Abstract:

The micro structure and main properties of unsaturated polyester modified with OMMT/SiO2 were studied with XRD, FTIR, contact angle and mechanical properties. The study showed that with the addition of OMMT/SiO2, the contact angle of glass fiber and resin became smaller,the infiltration was increased. Physical tests showed that when OMMT/SiO2 content reached 4%, unsaturated polyester impact strength could be increased by 50%, flexural strength fell below 15%.
