摘要： (A) A reinforcing fiber, (B) a resin particle, and (C) a matrix resin are combined to prepare a resin composition which improves a reinforcing effect by the reinforcing fiber. The reinforcing fiber (A) contains a carbon fiber. The resin particle (B) contains a semicrystalline thermoplastic resin, the semicrystalline thermoplastic resin in the resin particle (B) has an exothermic peak in a temperature range between a glass transition temperature of the semicrystalline thermoplastic resin and a melting point of the semicrystalline thermoplastic resin, the peak being determined by heating the resin particle (B) at a rate of 10° C./min. by differential scanning calorimetry (DSC), and the resin particle (B) has an average particle size of 3 to 40 μm. The semicrystalline thermoplastic resin may be a polyamide resin having a melting point of not lower than 150° C. (particularly, a polyamide resin having an alicyclic structure and a glass transition temperature of not lower than 100° C., or a polyamide resin having a γ-type crystal structure or a degree of crystallinity of not more than 50%). The matrix resin (C) may be a thermosetting resin.

摘要： Provided is a resin composition, a filament and resin powder for a three-dimensional printer, a shaped object, and a production method for the shaped object, all of which make it easy to produce a shaped object and can improve, in shaping using a three-dimensional printer, the resistance to delamination of the shaped object and the resistance to warpage and shrinkage of the shaped object. A resin composition contains: inorganic fibers having an average fiber length of 1 μm to 300 μm and an average aspect ratio of 3 to 200; and a thermoplastic resin and serves as a shaping material for a three-dimensional printer.

摘要： A free-standing solid composite intumescent structure has at least one bendable metal mesh, preferably at least two, secured on or in a bendable intumescent sheet material. The structure is bendable by a bending force into a shape at a temperature above −10° C. while retaining the bended shape when the bending force is removed. The intumescent sheet material has 10 wt % or more, based on total weight of the sheet material, of a polymeric resin; inorganic filler; and, an intumescent component. Fire protection barriers can be made from the free-standing solid composite intumescent structure, which can be used in fire protection systems where the fire protection barrier is installed on a substrate, for example steel building elements.

摘要： A composition includes a thermosetting resin and a plurality of polymer nanoparticles at least partially dissolved in the resin. The resin has a gradient of mechanical properties around each location of the at least partially dissolved polymer nanoparticles. Each gradient extends from a particle center toward the resin surrounding the polymer nanoparticle.
