摘要:
The present invention relates to thermally conductive composite materials comprising an ultrahigh molecular weight (UHMW) polymer and a filler material in an amount of greater than about 60 wt % and uses thereof, including in fused deposition modeling and 3-D printing for making articles. The invention also relates to making the composite materials in solution. The composite materials possess desirable thermal conductivity and at least acceptable physical and/or mechanical properties.
摘要:
A positioning member (11) for a tubular (10) is formed using a prefabricated fiber-reinforced resin shell (1) positioned upon a surface of the tubular and bonded to provide a protrusion upon the surface of the tubular. In a disclosed method a fiber-reinforced resin shell (1) is secured to an external surface of a tubular (10) thereby enclosing a cavity between the shell (1) and the surface of the tubular (10); a bonding agent is introduced through inlet ports (5) in a surface of the fiber-reinforced resin shell (1) to fill a cavity between the shell (1) and the surface of the tubular (10), and the bonding agent is cured.
摘要:
Provided are methods of forming thermally conductive flexible bonds for use in electronic boards of unmanned spacecrafts and other types of aircraft. Also provided are methods of preparing adhesive materials to form these bonds including methods of preparing treated filler particles. In some aspects, an adhesive material includes filler particles having organofunctional groups, such as boron nitride particles treated in silane. These particles may be combined with a urethane modified epoxy to form the adhesive material. The weight ratio of the particles in the adhesive material may be about 40-60%. The adhesive material may be thermally cured using a temperature of less than 110°C to prevent damage to bonded electronic components. The cured adhesive may have a thermal conductivity of at least about 2 W/m K measured in vacuum and may have a glass transition temperature if less than -40°C.

摘要:
In a method for producing a textile piece of clothing with at least one abrasion-prevention zone provided with protector elements, the following steps are provided: 1) supplying a textile carrier layer (1), which can be stretched and is supplied in the form of a flexible tube (1) which is open at both ends and into which is introduced, prior to the coating material (5) being applied, a supporting element (2), by means of which the flexible tube (1) is pre-stretched and tensioned in a crease-free manner in the abrasion-prevention zones provided. 2) Supplying a pasty, curable coating material (5); 3) applying a multiplicity of portions of the coating material (5) to a surface of the carrier layer in order to form the protector elements, wherein the portions of coating material (5) are arranged on the surface such that the portions do not overlap and only part of the surface of the carrier layer is covered by the coating material (5). For this purpose, use is made of a metallic mould plate (10, 20), which contains a multiplicity of concave mould cavities (11, 21) for forming the protector elements (101), said mould cavities being filled with the pasty coating substance (5), and which is positioned, by way of the surface (12, 22) provided with the openings of the mould cavities (11, 21), on the flexible tube (1), which is supported by the supporting plate (2). 4) Curing the coating material (5), using temperature, to form a multiplicity of hard protector elements on the carrier layer.
