• Compression stress relaxation in carbon black reinforced HNBR at low temperatures 

      Akulichev, Anton; Alcock, Benjamin; Echtermeyer, Andreas (Peer reviewed; Journal article, 2017)
      Findings of a study of stress relaxation behaviour of hydrogenated nitrile butadiene rubber (HNBR) at nominal compressive strains up to 0.4 and temperatures above and below the glass transition temperature Tg are reported. ...
    • HNBR elastomer composite with zero thermal contraction over a range of temperatures 

      Akulichev, Anton; Alcock, Benjamin; Protasov, Andrey; Markin, Pavel; Echtermeyer, Andreas (Peer reviewed; Journal article, 2019)
      Elastomers such as hydrogenated nitrile butadiene rubber (HNBR) are known to have inferior dimensional stability upon temperature changes compared to metallic materials. This can result in thermal contraction mismatches ...
    • Long-term ISO 23936-2 sweet oil ageing of HNBR 

      Akulichev, Anton; Alcock, Benjamin; Krauklis, Andrey; Tiwari, Avinash; Echtermeyer, Andreas (Peer reviewed; Journal article, 2021)
      A hydrogenated nitrile butadiene rubber (HNBR) compound is subjected to ageing in a simulated oil and gas environment in accordance with ISO 23936-2 standard at two elevated temperatures (130 °C and 150 °C) for a period ...
    • Zero Stress Aging of Glass and Carbon Fibers in Water and Oil—Strength Reduction Explained by Dissolution Kinetics 

      Echtermeyer, Andreas; Krauklis, Andrey; Gagani, Abedin; Sæter, Erik (Peer reviewed; Journal article, 2019)
      Understanding the strength degradation of glass and carbon fibers due to exposure to liquids over time is important for structural applications. A model has been developed for glass fibers that links the strength reduction ...
