Method for producing a profile that has a re-entrant angle in a composite material from a stack of layers of fibres
A method for producing, in a composite material, a component that has a re-entrant angle, includes stacking layers of fibers which have been pre-impregnated with a resin so as to obtain a preform and placing the preform in a tooling fixture in order to subject it to a polymerization cycle including a temperature cycle, with a temperature-increase phase and at least one soak at which the temperature is maintained, and a pressure cycle on the outside of the tooling fixture with a pressure-increase phase and a pressure-hold phase, with the layers of pre-impregnated fibers being able to slip against one another when the temperature of the temperature cycle is equal to or higher than a threshold temperature Tf dependent on the resin. The temperature-increase phase includes a soak at a temperature higher than or equal to Tf, the soak beginning before the end of the pressure-increase phase.
FIBER-BASED SURGICAL IMPLANT AND METHOD OF MANUFACTURE
A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20° C. to +170° C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.
Fluid distribution material for absorbent articles
A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.

Deformed Web Materials
Deformed web materials are disclosed. The web materials have discrete deformations formed therein. The deformations may be features in the form of portions of a web with apertures therein, protrusions, depressed areas, and combinations thereof. These features may extend out from the surface on one side of the web, or from both of the surfaces of the web. Different features may be intermixed with one another.
