A systematic study of the effect of concentration of maleated polypropylene MAPP, dicumyl peroxide DCP, polyisobutadiene isocyanate PBNCO and fiber content on the mechanical properties of ASspen-PP composite was undertaken with the objective to protect or increase the impact strength without losing tensile strength reinforcement. Using STAGRAPHIC Plus, the central composite design it was possible to determine the optimum concentration of additives and to maximiye both the impact as well as tensile properties well above that of pure polypropylene.

Systematicky byl studován vliv koncentrace maleovaného polypropylenu, dikumyl peroxidu, polyisobutylen-isokyanátu a obsahu vláken na mechanické vlastnosti kompozitů osika-polypropylen s cílem udržet nebo zvýšit jejich houževnatost bez ztráty ztužení. S použitím STAGRAPHIC Plus – the central composite design bylo možné určit optimální koncentrace aditiv a maximalizovat současně houževnatost a tahové vlastnosti, oboje nad vlastnosti čistého polypropylenu.
