High-rate manufacturing of thermoplastic composites with electrically and thermally conductive constituents
Provided is a method to form a thermoplastic composite with electrically and thermally conductive constituents. The method may include receiving a molten rod having a polymer composite core. The method may further include embedding the rod with at least one conductive wire. Embedding the rod with the at least one wire may include wrapping the at least one conductive wire around the rod and tensioning the wire thereby causing the wire to at least partially embed into the rod.
Method for assembling a rotor blade of a wind turbine
A method for assembling a rotor blade of a wind turbine: a) providing at least two different rotor blade modules that segment the rotor blade along a longitudinal direction thereof, wherein each rotor blade module has a sloped interface section that include a weldable thermoplastic resin and/or a weldable thermoset resin (M, b) providing a resistive element, c) arranging the rotor blade modules and the resistive element in such a way that sloped interface sections face each other and the resistive element is sandwiched between the sloped interface sections, d) energizing the resistive element to apply heat to a weldable thermoplastic resin and/or the weldable thermoset resin to melt or to soften it, and e) joining the sloped interface sections together at a joint by means of the molten or softened weldable thermoplastic resin and/or the weldable thermoset resin to form the rotor blade.
Method for bonding two fiber composite components with each other to form a fiber composite structure
A method for bonding two fiber composite components with each other to form a fiber composite structure includes integrating conductive fibers underneath a bonding surface of at least one of the two fiber composite components, each conductive fiber comprising a carbon fiber coated with an electrically insulating coating, the conductive fibers running along the bonding surface and protruding at least at their ends from the respective fiber composite component; arranging the two fiber composite components against each other at their respective bonding surfaces; passing an electric current through the conductive fibers by electrically contacting the conductive fibers at their protruding ends so that the respective fiber composite component is heated at the bonding surface to a curing temperature; and joining the two fiber composite components with each other at their bonding surfaces via secondary bonding, co-bonding and/or co-curing at the curing temperature, thereby forming the fiber composite structure.
