The resin composite of the present invention has a polyamide-based resin expanded sheet, and a fiber-reinforced resin layer integrally laminated on a surface of the polyamide-based resin expanded sheet.

The present invention discloses a preparation method for a hollow radiator and a hollow radiator. The preparation method comprises the following steps: 1) providing a feed and an insert raw material; 2) molding the insert raw material into an insert; 3) placing the insert in a cavity of a mold, and filling the cavity with the feed by injection molding in such a manner that the insert is surrounded by the feed, thereby obtaining a green body with the insert; 4) performing debinding treatment on the green body with the insert to remove the insert, thereby obtaining the green body of a hollow structure; and 5) sintering the green body to obtain the hollow radiator. By the preparation method for a hollow radiator according to the present invention, a radiator of a complex hollow structure can be fabricated, and the heat dissipation effect of the radiator can be improved. Moreover, the airtightness and leakproofness of the radiator can be guaranteed for a long time.

The present application provides sintered porous elastomeric liquid applicators with or without flocking fibers that provide improved liquid and gel delivery properties and a comfortable experience for the user of the applicators when applying liquid to a surface, such as skin.

A photo-curable resin composition for three-dimensional shaping includes a polyfunctional radical polymerizable compound (A), a monofunctional radical polymerizable compound (B), polyethylene particles (C), and a curing agent (D). The polyfunctional radical polymerizable compound (A) is a single polyfunctional radical polymerizable compound having an ethylenically unsaturated group equivalent of 700 g/eq or more and 8,000 g/eq or less or a mixture including a plurality of types of polyfunctional radical polymerizable compounds and having an ethylenically unsaturated group equivalent of 700 g/eq or more and 8,000 g/eq or less, the ethylenically unsaturated group equivalent being a weighted average of ethylenically unsaturated group equivalents of the polyfunctional radical polymerizable compounds in terms of weight ratio. A content of the polyethylene particles (C) is 5 parts by mass or more and 50 parts by mass or less relative to 100 parts by mass of a total of the polyfunctional radical polymerizable compound (A) and the monofunctional radical polymerizable compound (B).

A method of manufacturing a folding mat includes: suctioning a first film onto a lower mold, in which a downwardly concave slit groove is formed at one end of a cavity such that a portion of the first film forms a unit fold part; inserting the unit filler over the first film; disposing a second film on an upper side of the lower mold to cover the unit filler; attaching the edge parts of the first and the second films together by using an upper mold mating with the lower mold; trimming an attachment part of the unit mats thus fabricated; fusing the unit fold part of the unit mat with the unit fold part of an adjacent unit mat; and fusing the attachment part of one of the two unit mats thus connected with the attachment part or the unit fold part of another unit mat.
