Hearn and Singh investigated the electrostatic surface potentials on a consolidation press manufacturing of 55 mm MTV decoy flare pellets [37]. A typical voltage-trace for filling consolidation and removal of the pellet as is depicted in Figure 18.23. 

The usual commercial form of the element is powder, but it can be consolidated by pressing and resistance-sintering in a vacuum or hydrogen atmosphere. This process produces a compact shape in excess of 90 percent of the density of the metal. 

Metal-Matrix Composites. A metal-matrix composite (MMC) is comprised of a metal ahoy, less than 50% by volume that is reinforced by one or more constituents with a significantly higher elastic modulus. Reinforcement materials include carbides, oxides, graphite, borides, intermetahics or even polymeric products. These materials can be used in the form of whiskers, continuous or discontinuous fibers, or particles. Matrices can be made from metal ahoys of Mg, Al, Ti, Cu, Ni or Fe. In addition, intermetahic compounds such as titanium and nickel aluminides, Ti Al and Ni Al, respectively, are also used as a matrix material (58,59). P/M MMC can be formed by a variety of full-density hot consolidation processes, including hot pressing, hot isostatic pressing, extmsion, or forging. 

This is a material produced from the impregnation of glass fibre-mat (fibreglass, which is in the form of dry sheet, is commonly known as chopped stranded mat (CSM)) or rovings, with a liquid and unsaturated polyester resin, which thickens chemically to a dry sheet form. The total mix is sandwiched between polyethylene films and then roller-pressed to impregnate and consolidate it. 

A number of hides are then laid up in a box mould with a grooved base. The mould is then loaded into a press and heated with hot water to consolidate the... 

Fig. 7.11. The consolidation behavior in hot pressing of shock-modified AIN is found by Beauchamp and co-workers to be strongly influenced by shock modification [87B04].

The particle size of powder most often used for consolidation is —200 mesh (74 /xm sieve aperture), and the most widely practised method of consolidation is hot pressing in vacuo. 

The early promise of wide applications for beryllium has not materialised, despite improvements in purity and more efficient means of consolidation such as isostatic hot pressing, because of the metal s toxicity, brittleness and cost. It is now chiefly of interest in the specialised fields of aerospace and nuclear applications. BrushWellman is currently the sole commercial primary producer of beryllium metal in the West. 

Measurement of the punch and die forces plus the relative displacement of the punches can provide raw data which, when suitably processed and interpreted, facilitate the evaluation of many tableting parameters. Many of the workers first involved in instrumenting tablet presses concentrated on deriving relationships between the applied force (FA) and the porosity (E) of the consolidating mass.

The paper or paperboard manufacturing process is similar for all types of pulp. Pulp is spread out as extremely dilute slurry on a moving endless belt of filtering fabric. Water is removed by gravity and vacuum, and the resulting web of fibers is passed through presses to remove more water and consolidate the web. Paper and paperboard manufacturers use nearly identical processes, but paper-board is thicker (more than 0.3 mm). 

In building B-46, three separate operations are performed consolidation, demachlnlng, and cone swagglng. A rotary press Is used to consolidate A-5 explosive Into a grenade. To pick up the dust from this pressing operation, flexible rubber hoses (2.0 in.) are used. These lines are then connected to a stainless steel line that runs Into a wet collector. 

Compositions whose products of combustion produce energy in the infrared wave band are generally composed of magnesium powder, polytetrafluoroethylene (PTFE) and a binder. For efficient tactical utilization of the energy developed by the combustion process the composition is normally formed into pellets either by press consolidation or by press extrusion. The process being used at Longhorn at the time the electrostatic problem was encountered was press consolidation. The composition was being consolidated into a pellet...

Rozman etal. (1997b) reacted wood flour with maleic anhydride (MA) and mixed the modified wood with diallyl phthalate in the presence of BPO. The mixture was then hot-pressed to form well-consolidated boards. Reaction of the wood resulted in significant increases in MOE, MOR and impact toughness of boards, compared to composites made from unmodified wood flour. It was considered that the improved properties arose due to the grafting of the diallyl phthalate monomers on to the double bond of the covalently linked maleic moieties (Figure 6.5).
