Surface micro-texturing has been proven an effective way to reduce friction and wear for tribological applications. There is provided a low cost hot sintering method to apply micro-texturing on an advanced bearing polymer material. First, one face of the mold was micro-textured using a micro-casting method. Second, the cured Aromatic Thermosetting coPolyester (ATSP) powder was filled in the mold. Next, the filled mold was placed in a hot press for a hot sintering process. Finally, the textured bulk ATSP was cooled. The micro-textured ATSP bulk material was machined and compared with plain untextured material. The micro-textured material could effectively reduce friction at speeds lower than 2.46 m/s: 14% reduction in average.

A composite material structural member including a core member, composite material members, and at least one composite material sheet. The members are disposed around the core member and are adhered to each other to form a hollow space. The composite material sheet is disposed between the core member and the members so as to overlap the bonded portion between the members. The composite material sheet forms a hollow composited structure together with the members.

A ball joint having a ball pin and a housing. The ball pin together with the ball is accommodated in the housing to move in a rotational and pivotal manner. The ball is at least partially surrounded by a structural component. The structural component is essentially formed from a fiber-plastic composite structure and at least partially forms the housing.

A cylinder head cover and a method for producing a cylinder head cover are disclosed. The method for producing a cylinder head cover may include: providing at least two metallic bearing bridges including a respective through-opening for mounting at least one camshaft and aligning the respective through-opening of the at least two bearing bridges axially relative to one another; connecting at least one metallic connection element to the at least two bearing bridges in a fixed manner so that the at least two bearing bridges are fixed and aligned relative to one another; and at least partially overmoulding the at least two bearing bridges and the at least one connection element with a plastic material.

The invention provides a building block for a mechanical construction. The invention further provides a bearing, an actuator system, a housing, a hub, a mechanical connector and a gear box. The building block includes a first printed material being printed via an additive manufacturing process. The first printed material provides a framework of a second material different from the first printed material and at least partially embedded in the first printed material. The framework of the second material may be included in a hollow structure. Alternatively, at least a part of the framework of the second material may constitute at least a part of the inner wall of the hollow structure. The framework of the second material may be pre-fabricated or may also be generated via the additive manufacturing process. A benefit of this building block is that it allows an increase of strength while limiting the overall weight.

A radial-type magnetic encoder includes: an annular fixing member; and an annular plastic magnet attached to the annular fixing member. The annular fixing member includes the cylindrical portion, an outward flange portion extending outward in a radial direction from an edge of the cylindrical portion, and a sensor opposed portion bent from an edge of the outward flange portion and opposed to a magnetic sensor which detects rotation of the magnetic encoder, and the annular fixing member has a substantially U-shaped sectional shape along a plane including the radial direction and an axial direction. The annular plastic magnet has a shape that covers a front surface, a back surface, and an end edge of the sensor opposed portion, and an outer-diameter-side part of the outward flange portion.

A structure including a sliding layer that is formed on a roughened surface of a substrate and that has an excellent slidability, and a method for producing the structure. The sliding layer is formed of a powder of a carbon-composition-containing resin composition filled in at least concavities of roughness on the roughened surface.

A resin reservoir capable of storing the melted resin is provided in the pillar radially facing the pillar provided with the resin injection gate having a cross-sectional area larger than those of the other resin injection gates among a plurality of the pillars not provided with the resin injection gate or the pillar in the vicinity of the pillar facing the pillar provided with the resin injection gate having a cross-sectional area larger than those of the other resin injection gates among the plurality of the pillars not provided with the resin injection gate. A cross-sectional area of a communicating portion of the resin reservoir which communicates with the pillar is smaller than the smallest of cross-sectional areas of a plurality of the resin injection gates.

By using a forming die having a fixed die and a movable die moving along a parting surface on the fixed die and by moving the movable die along the parting surface, to press and hold a sintered part between the movable die and the fixed die, to form a cavity around the sintered part except parts which abut on the fixed die and the movable die by the forming die, and to fill the cavity with melted material which becomes an exterior part, so that the sintered part and the exterior part are integrated by insert molding.

A Corrosion Inhibiting Sprayable Thermoplastic (CIST) cover is formed by spraying melted CIST onto a mold, allowing the CIST to cure, removing the cured cover from the mold using a series of cuts if necessary, positioning the cover on a mechanical assembly whose shape is significantly identical to the mold, and fusing the cuts on the cover using heat to reform the cover on the mechanical assembly.
