Abstract
ABSTRACT The effect of surface treatments with the atmospheric pressure flame plasma (APFP) and epoxy silane (ES) is experimentally investigated to yield the best mechanical properties of silica ( ) reinforced elastomeric composites. The tensile strength of the composites is increased significantly with decrease the mean diameter. When the diameter is 2.2㎛, that of the composite is increased about 1.4 times compared to the matrix (2.52㎫). Also, the tensile strength of silica reinforced composites with APFP and ES treated is increased 8.8∼13.3%, 9.9~12.5%, respectively. When the diameter is 26.6㎛, the tensile modulus of the composite is increased about 2 times compared to the matrix (0.88㎫), and the tensile modulus of silica reinforced composites with APFP and ES treated is increased 15.6∼22.8%, 21.1~25.8%, respectively. Conventional silane coupling agent treatment have a few disadvantages because of using organic solvents. However APFP treatment is a fast, economic and eco-friendly method to improve the mechanical properties.
