Described herein are additive manufacturing systems and methods for printing 3D objects.

The present invention provides an anti-slip apparatus. The apparatus forms a planar, layered member and includes a glass-reinforced plastic (GRP) layer, a first resin layer, an abrasive or anti-slip material layer, and a second, top resin layer. Also provided is a template apparatus arranged to enable the installation/application to a floor or surface of an anti-slip apparatus as herein described.

An assembly includes a first part and a second part separate from the first part, the first and second parts being intended to be in frictional contact, the first part being made of an organic matrix composite material that has, on its surface, an abrasion-resistant area including a resin that contains polytetrafluoroethylene particles, the polytetrafluoroethylene particles being only present at the surface of the first part, and the second part being made of an organic matrix composite material and being in contact with the abrasion-resistant area of the first part.

The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.

A method for producing a reinforcing bar by pultrusion, the method comprising the steps of: a) providing a source of fibres; b) assembling the fibres into a bundle; c) impregnating the bundle with a thermosetting resin; d) eliminating excess resin from the bundle; e) compressing the bundle in a centripetal manner; f) exposing the bundle to a radiant energy source; g) spraying particles onto a surface of the bundle; and h) exposing the bundle to radiation in order to initiate, on the surface of same, the polymerisation of the resin. The present invention also concerns a system provided with corresponding devices in order to be able to implement the method. The present invention also concerns a reinforcing bar obtained with the described method and/or system.

A process control system and a method for process control of a solid-state additive manufacturing system capable of performing various additive processes, such as joining, additive manufacturing, coating, repair and others, are disclosed. The process control system is capable of simultaneous measuring, monitoring and controlling multiple process variables, viz. material temperature, actuator down force, tool force (or torque), tool position, tool angular and transverse velocity, spindle torque (angular velocity), filler flow rate, filler composition, track width, inert gas flow rate and others. A feeding system for continuous supply of filler material to the solid-state additive manufacturing system is also disclosed. The filler material can be in a form of a powder, granules, briquettes, beads, flakes, wires, rods, films, scrap pieces, sheets, blocks or their combinations. Methods for generation of different periodic and non-periodic structures and joints using the process-controlled solid-state additive manufacturing system are also disclosed.
