The influence of sol-gel modified fibres content on the melt flow index (MFI) and water absorption of a linear low density polyethylene was investigated. The fibres were modified with silica xerogel prepared by the sol-gel polymerization of tetraethylorthosilicate (TEOS) under hydrolytic conditions using acid catalysis. Alkali pre-treatment was used for some variants and some composite samples were prepared by adding maleic anhydride grafted polyethylene (MA-g-PE). It was found out that melt flow index increases using sol-gel method for hemp fibres modification with fibres content in composite 40 and 50 wt%. Composite with fibres modified by sol-gel method content 40 wt% water absorption were evaluated in a range from 8.5 to 16.32%, but for composites with 50 wt% - 12.12%.
