Pitch-based carbon fibre reinforced concretes

摘要

After short description of different fibres, the mechanical properties of carbon fibre reinforced concretes (CFEC) are characterized on the basis of the available test results and from authors' investigations executed in 1995. Basic problem in the design of this kind of composites is to ensure their high toughness creating conditions for multiple cracking of the matrix. Three different models are analysed and it is suggested that around 1.5
