LUBRICANT-INFUSED MOLDS AND USES THEREOF
The present application relates to lubricant-infused molds such as omniphobic lubricant-infused molds and uses thereof, for example, in processes for fabricating molded objects such as microfluidics devices. Such processes can comprise coating a mold with a layer comprising a lubricant-tethering group to obtain a tether-coated mold, depositing a lubricant on the tether-coated mold to obtain a lubricant-infused mold (LIM), depositing a molded object precursor into the LIM and solidifying to obtain the molded object, and removing the molded object from the LIM.

Method for producing composite material joined body
A method of the invention produces a composite material conjugate in which a first composite material and a second composite material are adhered without using an adhesive, wherein a first prepreg laminate to which a release member is attached is cured to form the first composite material, the release member being made of a material that does not transfer silicone and fluorine to the first prepreg laminate, after detaching the release member from the first composite material, surface treatment that imparts polar functional groups to the surface of the first composite material to which the release member was bonded is carried out to activate the surface, a second prepreg laminate is placed directly on the activated surface of the first composite material, and the second prepreg laminate is cured to form a second composite material adhered to the first composite material.

Device for producing a component from fiber composite material
The invention relates to a device for producing a component made from a fiber composite material from a semi-finished fibrous product by means of a multi-part molding and infiltration tool with tool parts, the molding functional surfaces thereof forming, when the tool is closed, a cavity that defines the component. The device is characterized in that the tool (1) has a sealing frame (2, 16, 18, 20, 21, 22) which is designed as a hollow body and in which the semi-finished fibrous product (3) can be arranged, and the tool parts (4) are configured and can be associated with the sealing frame (2, 16, 18, 20, 21, 22) such that, when the tool (1) is closed, the tool parts (4) are connected tightly to the sealing frame (2, 16, 18, 20, 21, 22).

Acetaldehyde scavenger treatment
A method of forming a vehicle interior foam article, the method including applying a mold release agent onto an inner surface of a mold, delivering a solution having aldehyde scavenger(s) to the mold such that a reaction of the aldehyde scavenger(s) with the mold release agent is prevented, delivering a foam material into the mold, and casting the article.
