Aramid cores are made from paper (typically 1.5 mil in thickness) comprising w-aramid floe and fibrids, similar to the papers used in electrical applications discussed in the previous section. Adhesive node lines are printed on paper sheets that are then stacked, pressed, and heated to cure the adhesive. The resulting block is expanded. The adhesive-free areas form the hexagonal cells of the honeycomb configuration. The core is dipped several times in an epoxy or phenolic resin solution until the desired density and mechanical property levels are reached. The core is then cut into slices of the desired thickness. Face sheets are glued to each side of the core. The most common face sheet today is a composite of carbon fiber and epoxy resin. 

Recently, high-speed rotation-induced wood-dowel welding, which is an adhesive-free wood joining technique, has been developed [1-3] and represents one of the innovative aspects of wood bonding. The process consists in insertion...

When choosing an air filter medium, it may be preferable to select one that has been tested using a test dust of non-adhesive free running aluminium oxide particles and proven to have collected this dust without unloading under vibration. 

Connections made with insulating adhesives free of fillers are electrically conductive if the partners are in contact with each other in adhesive no thicker than the surface roughness (< 10 pm). In principle the process is very similar to that of anisotropic adhesive gluing. The glue is applied by a dispenser or by print application of a paste. The electrically nonconductive adhesive can be applied allover across multiple connections. This implies low requirements for the process as such and therefore good affinity for fine-pitch applications. Once the partners to be joined have been positioned, the adhesive cures under pressure and temperature within a matter of seconds.
