[PROBLEM] An object is to provide a reinforcing nonwoven for a foam-molded article, which makes it possible to further improve a mold-setting-property of the reinforcing nonwoven, and makes it possible to foam-mold a seat efficiently. [SOLUTION] A nonwoven for reinforcing a foam-molded article, the nonwoven comprising: a reinforcing nonwoven layer, and a resin layer; wherein, the resin layer overlaps the reinforcing nonwoven layer, a resin for the resin layer has a softening point A of not lower than 20°C and not higher than 60°C, and the nonwoven has an air permeability of not lower than 30 cc/cm 2 /sec and not higher than 300 cc/cm 2 /sec.

A cylindrical case includes: a case main body 10 made of a composite material of reinforcing fibers impregnated with a thermosetting resin; and a groove 12 disposed annularly at one end of the case main body 10. A peripheral wall 10a of the case main body 10 is formed by alternately laminating a biaxial fabric layer 13, which includes a biaxial fabric 13A of a non-crimp structure composed of reinforcing fiber bands 13a, 13b having an orientation angle of ±45°, and a roving layer 14, which includes a roving 14A composed of a bundle of reinforcing fibers extending along the circumferential direction. A groove wall 12a of the groove 12 is formed by alternately laminating the biaxial fabric layer 13, which continues to the case main body 10 side, and a triaxial fabric layer 15, which includes a triaxial fabric 15A of a non-crimp structure composed of reinforcing fiber bands 15a, 15b having an orientation angle of ±45° and a reinforcing fiber band 15c having an orientation angle of 0°. It is possible to secure high torsion strength and torsion rigidity of the entire cylindrical case, in a case where the cylindrical case is a fan case which is made of a composite material consisting of reinforcing fibers and a thermosetting resin as the raw material and has an annular groove.

A prosthesis (10) including a support structure (22) for enhancing kink and/or crush resistance. The support structure (22) is connected to an outer surface (16) of the prosthesis (10) and includes at least two components (23, 24), one of which has a lower melting point than the other. The component with the lower melting point is used to connect the support structure (22) to the outer surface of the prosthesis (10).

Fibrous preform for a hollow blade of a turbomachine, such a hollow blade and a method for manufacturing such a hollow blade. The preform comprises a first fibrous structure (41') obtained by three-dimensional weaving and comprising at least one main longitudinal portion (46, 47) able to form essentially an air foil pressure-face wall, a second fibrous structure (42') obtained by three-dimensional weaving and comprising at least one main longitudinal portion able to form essentially an air foil suction-face wall; the first and second fibrous structures (41, 42) furthermore each comprising a first connecting zone (43), extending along the front edge of their respective main longitudinal portion (46), secured to one another and forming a first connecting portion (43) of the preform and a second connecting zone (44), extending along the rear edge of their respective main longitudinal portion (46, 47), secured one to the other and forming a second connecting portion of the preform (44); the main longitudinal portions (46, 47) of the first and second fibrous structures (41', 42') being non-attached so as to leave between said main longitudinal portions (46, 47) a space (D2) able to form an air foil hollow.
摘要:
A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at Ieast one consolidated fibrous insert having an outer surface and including at Ieast one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activafable material.
