A lecture given by Peter Jenkins of the University of Strathclyde, Department of Mechanical and Aerospace Engineering, for the 2016 Literature Review Prize of the Institute of Materials, Minerals and Mining (London). 

The strength loss of glass fibres (GFs) following exposure to elevated temperatures is a long-established phenomenon, yet the mechanism or mechanisms responsible for the strength decrease are not fully understood, aside from acknowledgement that surface flaws must become more severe by some means. As disposal of GF-based composite materials by landfill has become untenable in many regions, interest in composite recyclability has increased. Separation of GFs from thermosetting polymers generally requires the use of high temperatures, which produces very weak fibres with minimal commercial value. In this context, an understanding of the strength loss mechanisms is of importance in terms of efforts to mitigate fibre damage or to recover the strength of previously heated fibres. In addition to fibre strength loss, numerous other physical and chemical changes to heat treated or recycled GF have been described in the literature.
The Materials Literature Review Prize of IOM3 aims to encourage the preparation of definitive, critical reviews of the literature by students as an essential part of study for a higher degree in the materials field, and subsequently make the best of these available to a wider readership. The prize is administered by the Editorial Board of MST (the journal Materials Science and Technology).

Open to any postgraduate student studying in the UK or internationally, the prize carries a cash award, in line with other IOM3 prizes for papers. A winning entry and two runner-up prizes are awarded each year, and all entries are considered for publication in the journal subject to acceptance following peer-review.
