R-TECH Materials received a request for testing of a basalt fibre to qualify the validity of the customer’s internal testing. As part of this, R-TECH were requested to carry out a number of tests according to the client’s internal procedures. These tests included the following:

  • Loss on ignition
  • Tensile strength
  • Moisture content
  • Fibre diameter
  • Linear density of the fibre
  • weight loss in sodium hydroxide
  • weight loss in sodium carbonate
  • weight loss in Sulphuric acid

Our experience in both wet chemistry techniques, along with mechanical testing and specimen manufacture, ensured that we were able to carry out a high quality test programme.
