A system for pultruding a beam comprises a pulling mechanism continuously pulling on a preform of yarns including a thermoplastic matrix and fibers, the pulling mechanism being downstream of the system. A pultrusion die has a tapering channel portion heated such that the preform is at a desired low viscosity temperature for resin in the thermoplastic matrix to impregnate the fibers. A cooling tube is at a downstream end of the pultrusion die. A cooling module is spaced from the pultrusion die by the cooling tube, the cooling module to cool the cooling tube before the preform reaches the pulling mechanism, wherein the cooling tube defines a cooling channel. A pultrusion mandrel may be present.

Pultrusion system with cooling stage and method therefor

A metallic ink for solvent-cast 3D printing, the ink comprising a solution or a gel of a polymer in a volatile solvent, and heat-sinterable metallic particles dispersed in the solution or gel, wherein the particles are present in a particles:polymer weight ratio of more than about 85:15, is provided. There is also provided a method of manufacturing this ink and a method of manufacturing a solvent-cast metallic 3D printed material using this ink.

A system for pultruding a beam, such as a pultruded beam of natural fibers, comprises a pulling mechanism continuously pulling on a preform of yarns including a thermoplastic matrix and fibers, the pulling mechanism being downstream of the system. A sequence is provided in the system and has a pre-heating module to pre-heat the preform. A first die has a tapering channel portion heated such that the preform reaches a desired low viscosity temperature for resin in the thermoplastic matrix to impregnate the fibers. A vacuum module has a vacuum cavity to remove air from the preform exiting the first die. A second die has a tapering channel portion heated such that the preform is at the desired low viscosity temperature for resin in the thermoplastic matrix to further impregnate the fibers. A cooling module to cool the beam before the beam reaches the pulling mechanism. A system for pultruding beams is also provided.

Pultruded beam reinforced with natural fibers, pultrusion system and method therefor

Composite fasteners, associated blanks and also methods and apparatus for the installation of such fasteners are disclosed. An exemplary composite rivet () disclosed comprises an elongated body including braided reinforcement fibers () embedded inside the body and supported in a matrix material (). Also disclosed are structural assemblies comprising composite fasteners and panels or other parts comprising composite and/or other materials.

Composite rivet blank and installation thereof

A method and device of positioning a ply of material for a composite component along an arcuate surface are presented. The ply comprises two end portions and a plurality of fiber tows extending longitudinally between the two end portions. The arcuate surface has a curved edge and a planar surface extending from the curved edge. The method comprises placing a first longitudinal edge portion of the ply along the curved edge; and rotating at least one of the two end portions away from the arcuate surface about a pivot axis normal to the ply, so as to cause sliding of at least some of the plurality of fiber tows relative to each other, and substantial aligning of the plurality of fiber tows in a curved direction along the arcuate surface. A method of positioning a ply of material for a composite component onto a curved mandrel is also presented.
