A microcapsule for use with an underwater adhesive includes a shell including nanoclay platelets and a polyurea product of an interfacial polymerization of a polyamine and an aromatic polyisocyanate. The microcapsule further includes a core composition encapsulated by the shell. The core composition includes a base catalyst for formation of a polyurethane, a polyol, and a hydrophilic solvent.

A fiber reinforced resin hollow molded body 30 in which a resin-integrated fiber sheet is used. The resin-integrated fiber sheet includes unidirectional continuous fibers that are spread fibers of a continuous fiber group and arrayed unidirectionally in parallel, and thermoplastic resin that is present at least on a surface of the unidirectional continuous fibers. In the hollow molded body, in a state where the resin-integrated fiber sheet or a plurality of the resin-integrated fiber sheets 30 are stacked, the resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are wound to produce a wound body having an overlapping portion. The thermoplastic resin is impregnated in the unidirectional continuous fibers. The resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are consolidated.

The present invention relates to a multilayer, flexible, porous, dissolvable solid sheet article.

Mattresses, cushions, and body-support mats or pads include a plurality of layers extending in a depth direction from a resting surface, where the resting surface is capable of supporting user(s), to a lower surface, the lower surface being opposite the resting surface. The plurality of layers include a comfort layer that forms an upper layer proximate to the resting surface, where the comfort layer includes deformable walls separated by voids and the deformable walls include a plurality of fiber strands embedded in a cushioning media.
