The Effect of Interface Structure on the Strength of Fibrous Composite Materials

Metal matrix composite fabrication methods

“…Therefore, during plasma spraying of the material, the particles interact strongly with the plasma and surrounding media. Thus, for example, when the aluminium alloy ADI is sprayed in air, the content of gas admixtures in it (% by weight) grows considerably: hydrogen from 0.003 to 0.02, nitrogen from 0.002 to 0.01 and oxygen from 0.002 to 0.009 [3]. Studies of the properties exhibited by the aluminium alloys used as matrices in MMCMs fabricated by plasma spraying followed by hot compaction showed that their strength and yield point is much higher than with standard aluminium alloys, whereas their relative extension during rupture is very close to that shown by cast aluminium alloys (Table 3.1).…”

“…The fabrication of blanks consisting of isolated fibres, fibre bundles or cloths can also be accomplished through infiltration by melted matrix metal [3], and chemical or electrochemical deposition [4].…”

Material for Radiation Protection. Stretching-reducing of the Powder Composition “Al-B”

“…Pressing is carried out at a temperature T = 500 ÷ 580 ∘ C, pressure of 30 MPa and the holding time of 120 s in molds, or autoclaves. This technology is described in works [4][5][6][7]. An example of the microstructure of the starting FCM is shown in Fig.1.…”
