Abstract:
A mass of metal fibers is disclosed. The metal fibers of the mass have a discrete length. The cross section of the metal fibers has two neighboring straight lined sides with an included angle of less than 90° and one or more irregularly shaped curved sides. The metal fibers of the mass have an average equivalent diameter of the fibers of less than 100 µm. The metal fibers of the mass have a standard deviation between fibers of the equivalent fiber diameter less than 25% of the equivalent fiber diameter.
Abstract:
Disclosed is a method of producing a wear resistant composite product including the steps of: contacting a first material with a second material, the first material having a liquidus temperature that is lower than the solidus temperature of the second material; heating the first . and second materials in an inert gas atmosphere at a pressure greater than standard atmospheric pressure to a temperature above the liquidus temperature of the said first material; maintaining the temperature of the first and second said materials above the liquidus temperature of the first material for a predetermined period of time so that the first material at least partially fuses to the second material.
Abstract:
Die Erfindung betrifft einen Verbundwerkstoff. Verbundwerkstoff ist aus mehreren zusammengefügten Scheiben aus Trägermaterial gebildet, wobei vorzugsweise in jede Scheibe mindestens eine Ausnehmung zur Aufnahme mindestens einer Faser (14) eingebracht ist. Erfindungsgemäss liegt in einem inneren Abschnitt (16) ein Verbund aus Trägermaterial und Faser (14) vor, wohingegen in einem äusseren Abschnitt (17) das Trägermaterial ausschliesslich vorliegt, wobei die Fasern (14) in den äusseren Abschnitt (17), in welchem das Trägermaterial ausschliesslich vorliegt, zur festigkeitsoptimierenden Verzahnung von innerem Abschnitt (16) und äusserem Abschnitt (17) unterschiedlich weit hineinragen.
Abstract:
A golf club head insert (1) is disclosed comprising a fiber-reinforced metal matrix (2). Also disclosed is a golf club comprising a main body member (11), a strike face (5) of a fiber-reinforced metal matrix insert (2), and means for joining the fiber-reinforced metal matrix composite insert to the main body member.
Abstract:
A selectively reinforced component (10) comprises a metal body (12) with at least one metal matrix composite insert (14) embedded in a first surface (18) of the metal body (12), with at least one weld bonding an outer surface of the metal matrix composite insert (14) to the metal body (12). The selectively reinforced component (10) is formed by introducing the or each metal matrix composite insert (14) into a recess (16) inthe first surface (18) of the metal body (12), before forming the at least one weld to bond the outer surface of the metal matrix composite insert (14) to an opposing inner peripheral surface of the recess (16).
Abstract:
L'invention concerne notamment un procédé d'imprégnation d'une texture fibreuse de forme creuse, le procédé comprenant au moins les étapes suivantes : - introduire une première suspension (10) comprenant une première poudre de particules solides en matériau céramique ou en carbone dans un volume intérieur (2) délimité par une face interne (la) d'une texture fibreuse (1) de forme creuse placée dans un moule, une face externe (lb) de la texture fibreuse (1) étant présente en regard d'une paroi (3) du moule, et - imprégner par action de la force centrifuge la texture fibreuse (1) par la première suspension (10) par mise en rotation du moule sur lui-même en faisant varier la vitesse de rotation du moule durant l'imprégnation de la texture (1) par la première suspension (10).
Abstract:
Composite bodies and methods for producing such composite bodies having discontinuous graphite preforms and at least one silicon-bearing metal alloy infiltrant are described. The metal alloy is preferably comprised of aluminum, copper, or magnesium, or combinations thereof. Certain embodiments provide at least one aluminum alloy having from about 5% silicon to about 30% silicon and from about 11% to about 13% silicon, as an alloying element. Certain embodiments provide an aluminum-silicon eutectic composition having about 12.5% silicon. Embodiments of the invention provide composite materials be "tuned" to more closely match thermal expansion characteristics of a number of semiconductor and integrated circuit materials such as, but not limited to, silicon, alumina, aluminum nitride, gallium nitride, and gallium arsenide while also providing high thermal conductivity. Embodiments of the present invention are especially suited for use as a heat sink, a heat spreader, or both.
Abstract:
Short fiber-reinforced composite including a matrix material; and, a minor percentage of short-fibers having an altered fiber morphology, such a fiber morphology being wherein selected portions of said short-fiber are greater in cross-sectional diameter than the cross-sectional diameter of said fiber at other portions of said fiber, such cross-sectional diameter being perpendicular across said fiber's main axis. Such fibers can be shaped as bone-shaped or dumbbell-shaped in structure.
