Expandable bladders as tooling for composite parts
Systems and methods are provided for utilizing pellet-loaded bladders to consolidate and/or harden composite parts. One embodiment is a method for fabricating a composite part. The method includes laying up a preform that is made of fiber reinforced material and that includes a cavity, inserting one or more bladders that are loaded with expandable pellets into the cavity, inflating the bladders in response to a triggering condition, consolidating the preform while the bladders are inflated, deflating the bladders, and removing the bladders from the cavity.
Disposable mold core, method for producing a component, and the component itself
A disposable mold core for producing a fiber-reinforced component includes a support core having a granulate and a binder. The support core has a hard shell formed of the binder and the granulate, and an inner core which is binder-free and formed of the granulate. A related method of producing a fiber-reinforced component is disclosed.

MOLD CORE FOR PRODUCING A COMPONENT COMPOSED OF FIBER COMPOSITE MATERIAL
A mold core for producing a component of fiber composite material with a cavity. The mold core makes a particularly simple and efficient demolding process possible by a mold core extending along a longitudinal axis and which is in the form of a hybrid core and which includes, viewed in a cross section perpendicular to the longitudinal axis, a first core portion and a second core portion, wherein the first core portion is formed from a first material with high stiffness and low coefficient of thermal expansion, and wherein the second core portion is formed from a second material that differs from the first material, and is configured such that, under predetermined conditions, its form changes in a predetermined manner such that removal of the mold core from a cavity in the cured component is made easier.
Applicator systems for applying pressure to a structure
An applicator assembly for applying pressure to a composite structure includes an external frame, an applicator casing disposed substantially within the external frame, and an applicator disposed substantially within the applicator casing. The applicator casing includes a first membrane, and a first jamming material disposed within the first membrane. The applicator includes a second membrane, and a second jamming material disposed within said second membrane.

A MOULDING METHOD FOR MAKING A MONOLITHIC COMPONENT INTERNALLY PROVIDED WITH AT LEAST ONE CAVITY INSIDE
A molding method for making a monolithic component made of C-SMC and internally including a cavity, including preparing a press including first and second half molds and movable side carriages defining a molding space, and placing a core inside the molding space. The core comprises a membrane, delimiting a containing space shaped to form the cavity, and at least one connector engaged with the membrane. The method includes wrapping a charge of material to be molded around the core, fixing the core inside one between the first and the second half molds, and filling the containing space of the membrane with a filling material. After closing the half molds, applying a molding pressure and then emptying the containing space of the filling material and, after opening the half molds, removing the core from the molded monolithic component.
