A method of manufacturing a multi-hardness and multi-elasticity foam mattress in which a plurality of foam blocks are formed integrally with each other by use of a continuous foaming process the method comprising the steps of: arranging a plurality of nozzles above one end of a molding plate; installing a separation wall between two adjacent ones of the respective nozzles arranged at the molding plate; laminating a release paper on the top of the molding plate; spraying foaming solutions from the nozzles, respectively, wherein the release paper moves in a direction toward the other end of the molding plate corresponding to a moving speed of the foaming solution; and molding a foam body having a plurality of zones where a plurality of unit foam blocks have multi-hardnesses and multi-elasticities.

A complex structure material includes a foam made of thermosetting resin and coverings made of thermoplastic resin. The foam includes a matrix and pores. At least some of the pores communicate with each other. The foam has a continuous porous structure formed by the matrix and the pores. The coverings cover inner walls of the pores in the foam.

A needle shield remover for a medicament delivery device is presented that has a metal tubular body, a proximal part, a distal part, and a substantially circular cross-section, where the tubular body is arranged with a slot extending from a distal end of the body, at least half the length of the body, towards a proximal end, such that at least the distal part of the body may flex radially outwards to exert a radially inwardly directed clamping force on a needle shield accommodated by the body.

A process for producing a thermoformable polymer/fiber composite using a fibrous substrate, an organic di- or polyisocyanate compound and a dispersion polymer.

The present invention provides a prepreg that has high impact resistance despite being an all-carbon-fiber FRP (CFRP), the prepreg moreover enabling a molding time to be set to five minutes or less and making it possible to reduce molding costs. This prepreg is obtained by impregnating carbon fiber with a matrix resin comprising a mixture of a thermoplastic resin, a thermosetting resin, and a curing agent, wherein: the thermoplastic resin is a phenoxy resin; the thermosetting resin is a urethane acrylate resin; the thermoplastic resin and the thermosetting resin are compounded in a mass ratio of 15:85-35:65 (thermoplastic resin/thermosetting resin); and the curing agent causes cross-linking to occur due to a radical polymerization reaction, and is formed so as to include first and second peroxides having mutually different initiation temperatures, initiation of the second peroxide starting at a temperature at which termination of the first peroxide occurs.

A composite structure includes: a metal member; and a thermoplastic resin member bonded to the metal member, in which the metal member has a fine uneven structure at least on a metal surface to which the thermoplastic resin member is bonded, a hardness of the thermoplastic resin member measured by a type A durometer in accordance with JIS K6253 is in a range of equal to or more than A60 and equal to or less than A95, and an acid value of the thermoplastic resin member is equal to or more than 1 mgKOH/g and equal to or less than 100 mgKOH/g. The thermoplastic resin member preferably contains a urethane-based thermoplastic elastomer, an amide-based thermoplastic elastomer, and an acid-modified polyolefin.
