Title:
ORGANIC-INORGANIC COMPOSITE CONTAINING CERAMIC PARTICLES HAVING FINE PROJECTIONS ON SURFACE THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/115916
Kind Code:
A1
Abstract:
The present invention relates to an organic-inorganic composite containing ceramic particles having fine projections on the surface thereof, in which the fine projections formed on the surface of the ceramic particles increase the coupling force with a resin and have an anchoring effect that suppresses slippage, thereby greatly strengthening the shear resistance of the interface between the ceramic particles and the resin and the shear resistance between the ceramic particles, so that the organic-inorganic composite has high mechanical strength capable of resisting various types of damage, such as a brittle fracture, a ductile fracture, and a fatigue fracture. The organic-inorganic composite comprises: a plurality of anisotropic ceramic particles having different aspect ratios; and a resin that is combined with the ceramic particles, wherein the organic-inorganic composite further comprises a plurality of projections projecting out from the surface of the ceramic particles, thereby increasing the shear resistance of the interface between the ceramic particles and the resin, and wherein at least some of the ceramic particles neighboring each other are closely arranged such that the projections partially contact each other, thereby increasing the shear resistance between the ceramic particles due to the contacting ceramic particles.
