Braking systems are undoubtedly the most important component for road safety, since it determines the total or partial stop of a vehicle and, therefore, guarantees the physical integrity of passengers. Normally, the front brake discs and the remaining percentage absorb 70% of the kinetic energy produced within a vehicle by the rear brake discs, which tend to have the form of a drum brake. These systems benefit from friction to stop a moving vehicle, under the umbrella of hydraulic pressure that pushes the brake pads against the iron-cast disk. In this document, concepts of famous authors around the world on analysis and evaluation of brake discs are provided, which are carried out using a descriptive methodology and an estimation of the characteristics of the brake disc. The review is carried out in computer assisted design through several existing CAD software in the industry, as the main methodology applied to the development of certain research projects, where different geometric characteristics of the brake discs are considered, as well as problems related to wear and corrosion. This research project has shown that it is vital to incorporate existing computer assisted design software to predict performance, improve components and optimize the functionality of the brake system. In this way, road traffic safety and systems efficiency are achieved, which are a matter of great importance for the industry. It is vital to analyze brake systems through Finite Element Analysis (FEA), with the intention of achieving a broader vision of its performance, since the information collected reveals that the geometric characteristics of the brake and cooling ducts influence the heat dissipation. It depends on the form, the type of material and the application, the heat generated between the pad and the brake. Therefore, the heat is dissipated rapidly according to the analysis performed mathematically by the researchers, which are compared with the made in computer assisted design software.

This chapter describes a summary of the main tribological achievements carried out in TEKNIKER during the last 37 years. It covers the description of commercial and newly developed tribological test benches and case studies for a wide variety of applications. The examples refer to different tribological characterization tools for material selection (e.g., composition, surface treatments, lubricants). It makes emphasis in the failure mechanisms (pitting, scuffing, abrasion, adhesion, thermal fatigue, tribocorrosion, etc.) and friction simulation of a wide range of materials (seals, textiles, steels, cast iron, light alloys, ceramic, composites), tribological systems (mechanical components, biomaterials, tribolubrication), and environments (vacuum, ultrahigh vacuum, low or high temperature, and corrosive). A huge range of new testing equipment and protocols have been developed to simulate the mentioned failure mechanisms and working environments. This knowledge will make possible, in the future, to simulate at laboratory a still wider list of tribological systems and develop new standards. Tribology will help to implement materials solutions into energy and resource efficient products and process, to reduce carbon footprint.2 with more than 250 scientific contributions in congresses, journals, and books and 3 patents. It has been active in several international working groups and associations, in some of them, acting as Spanish representative:• The COST 516 about tribology (1995)(1996)(1997)(1998)(1999)(2000) • The COST 532 about tribotechnology of engines and transmissions

“…Advances in adhesive technologies in the last decade have led to a significant increase in the use of aluminium and composite materials in lightweight structures, especially in the automotive and aerospace sectors, which are not always easy to join by other technologies, e.g. riveting, brazing and soldering [ 1 – 3 ]. Epoxy adhesive systems based on two component thixotropic pastes are used for high strength joints in a wide range of structural components of metal, glass, plastic and ceramic to each other.…”

Torsional shear strength of steel joined with high performance aerospace adhesives at cryogenic and elevated temperatures

et al. 2018

Pure torsional shear tests of joints glued with two different aerospace grade adhesives were performed using a specifically designed and constructed torsional shear test equipment. The developed test equipment allows for measuring of pure torsional shear strength under cryogenic and at elevated temperature conditions. The adhesives Hysol EA 9321 and 3M Scotch-Weld EC-9323-2 B/A were used to join steel torsional shear test specimens. Torsional shear tests were performed from -180°C to 150°C. In addition torsional shear fatigue tests were also performed at various loads and the effect of cryogenic aging (cyclic cooling and warming) on the torsional strength of the joints was investigated. The results showed that both sets of adhesive joints achieved three times higher torsional shear strength at -180°C compared to room temperature.
