Carbon fibre reinforced polymer/titanium stacks (CFRP/Ti6Al4V) are employed in aeronautics due to their excellent weight-to-strength ratio and corrosion properties. However, these same material properties present challenges for hole making which cannot be solved using conventional water-based metalw ...

ǂThe ǂimpact of airborne emissions from coolants and lubricants on machining costs
Iñigo Rodriguez, Pedro J. Arrazola, Franci Pušavec
Izvirni znanstveni članek
Oznake: safety;sustainable machining;productivity;
A novel aerosol evaluation cell was employed to measure particle number and mass concentration, with a size distribution from nano to micro scale. Different cooling/lubrication and airflow extraction scenarios were tested on a CFRP/Ti6Al4V case study, and the particle concentrations were measured to ...

Pri razvoju mehansko in temperaturno obremenjenih strojnih elementov je ključno napovedati, kako se bo material odzval na tovrstne obremenitve. V prvem delu zaključne naloge je pregled literature na področju lezenja in relaksacije ter modeliranja napetostnodeformacijskih stanj. Namen diplomske nalog ...

Carbon Fibre Reinforced Polymers (CFRPs) and Ti6Al4V titanium alloys are widely used for structural applications in aeronautics due to their superior strength-to-weight ratio and corrosion properties. These materials are often combined to create hybrid CFRP/Ti6Al4V stacks. Composite/metal stacks are ...
