In recent years, both industrial and academic world are focussing their attention towards the development of sustainable composites, reinforced with fibres. In particular, among the fibres that can be used as reinforcement, the uniaxial glass fiber ones represent the most interesting for their properties. The aim of this work is to illustrate the results of friction and wear behaviour of uniaxial glass fibers with silicon carbide, aluminium oxide and graphite as the fillers. Moreover, its main manufacturing technologies have been described. The major component of these hybrid composite is uniaxial glass fibre with Epoxy LY556 (Resin). Hardener HY951 is used for hardening and support. Resin + Hardener are mixed in the ratio 10:1 and the mixture made up is called Matrix. Test materials of glass Fibre with varying compositions of 15% Al2O3 + SiC and glass fibre with varying compositions of 15% Graphite + SiC have been prepared by applying the matrix on glass cloth which is wrapped around the mandrel. The samples were tested in a pin-on-disc machine to determine the friction and wear losses. Further, the samples were tested on a pin-on-disc machine and frictional characteristics were monitored by varying speed and loads. Thus, the friction and wear characteristics have also been found out for the two specimens. From the experimental test results, it is observed that Al2O3 +Sic exihibits lower wear loss than SiC + Graphite under dry sliding conditions. Based on the observations, this hybrid composite are recommended to the manufacturing of the aircraft structures.

In this study, bearing bushes made of polyetheretherketone (PEEK), 30 wt % carbon fibre reinforced PEEK, 30 wt % glass fibre reinforced PEEK, each 10 wt % of PTFE, graphite and carbon fibre modified PEEK were investigated on a purpose built pin joint test rig. The unlubricated friction and wear behaviour was assessed in sliding contact with a 300M shaft, subjected to a nominal pressure of 93 MPa, articulating sliding speed of 45 °/s. The worn surface and the subsurface layer were studied using optical profilometry and scanning electron microscopy (SEM). Due to thermal sensitivity of PEEK composites, friction energy and temperature rise were analysed for determining the friction and wear mechanism. The bush made of PTFE, graphite and carbon fibre (each 10 wt %) modified PEEK presented the best performance for friction coefficient, wear loss, friction energy and temperature rise. Current work demonstrated that reinforcement modified PEEK composite possesses desirable properties to perform as a load bearing bush in certain tribological applications.
