Patent number: 6805939Abstract: The areally extended composite material (1) contains fibers (20, 30) which are impregnated with plastic (21). The composite material comprises at least two arrays of parallel fiber cords (2, 3) which extend in different directions and which form a web, mesh or grid. The fiber cords can be bundle-like or band-like. The fibers (20) of a first array (2) are impregnated with substantially more plastic (21) than the fibers (30) of a second and possibly of a further array (3). The composite material (1) is stiff in the direction of the fibers of the first array and is flexible transversely to this direction. Openings advantageously exist between the fiber cords.Type: GrantFiled: November 28, 2000Date of Patent: October 19, 2004Assignee: Arova Schaffhausen AGInventors: Albert Maria Vodermayer, Wolfram Fritz.

Patent number: 6649264Abstract: A compound material including fibers which are embedded in a thermoplastic matrix has a free surface to be treated. The material has one or more capillary spaces extending between the fibers, which spaces are at least partly formed by communicating pores and which are open towards the free surface. An average diameter of the pores is greater than, equal to or not substantially less than the fiber diameter.Type: GrantFiled: September 18, 2000Date of Patent: November 18, 2003Assignees: Sulzer Innotec AG, Sika AGInventor: Albert Maria Vodermayer

Patent number: 6589377Abstract: The method for the manufacture of sections of fiber-plastic compound materials is carried out by means of at least one draw nozzle (10). In this nozzle, fibers (41) which are impregnated with flowable plastic (42) are formed under pressure to a product (41) with a predetermined cross-section and consolidated with the withdrawal of heat. The cross-sectional surface of the draw nozzle is periodically increased and decreased in time in its entire shape imparting region, with a value for the frequency of the oscillating cross-sectional surface being chosen less than 1 kHz, preferably less than 100 Hz.Type: GrantFiled: February 27, 2001Date of Patent: July 8, 2003Assignee: Arova Schaffhausen AGInventors: Albert Maria Vodermayer, Jens Kärger, Hans Erlach

Patent number: 6528611Abstract: The method for forming a finely divided polymerizate in the form of a dispersion (D) of particles (50, 51) for the purpose of manufacturing powder lacquers or fiber compound materials comprises two steps: 1) In a first step a solution (S1) of a polymer (P), which is dissolved in a first liquid (L1), is emulsified in a second liquid (L2). The polymer is not soluble in the second liquid. The first liquid has a lower boiling point than the second and it is soluble in the second only to a limited extent. Owing to the limited solubility the polymer remains dissolved in the droplets which arise during the emulsification. Under the influence of mechanical means—in particular of a high speed stirring apparatus (31, 32)—and by shear forces caused by the latter, droplets are formed, the average diameter (d) of which corresponds to one of the named uses and is preferably less than 0.03 mm.Type: GrantFiled: October 11, 2001Date of Patent: March 4, 2003Assignee: Arova Schaffhausen AGInventors: Albert Maria Vodermayer, Lothar Kuhnert

Patent number: 6482507Abstract: The fiber compound material contains at least one fiber component and at least two matrix components of different material classes which have different thermo-mechanical properties. In a manufacture of the compound material two matrix components can be liquefied and fiber filaments of the fiber component can be wetted by the liquefied matrix components. In this in the liquefied state the one matrix component is not soluble in the other. In a consolidation of the compound material one of the previously liquefied matrix components can be hardened out irreversibly to a duroplastic whereas the other of the previously liquefied matrix components remains meltable.Type: GrantFiled: April 6, 2001Date of Patent: November 19, 2002Assignee: Suizer Markets and Technology AGInventor: Albert Maria Vodermayer

Patent number: 6372294Abstract: The method for the manufacture of unidirectionally fiber reinforced thermoplastic bands comprises a pressure impregnation of a fiber strand in a bath with a dispersion of thermoplastic particles. Heat treatments for the drying of the strand and a melting on of the particles taken up by the strand follow the pressure impregnation. The strand is drawn through the bath at a predetermined draw-off speed about a plurality of deflection elements. The dispersion of the bath is largely held in a stationary state, namely through the supply of an infeed dispersion with a first particle concentration and through an initial setting of a second particle concentration in the bath: The infeed dispersion is fed in continuously or periodically, with the first particle concentration being held constant. A corresponding feeding in of a dispersion of higher particle concentrations as well as an additional amount of dispersing medium is possible.Type: GrantFiled: February 19, 1999Date of Patent: April 16, 2002Assignee: Sulzer Innotec AGInventors: Albert Maria Vodermayer, Jens Kärger, Stefan Kaufmann, Hans Erlach
