Description
Summary:Abstract The mechanical response and anti-extrusion characteristics of filled elastomers are examined in this paper. Both room-temperature and elevated-temperature uniaxial unconstrained compression and extrusion tests were carried out on hydrogenated nitriles (HNBRs) filled with carbon black and aramid fibres. The results suggest that fibre-filled HNBRs have a better resistance to extrusion over a range of extrusion gaps and temperatures. The level of extrusion resistance and the failure modes are related to the hardness and modulus of the material. It is shown that the current practice of using the hardness measured by conventional durometers to rank and/or select elastomers for specific applications may not be appropriate for elastomers with low concentration of fibres, as materials with nominally the same hardness have different resistances to extrusion and different compression moduli.
