A device for consolidating a fiber preform to obtain a panel made of composite material of large dimension, comprising an induction heating system configured to generate at least one electromagnetic field in a heating zone, at least one susceptor incorporated in a first die tool supporting the fiber preform and/or a cladding covering the fiber preform, each susceptor producing a uniform heating of the fiber preform when it is positioned in the electromagnetic field of the induction heating system, and a mechanism configured to induce a relative movement between the induction heating system and the first die tool so that all the fiber preform crosses the heating zone.

A method for producing an object or component, which is at least partially formed from plastic, by supplying energy for solidifying the plastic of the object or component to the plastic to be solidified by at least one energy conductor, such as an optical fiber, in the component to be produced, and the solidification of the plastic can be accelerated by the direct energy introduction into the object or component to be produced.

In an injection molded product of the invention, an unevenness forming portion having unevenness formed by thermal expansion of thermally expandable capsules is formed. The injection molded product includes a highly expanded portion that is formed at a surface side of the unevenness forming portion in a thickness direction of the injection molded product and in which the thermally expandable capsules are thermally expanded, and a main body portion that is a portion adjacent to the highly expanded portion in the thickness direction and in which the thermally expandable capsules are substantially not thermally expanded. The thickness of the highly expanded portion is a half or smaller than the thickness of the injection molded product in the unevenness forming portion, and a polymer material of the highly expanded portion and a polymer material of the main body portion are the same polymer material.

A manufacturing method of a resin article having a plurality of filamentous projections that are formed in a contact surface of a resin article body may include a thrusting step to thrust acute-angled leading edges of plate-shaped metal parts into the contact surface of the resin article body, a heating step to heat the plate-shaped metal parts before or during the thrusting step, and a pulling out step to pull out the plate-shaped metal parts in a condition in which portions of the resin material of the resin article body is melted around the leading edges of the plate-shaped metal parts and in which melted resin portions are formed on unmelted portions of the resin material of the resin article body.

A mold for forming a flange of a wind turbine blade comprising a first flange portion including a plurality of lamina and having a generally planar shape and a second perpendicular flange including a plurality of lamina. A plurality of copper wires are disposed within the lamina for conducting heat delivered from a base portion through the first and second flange portions. The mold is free of fluid conduits with the flange portions moveable relative to the base portion.

A formable resin sheet includes a base, a thermally expansive layer provided on a first side of the base and containing a thermally expandable material, a thermal conversion layer containing an electromagnetic wave heat conversion material that converts electromagnetic waves to heat and provided on one of the thermally expansive layer and a second side of the base, and an electrically conductive layer that is electrically conductive and is provided on another one of the thermally expansive layer and the second side of the base. At least a portion of the electrically conductive layer is provided so as to be opposite at least a portion of the thermal conversion layer, with the base and the thermally expansive layer interposed therebetween.

An antimicrobial article includes a flexible substrate; and a plurality of first protrusions which is formed on at least one surface of the substrate, includes a crosslinked polymer resin and antimicrobial materials dispersed in the polymer resin, and is formed with first grooves in which at least one of bacteria, fungi, and viruses may be received. According to the present disclosure, in the antimicrobial article and the manufacturing method thereof, it is possible to greatly improve the antimicrobial effect of the antimicrobial article by minimizing a distance between bacteria, fungi, or viruses attached to the antimicrobial article and antimicrobial materials of the antimicrobial article to maximize the quantity of the antimicrobial materials that affect the bacteria, fungi, or viruses.

The present disclosure provides methods for printing at least a portion of a three-dimensional (3D) object, comprising receiving, in computer memory, a model of the 3D object. Next, at least one filament material from a source of the at least one filament material may be directed towards a substrate that is configured to support the 3D object, thereby depositing a first layer corresponding to a portion of the 3D object adjacent to the substrate. A second layer corresponding to at least a portion of the 3D object may be deposited. The first and second layer may be deposited in accordance with the model of the 3D object. At least a first energy beam from at least one energy source may be used to selectively melt at least a portion of the first layer and/or the second layer, thereby forming at least a portion of the 3D object.

An additive manufacturing system is disclosed that heats a feedstock and a workpiece in preparation for depositing and tamping the feedstock onto the workpiece. The system comprises a first laser/optical instrument pair for precisely heating the feedstock and a second laser/optical instrument pair for precisely heating the workpiece. The laser beam from each laser is shaped into an ellipse and each beam is rotated around an angle of rotation to ensure that the feedstock and the workpiece are properly heated. The system employs feedforward, a variety of sensors, and feedback to adjust the angle of rotation of each laser beam.
