Introduction Silicon-based photodetectors are the devices that convert optical signals into electrical signals, and they have unique advantages compared with the systems based on other materials because of the semiconductor material silicon, as the leading photoelectric materials, which have abundant resources, low cost, environment-friendly, mature processing technology and other outstanding properties [1,2].
Common traditional semiconductor materials include cadmium sulfide (CdS) [3], lead sulfide (PbS) [4], indium antimonide (InSb) [5,6], indium arsenide (InAs) [7], mercury telluride (HgCdTe) [8], etc.

The manufacturing technologies are fully developed and raw materials are cheap.
Standard epoxy or polyester materials are capable for temperatures up to 150 °C before they start to degrade.
The complex processing and the high priced raw materials make them unattractive for series parts.
Inert and active filler materials minimize this issue, hence fiber reinforcement is an option.
Fig. 9: Volume of wear of the tested friction materials after pin on disc measurement Further tribological investigations will concentrate on that temperature window, combined with different fiber architecture and filler materials.
