The present disclosure relates to a film usable for roll-to-roll processing of flexible electronic devices, the film comprising a composite material comprising a polymer and hexagonal boron nitride particles, wherein the hexagonal boron nitride particles comprise platelet-shaped hexagonal boron nitride particles. The present disclosure further relates to a process for producing said film, and to the use of said film.

A method of making a waveguiding optical component includes processing a polymer optical material to form a billet having an axis of light transmission and having residual stress maintaining a transverse extent of the billet; placing the billet into a mold, the mold being configured to constrain transverse expansion of the billet according to a desired shape of the waveguiding optical component; and heating the billet in the mold to induce relaxation of the residual stress and corresponding transverse expansion of the billet, thereby forming the billet into the waveguiding optical component with the desired shape. An alternative method begins with a collection of individual canes or fiber segments which are fused during the heating process, bypassing a separate process of forming a billet.

Provided is a bevel gear component including a plurality of teeth protruding in an axial direction, extending toward an outer peripheral side, and arranged at equal pitches in a circumferential direction, the bevel gear component including a fiber material having a shape corresponding to an arrangement pattern of the plurality of teeth and wound around a center axis.

A method of making a carbon fiber wave spring includes forming a disc-shaped ring from prepreg carbon fibers. The disc-shaped ring is then formed into a desired wave shape. The disc-shaped ring in the wave shape is then cured to form a wave spring.

Provided is a fiber-reinforced resin bolt having a strength higher than that of a conventional fiber-reinforced resin bolt. A fiber-reinforced resin bolt 1 formed by a winding step of winding a CFRP resin tape 14, which is formed in a band shape by integrating CFRP 12 with a thermosetting resin in such a manner that the CFRP 12 is oriented in a longitudinal direction, so that the CFRP 12 is arranged concentrically around a winding axis, thereby forming a CFRP resin tape layer 10; and a curing step of placing the CFRP resin tape layer 10 formed by the winding step in a die 40 whose inner wall surface is formed with a screw shape, pressurizing the die 40 in which the CFRP resin tape layer 10 is placed from one direction of the winding axis to the other, and heating the die 40 with a heater 82, thereby curing the resin containing the CFRP resin tape layer 10.

The present invention relates to a process for producing a hot melt adhesive (HMA) material, preferably hot melt pressure sensitive adhesive (HMPSA) material, having a substantially tack-free coating comprising a novel moulding and spraying step, wherein said HMA material, preferably HMPSA material, can be easily handled, packed and transported for further use. In addition, the present invention relates to a corresponding device for producing a hot melt adhesive (HMA) material, preferably hot melt pressure sensitive adhesive (HMPSA) material, having a substantially tack-free coating.

A punch for the compression molding of plastic material for forming capsules for containers closure, wherein the punch includes a stem portion made of steel and a head portion made of copper alloy screwed to the stem portion, wherein a separation interface between the stem portion and head portion includes a passage for gas that reaches a bottom surface of the punch delimitating one forming cavity where the compression molding of the plastic material occurs, and wherein one channel internal to the head portion communicates with the passage for gas to enable extraction of gas out of the forming cavity.

An objective of the present invention is to provide a method for producing a cork stopper by compression molding cork grains, which can provide a cork stopper excellent in sealability and safety. There is provided a method for producing a cork stopper, comprising: mixing cork grains and an adhesive; compression molding the mixture to give an intermediate; and then heating the intermediate to expand the cork grains.

A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.
