TC28: Glass fibres for reinforcement and insulation

The Technical Committee on “Glass Fibers for Reinforcement and Insulation” was established in 2016 and officially approved by ICG in 2017. With an increase of the demand for protecting our climate, glass fibers are playing an increasingly important role, specifically in light vehicle, lightweight structure, renewable energy production, thermal insulation, etc., all of which contribute either to energy generation or to energy saving. Considering that fiber glass is far from equilibrium state and is greatly different from bulk glass in many ways, there are still many scientific problems to be addressed. There are varieties of glass fibers for a wide range of applications; however, at present, this committee focuses on the glass fibers for reinforcement and insulations. As science involved in glass fiber is a highly interdisciplinary field, this committee is composed of experts with different scientific and technological backgrounds. The committee aims at promoting scientific and technology exchanges and collaborations between academy and industry by organizing seminars/workshops/symposia. The committee will be an ideal platform for addressing current challenges in fiber glass science and technology. Furthermore, the committee will collaborate with other technical committees.

The working scope of this committee is summarised below. To achieve these goals, several immediate activities has been planned.

Goals:
This committee will examine all aspects of fibres excluding functional fibres. In particular it will include:

  1. fibre drawing
  2. reinforcement fibre
  3. insulating wool fibre
  4. fibre spinning

Specific areas of study will be:

Part A: Alternative raw materials; energy consumption and emission control
Part B: Viscosity & liquidus temperature; fiber spinnability; crystallisation; high temperature stability; sub Tg relaxation; fibre structure-property relations; structural heterogeneity and defects; surface chemistry; fibre surface interaction with sizing
Part C: Molecular dynamics simulation; fiber forming modelling; thermochemical modelling; composition design
Part D: Fiber strength; electrical properties; thermal conductivity; biopersistence; biosolubility; properties of composite; recylcing and recovery of fibres
