Nowadays, most materials used to manufacture denture base are heat-cured PMMA, to overcome the low strength of this material, different methods were used to strengthen the denture base and enhanced their properties. This study investigated the effect of glass fiber woven powder kaolinite (Al2Si2O5 (OH) 4) to influence and strength of flexure. Acrylic and kaolinite powders were mixed together and mixed again with acrylic liquid to prepare hybrid composite samples. Woven glass fiber composite was prepared by inserting woven glass fiber between the two halves of the dough. PMMA reinforced by (0, 20) wt% of woven glass fibers or/and (0, 2, 5, 7) wt% of kaolinite powder to prepare eight experimental groups (n= 7). The fractured surface was an evaluation by scanning electron microscope (SEM). X-ray diffraction and Fourier transforminfrared spectra FTIR tests were used to examine kaolinite powder. Samples were tested with the use of a Charpy testing machine for impact test and Instron tensile testing machine for flexural test after storage in water for 10 days at 37 °C. The results showed woven glass fibers with clay powder together significantly increased the mechanical properties of PMMA.
