Method for manufacturing an absorbent article, the method including: while a lower bandlike member is transported in a transport direction, a process in which a cutting position is determined and an adhesion area is formed by putting adhesive on each side of the cutting position of the lower bandlike member in the transport direction; a process in which elastic members are placed so that a part of each of the elastic members overlaps the adhesion area, the elastic members being stretched in the transport direction; a process in which an upper bandlike member is stacked on and adheres to the lower bandlike member and the elastic member on the adhesion area; a process in which the lower bandlike member and the upper bandlike member are folded on the center in the intersecting direction; a process in which a welded section on which the lower bandlike member and the upper bandlike member are to be welded to each other is formed on each side of the cutting position in the transport direction; a process in which and the lower bandlike member, the upper bandlike member and the elastic members are cut together on the cutting position, a lower exterior member and an upper exterior member which are shaped in the form of underpants are cut and separated, the elastic members which are stretched in the transport direction contract towards the adhesion area from positions at which the elastic members are cut, the contraction being performed while the elastic members shifting relative to the lower exterior member and the upper exterior member.

A process includes disposing a mandrel assembly within a mold cavity bounded by mold forming surfaces. The mold is closed, first portions of the mandrel assembly seal against mold forming surfaces, and a continuous volume shaped as a node element is defined between second portions of the mandrel and the mold forming surfaces. A composite material is injected into the mold cavity filling the continuous volume, and cured forming the node element. The mandrel assembly is removed in sections exposing a node element opening. Tube-skeletons are inserted one each into openings of the node element, each tube-skeleton comprises foam core supported glass or carbon fabric materials. A resin material is injected into the mold cavity, such that the resin material permeates through the fabric material into a node element interior via the openings. The injected resin material is cured, thereby forming tube elements joined to the node element.

The curable composition includes: a) no more than 5.0 wt % of a thermoplastic polymer; b) no more than 5.0 wt % of nano-sized core-shell particles; c) no more than 5.0 wt % of nano-sized inorganic particles; d) an epoxy resin component; and e) one or more amine curing agent(s),
wherein the initial viscosity of said curable composition is no more than 5 Poise at a temperature within the temperature range of from about 80 C. to about 130 C.
