Automotive Ethernet cables

The ODU MINI-SNAP for Single Pair Ethernet (SPE) enables Ethernet connections via copper cables with a single twisted wire pair, while allowing for the voltage supply of terminal devices via PoDL (Power over Data Line). The simpler design of the new generation of connectors and the associated weight and space reduction are good for designers and developers in various areas. SPE is currently being introduced in new automotive generations, replacing CAN and other bus systems. In the future, communication, controls, and security functions will be managed uniformly via Ethernet.

Researchers develop efficient way to produce low-cost heat sinks

Researchers at the NUST MISIS university in Russia have found a way to reduce the cost of industrial and electronics heat-sink production by up to 10 times. Consequently, the heat sink product itself would also cost less. The proposed methods use rubbers and silicon carbide as components that are are mixed, pressed, and sintered.

Heat sinking in operating devices is a constant necessity, because overheating inevitably shortens the service life of expensive equipment. One of the most popular heat-sinking materials is graphite, because of its high resistance to high temperatures. However, this is an expensive material, since its production requires fairly "clean" conditions and exceptionally high-quality raw materials.

Scientists from the NUST MISIS Center for Composite Materials found a way to reduce the manufacturing cost of heat sinks significantly. Instead of graphite, they proposed using polymer materials, rubbers with silicon carbide inclusions. In this case, the mass of inclusions can even exceed that of the base material, depending on the desired strength, ductility, and heat resistance of the final material.

The production process is quite simple: The rubber mass is placed between two rollers that rotate toward each other at different speeds. Powdered silicon carbide is also added. The rollers mix the materials and pull a uniform mass. Next, the mass is placed in a special press form, where it is shaped into its desired shape. Finally, the pressed billet is sintered at 360 C.

"This is a very low-waste production," said Andrey Stepashkin, researcher at NUST MISIS Center for Composite Materials. "At the initial mixing stage, the mass is homogeneous, like plasticine or clay. Its remains can be immediately reused. In addition, both rubber and silicon carbide are inexpensive materials, if compared to graphite. The material obtained after sintering can withstand temperatures up to 300 C, it perfectly sinks heat, and almost does not conduct current. That is, it can be used both in industry and in electronics."

However, as noted by the scientists, their main achievement is not in creating this particular material, but in working out the mechanical properties (strength, crack resistance, plasticity, etc.) that can be created using the methods described. So, if silicon carbide is replaced with carbon fiber or, for example, boron nitride, such composites will find applications in other areas of technology, such as conductive components of electronics.
