A method for producing a polyimide tubular member includes preparing a polyimide precursor solution, heating the polyimide precursor solution, coating a core with the heated polyimide precursor solution to form a coating film, drying the coating film, and baking the dried coating film to perform imidization.

In a process for building tyres for vehicle wheels, at least one tread band (9) or other elastomeric component of a tyre (2) is made by applying at least one continuous elongated element (14) according to a plurality of turns (C) around a forming drum (15) rotating around a geometric rotation axis (X) thereof. The continuous elongated element (14) is made by the action of extruding a first material through an extrusion nozzle (16), to form an inner core (33) of said continuous elongated element (14) exiting from an outlet opening (18) of the extrusion nozzle (16). During the extrusion, a second material different from the first material is conveyed around the first material, at the extrusion nozzle (16) and upstream of the outlet opening (18), to form a coating layer (32) which entirely surrounds the inner core (33).

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles non-covalently interacting with at least a portion of a polymer material via - bonding, hydrogen bonding, electrostatic interactions stronger than van der Waals interactions, or any combination thereof. The piezoelectric particles may be dispersed in the polymer material and remain substantially non-agglomerated when combined with the polymer material. The polymer material may comprise at least one thermoplastic polymer, optionally further including a polymer precursor. The compositions may define an extrudable material that is a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component. Printed parts having piezoelectric properties may be formed using a composite filament comprising a plurality of piezoelectric particles dispersed in a thermoplastic polymer.
