“…In order to increase the wettability between the interfaces, the most preferred method is to alloy the copper. According to the literature, titanium is the most prominent as an alloying carbide forming element [34][35][36][37][38][39][40]. Apart from this, it has been observed that Cr and Si elements are also used [32,41,42].…”

“…The carbon preforms used in reviewed studies can be broadly divided into two categories, carbon/carbon preforms [37,38,51] and carbon preforms [48][49][50]53]. Although most of them are produced from carbon fibers [34,35,37,44,50,51], it has been observed in some cases that the starting material was carbon powder [47,52,53]. Apart from this, preforms produced with 3D printing [36] are slowly starting to be used by researchers also.…”

“…Long [41] and short fibers [38,45] or continuous fibers [34] have been used in different studies. Moreover, these preforms were preferred to be knitted in some studies [34,35,51] and non-woven in others [37][38][39][40].…”

The liquid metal infiltration of carbon preformed with copper and its alloys is already an established and well-known process. It is extensively used by the electronic industry to produce heat sinks of power electronics and electric contacts and sliding electric contacts. The advantage of the process is its ability to produce near net shape components with high volume fractions of carbon at a relatively low price. The process is carried out in a vacuum and with low applied pressure. However, a strong dependence on the temperature of infiltration and its precise control is significant for the sound final product. For certain pair carbon matrix–copper alloys, different results could be obtained according to the infiltration temperature. If the temperature is too low, the solidification may occur prior to complete infiltration (high final porosity). When the temperature is too high, undesirable reactions may occur at the fiber–matrix interface (e.g., corrosive carbides). Therefore, there are still a lot of scientific papers pushing this technology to new directions and over old limits. Publications inside scientific journals within this field deal with composite materials for sliding electrical contact and electrical contact materials, sealing materials, parts of brake disks, pantograph strips for high-speed railways, other electric and mechanical applications and even for wall surface shields in future fusion devices. The present paper reviews used carbon preforms, copper alloys, technological parameters, properties of prepared composites prepared via infiltration during the last 12 years. It can be stated that 1/3 of the papers were published within the last 3 years. Moreover, renewed interest in this low-cost technique could be expected within the next few years due to climate programs and increasing prices of the energy resources.
