Abstract
A planar element is disclosed for use in a papermaking system. The planar element is suitable for use as a doctor blade or a top plate and includes a three-dimensional composite structure including elongated elements extending in at least three orthogonal directions, and a resin in which the three-dimensional composite structure is embedded.
Claims33
A planar element for use in a papermaking system, said planar element being suitable for use as a doctor blade or a top plate, said planar element comprising:
- a three-dimensional composite structure including elongated elements extending in at least three orthogonal directions;
- and
- a resin in which the three-dimensional composite structure is embedded.
A doctor blade for use in a papermaking system, said doctor blade comprising:
- a three-dimensional fabric composite structure including elongated elements extending in at least three orthogonal directions, at least some of the elongated elements being woven together;
- and
- a resin in which the three-dimensional composite structure is embedded.
A method of forming a doctor blade, said method comprising the steps of:
- forming a three dimensional fabric structure that includes elongated elements that extend at least in part, in each of three mutually orthogonal elongated directions;
- and
- embedding the three-dimensional fabric structure with a resin.
