This article is focused on the utilization of elementary mathematical model for description of mechanical behaviour of composites materials reinforced by fibres of Ensete Ventricosium under tension loading. Elementary mathematical model was derived for unidirectional fibres oriented in the direction of tension loading and it was experimentally verified. As a matrix it was used a two-component resin Gluepox Rapid and as a reinforcement they were used fibres of Ensete Ventricosum. Experimental samples with different volume fibres ratio contained 40, 60, 80, 100, 120 and 140 fibres were tested on tensile equipment MP Test – 5.050. In this study the elementary mathematical model was utilized for description of dependency between modulus of elasticity, rupture stress and volume fibres ratio. From this research follows that data determined from derived elementary mathematical model are significant (on the level of significance 0.05) with experimentally determined data. This derived elementary mathematical model can be used as background for further research related to the modelling of mechanical behaviour of composites reinforced by fibres.
