Stable thermochromics polymer films with vanadium dioxide nanowires
A thermochromic device includes a film and a number of vanadium dioxide nanowires disposed within the film. The film is manufactured by hot extruding a material that includes a polymer and a plurality of vanadium dioxide nanowires on a drum to form a rough film.
Composite blade made by additive manufacturing
The present application relates to a blade of low pressure rectifier axial turbomachine. The blade can also be a rotor blade and/or a turbine blade. The blade includes a composite material with a matrix and a reinforcement that includes a mesh forming a three dimensional structure with a plurality of rods that describe a three-dimensional mesh based on polyhedrons. The three-dimensional structure extends over the majority of the thickness of the blade between the pressure side surface and the suction side surface and/or the majority of the length of the blade between the leading edge and the trailing edge. The rods of the reinforcement are bonded to each other and are distributed throughout the volume between the pressure side surface and the suction side surface of the blade. The rods form a three-dimensional mesh occupying the entire blade. The present application also relates to an iterative method for manufacturing a blade by additional layer manufacturing.
