Abstract
The aim of the paper is to investigate interphase interactions on the fibre-melt interface boundary during metallization of boron fibres by aluminium.
Using methods of selective etching and weighing it has been stated that chemical interaction of boron fibres with the aluminium melt develops in 2 stages: firstly - boron solution in liquid aluminium occurs, secondly - formation of chemical compounds AlB2, AlB12 on the interface boundary.
Mechanical tests and fractographic analysis have stated that if the fibre material is soluted in the melt then fibre strength raises due to the lower influence of surface defects; the appearance of aluminium borides on the interface boundary is followed by a decrease in the initial fibre strength.
