摘要：

Six short organic fibres (polyamide, polyacrylonitrile, polypropylene, poly(vinyl alcohol), polyaramide and carbon) were used to reinforce cement based matrices. Two contents of reinforcement were investigated: one, variable in the range 0.35-1.40%, corresponding to a composite presenting the same cost as a glass fibre reinforced composite containing 2.5% glass fibres; and a second with a 6% content. Three-point flexure tests were performed and the indices of toughness were computed. The results indicate that the behaviour of the composites is brittle when the fibre content is low, except when polypropylene and poly(vinyl alcohol) fibres are used, or ductile for higher fibre contents, except when carbon and polyaramide fibres are used.
