The needed of high performance fibres in technical textile industry is higher from timeto-time since it can replace the heavy metal properties demand. One of popular fibres beside aramid and carbon is called ultrahigh molecular weight polyethylene (UHMWPE) which the high performance polyethylene in numerous research have been observing. Based on some studies, UHMWPE has low adhesion to polymer matrix. Therefore, in this research, to improve the adhesion between UHMWPE fibre and polymer matrix,

The interlaminar shear strength (ILSS) and mechanical properties of the composite were investigated, in comparison with those of the composite without any fillers. In addition, the surface morphology and structure of UHMWPE/HDPE composite filled with TEOS were studied by SEM and EDS. The results showed the ILSS with TEOS improved only 15% from those without fillers but the shear modulus was twice higher. By SEM observation, it showed that UHMWPE/HDPE composite surface was observed with some particles attached. Although there was no chemical interaction between TEOS and UHMWPE/HDPE chains, TEOS has some interaction with UHMWPE molecular chains according to the results of EDS. The TEOS coatings have an effect on the adhesion may be associated with the roughened surface of the composite and upon intermolecular interaction.
