    Abstract: A mixed PTFE powder according to the present invention is prepared by the steps of preparing a PTFE mixed dispersion by dispersing MoS2, Al2O3, and Al(OH)3 in a PTFE emulsion; dehydrating the PTFE mixed dispersion by adding Na2CO3 into the PTFE mixed dispersion to form a cake type compound; preparing an ingot by drying the cake type compound for about 16 to 24 hours at the temperature of about 120 to 190° C.; and pulverizing the ingot in a 30-35 mesh vibrating net. An HDME PTFE yarn according to the present invention is prepared by the steps of preparing the mixed PTFE powder; adding kerosene of about 18 to 25 wt. % as solvent to the mixed PTFE powder and maintaining the resultant for about 40 to 50 hours at the temperature of about 30 to 50° C.; extruding the resulting mixed PTFE into the form of rod at about 70 to 90° C.; calendering the rod into the form of sheet at about 100 to 150° C., the width of the sheet being about 100 to 300 mm and the thickness about 0.3 to 0.7 mm; folding the sheet to become a three layered sheet and passing through the three layered sheet in an oven of about 250 to 270° C. at a speed of about 10 to 40 cm per second; and drawing the three-layered sheet at the temperature of about 450 to 500° C. at the speed of about 30 to 100 cm/s and the drawing ratio of about 200 to 600%.

    Abstract: The invention relates to a method for producing a reinforcement rod (2) from a fibrous composite material consisting of continuous mineral fibers (5, 23, 35) and at least one resin (7, 25), at least one portion of the mineral fibers (5, 23) being mixed with a resin-curing agent mixture, the mineral fibers (5, 23) that have been mixed with the resin-curing agent mixture and, optionally, resin-free mineral fibers (35) subsequently being brought together to form a rod, and the resin (7, 25) being cured. A mixture of at least one resin (7, 25) and at least two different curing agents is used as said resin-curing agent mixture, the two curing agents forming reactive species under different conditions for curing the resin (7, 25) such that the reactive species are available for the curing process at different times.
