FIELD: manufacturing technology.
SUBSTANCE: invention relates to a fibre-reinforced plastic structure (composites), articles made from fibre-reinforced plastic structure described in this invention, and use of such articles. Composite material comprises reinforcing fibres and a matrix made of matrix material surrounding said fibre, wherein matrix material contains furan resin and, optionally, epoxy resin and reinforcing fibres contain polyphenylene sulphide. Composite material is used as material for pipes, tubes and/or containers, wherein said pipes, tubes and/or containers are in contact with alkaline liquids.
EFFECT: composite material is resistant to NaOH and other alkaline fluids at temperatures over 60 °C.
