase drawing method, which is simple and suitable for large-scale industrial production and enables continuous preparation of high-strength, large-deformation reversible shape memory liquid crystal elastomer fiber with uniform and controllable diameter, breaking through the limitations of the size, strength and driving performance of existing liquid crystal elastomers.

Abstract: A semi-finished product for the manufacture of a structural component has a plurality of prepreg tapes, each having unidirectionally arranged reinforcing fibers embedded in a thermoplastic matrix material, and with a plurality of connecting strands containing a thermoplastic material. The prepreg tapes and the connecting strands are either joined to form a textile sheet structure or the prepreg tapes are arranged to form a multiaxial fabric, individual layers of the fabric being joined by the connecting strands. Further, a method for manufacturing a curved structural component from such a semi-finished product is described.

Abstract: A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane.

Abstract: A method and apparatus for the additive manufacturing of three-dimensional objects are disclosed. Two or more materials are extruded simultaneously as a composite, with at least one material in liquid form and at least one material in a solid continuous strand completely encased within the liquid material. A means of curing the liquid material after extrusion hardens the composite. A part is constructed using a series of extruded composite paths. The strand material within the composite contains specific chemical, mechanical, or electrical characteristics that instill the object with enhanced capabilities not possible with only one material.

Abstract: Methods of fabricating a hydrogel tube, and related systems, employ extrusion of a cross-linkable hydrogel solution from an annular outer nozzle of a nozzle assembly to form a cross-linkable hydrogel tube. The cross-linkable hydrogel tube is cured to form a cross-linked hydrogel tube. A second hydrogel solution can be coextruded via the axial inner nozzle to form an inner hydrogel filament coaxially positioned within the cross-linkable hydrogel tube. The cross-linked hydrogel tube can be functionalized with collagen to enable cell adhesion, and cells can be cultured on the luminal surfaces of these tubes to yield tubular endothelial layers. A 3D printed coaxial nozzle can be used to fabricate biofunctional tubular conduits that can be utilized for engineering in vitro models of tubular biological structures.

Abstract: In an example 3D printing method, an electrical conductivity value for a resistor is identified. Based upon the identified electrical conductivity value, a predetermined amount of a conductive agent is selectively applied to at least a portion of a build material layer in order to introduce a predetermined volume percentage of a conductive material to the resistor. Based upon the identified electrical conductivity value and the predetermined volume percent of the conductive material, a predetermined amount of a resistive agent is selectively applied to the at least a portion of the build material layer in order to introduce a predetermined volume percentage of a resistive material to the resistor. The build material layer is exposed to electromagnetic radiation, whereby the at least the portion coalesces to form a layer of the resistor.
