  • Abrasive wear performance of various polyamides 

    Rajesh, J John; Bijwe, J; Tewari, U S (2002)
    Polyamides (PAs) form a major class of tribo-polymers used in almost all types of wear situations. They excel most of the engineering polymers especially in the case of abrasive wear performance. Since methylene (---CH2---) ...
  • Effect of impinging velocity on the erosive wear behaviour of polyamides 

    Rajesh, J John; Bijwe, J; Venkataraman, B; Tewari, U S (2004)
    Various parameters, such as type, size and velocity of erodent and impact angle, are important for the erosive wear behaviour of materials. In this work, the erosive wear behaviour of various polyamides (PAs), viz. PA 6, ...
  • Erosive wear bahavious of various polyamides 

    J John, Rajesh; Bijwe, Jayashree; Tewari, U S; Venkataraman, B (2001)
    A series of polyamides (PAs), namely, PA 6, PA 66, PA 66/610, PA 11, PA 12 and aromatic PA (brittle, hard and amorphous) was selected for investigating the effect of chemical structure and hence, mechanical properties on ...
  • Influence of solid lubricants and fibre reinforcement on wear behaviour of polyethersulphone 

    Bijwe, Jayashree; Rajesh, J John; Jeyakumar, A; Ghosh, A; Tewari, U S (2000)
    Polyethersulphone (PES), is an amorphous, brittle and high temperature engineering thermoplastic. Two composites of PES containing short glass fibres (GF) and solid lubricants viz. PTFE and MoS2; and two composites containing ...
  • On the abrasive wear of some polyimides and their composites 

    Tewari, U S; Bijwe, J (1991)
    The tribological properties are not intrinsic material properties; they depend on the experimental conditions. Composites that are very suitable for one type of application may not be useful for others. With this view, it ...
  • Solid particle erosion behaviour of various polyaryletherketone composites 

    Harsha, A P; Tewari, U S; Venkatraman, B (2003)
    The solid particle erosion behaviour of various polyaryletherketones (PAEKs) and their short fibre reinforced composites has been characterised. The erosion rates (ERs) of these composites have been evaluated at different ...
  • Solid particle erosion of carbon fibre– and glass fibre–epoxy composites 

    Tewari, U S; Harsha, A P; Häger, A M; Friedrich, K (2003)
    The solid particle erosion behaviour of unidirectional carbon and glass fibre reinforced epoxy composites has been characterized. The erosive wear of these composites have been evaluated at different impingement angles ...
  • Solid particle erosion of unidirectional carbon fibre reinforced polyetheretherketone composites 

    Tewari, U S; Harsha, A P; Häger, A M; Friedrich, K (2002)
    The solid particle erosion behaviour of unidirectional carbon fibre (CF) reinforced polyetheretherketone (PEEK) composites has been characterised. The erosion rates of these composites have been evaluated at different ...
  • Studies on abrasive wear of carbon fibre (short) reinforced polyamide composites 

    Tewari, U S; Bijwe, J; Mathur, J N; Sharma, Indu (1992)
    This paper reports the results of the abrasive wear investigations of various composites of polyamide (nylon 6,6) reinforced with increasing amounts of carbon fibre against various abrasive papers under dry conditions. The ...
  • Three-body abrasive wear behaviour of polyaryletherketone composites 

    Harsha, A P; Tewari, U S; Venkatraman, B (2003)
    An experimental investigation was carried out to study the effect of reinforcement fibres, solid lubricants, mass of abrasives and load in three-body abrasive wear situations on various polyaryletherketone (PAEK) matrix. ...
  • Tribo performance of polyaryletherketone composites 

    Harsha, A P; Tewari, U S (2002)
    The mechanical and tribological properties of various injection-moulded polyaryletherketones (PAEKs) and their composites are presented in this paper. The mechanical properties studied were tensile strength, tensile modulus, ...
  • Two-body and three-body abrasive wear behaviour of polyaryletherketone composites 

    Harsha, A P; Tewari, U S (2003)
    Single and multipass two-body and three-body abrasive wear behaviour of various polyaryletherketone composites have been carried out by using a pin-on-disc machine and a rubber wheel abrasion test (RWAT) rig. Abrasive wear ...
