...-impregnated thermoplastics, and true thermoplastics. It describes the processing methods of thermoplastic composites, including weaving, seaming, autoclaving, preconsolidation, roll consolidation, roll forming/pultruding, thermoforming, press forming, hydroforming, and diaphragm forming. The article provides...

... loose powder and extruding a preconsolidated billet. Extruding loose powder requires a specialized container with a nose plug designed to protect the evacuation stem on the container from rupturing prior to entering the extrusion die. Extrusion ratios used for direct extrusion of powder are at least 7...

..., in-house manufacture of thermoplastic molding compounds is becoming increasingly common. In molding of continuously reinforced composites, results are likely improved if preconsolidated composite panels are used rather than stacks of individual prepregs, since the time allowed for consolidation in most...

.... Alternatively, preconsolidated aluminum-beryllium and beryllium is extruded to two-dimensional NNS with commercially acceptable tolerances. Mechanical properties of extrusions along the direction of metal flow are superior to those for powder consolidated using VHP and HIP. Billets for extrusion...

... mechanical properties. Initially, the P/M version was developed for use in the as-hot isostatically pressed (i.e., no hot working) plus heat treated condition. Although as-hot isostatically pressed René 95 is in current use, most René 95 production involves extrusion of preconsolidated powder followed...

.... A vertical force is applied to the top by means of a weight hanger. This force causes a vertical pressure, σ t , in the material. By means of a special wrench, a number of oscillating twists are now applied to the cover. This preconsolidates the powder and ensures a uniform specimen. The twisting load...
