METHOD FOR MANUFACTURING A PART MADE OF A COMPOSITE MATERIAL COMPRISING AT LEAST ONE PORTION FORMING A FORCE-INSERTION PORTION OR LOCAL THICKENED PORTION
A method for manufacturing of a part made of composite material including pre-compacting to a predetermined shape of a mixture of a first thermosetting resin with discontinuous long fibers so as to form a first preform, pre-curing the first preform until an intermediate conversion stage corresponding to a solidification of said first resin, contacting the first preform with a second preform including a fiber structure of continuous fibers impregnated with a second thermosetting resin, polymerizing the first and second preforms so as to form a part made of composite material including a body made of composite material including reinforcement made of continuous fibers consolidated by an organic matrix provided with a portion made of composite material including reinforcement made of discontinuous long fibers consolidated by an organic matrix.
Composite laminate structures
Composite laminate structures are produced using partially cured parts. Partial curing of the parts is achieved by applying a catalyst to regions of the parts that are to be fully cured. These regions cure at a lower-than-normal temperature while remaining regions of the part remain uncured, allowing them to be co-bonded or co-cured to other structures.

DUAL CURE ADDITIVE MANUFACTURING RESINS FOR PRODUCTION OF FLAME RETARDANT OBJECTS
The present invention concerns methods of forming a three-dimensional object, and polymerizable liquids such as dual cure resins useful for making a three-dimensional object by sterolithography, such as by continuous liquid interface production (CLIP), wherein the three-dimensional object is flame retardant.
Method for joining by bonding of parts, in particular composite parts having fibrous reinforcement
A method for assembling two parts, referred to as first and second parts, the first part being produced from composite material with fibrous reinforcement embedded in a thermosetting or thermoplastic matrix, the method comprising the steps of: obtaining the first part comprising, on all or part of an outer surface, a first amorphous thermoplastic film; positioning the first part and the second part such that the first amorphous thermoplastic film is placed opposite the second part; introducing a thermosetting resin between the first amorphous thermoplastic film and the second part; at least partially polymerising the thermosetting resin. When the two parts comprise an amorphous thermoplastic film, the parts are positioned such that the respective amorphous thermoplastic films are placed opposite each other, and the thermosetting resin is introduced between the amorphous thermoplastic films.

3D-PRINTING METHODS AND SYSTEMS
The present invention belongs to the field of three-dimensional printing methods. It relates to a method for printing a three-dimensional article, to a system thereof, to the use thereof and to a three-dimensional printed article manufactured therewith. The present invention relies on the use of a liquid resin comprising cyanoacrylate-based monomers and on the use of acidic inhibitors.
Additively manufactured objects with pre-formed bonding features and methods of making the same
The present disclosure describes a three-dimensional object. The three-dimensional object includes a light polymerized body, at least one internal chamber residing within the light polymerized body, the at least one internal chamber having at least one frangible wall, and a curable component contained within the at least one internal chamber. The three-dimensional object may further include at least one channel extending inwardly from an outer surface of the light polymerized body toward the internal chamber and at least a portion of the at least one channel being adjacent to the at least one frangible wall of the at least one internal chamber. Methods of bonding an insertable object to a three-dimensional object and kits are also described.
