Performance of wood-ceramic composites impregnated with methyl triethoxy silane modified sol

Wood-ceramic composites which demonst rate some unique characteristics have at tracted scientists’ research at tention lately. A modified sol prepared through the methyl triethoxy silane (MTES) hydrolysis process was impregnated into the wood cells with vacuum-pressure cycles. The alternate pressure cycles overcame some barriers of slow and incomplete impregnation that the previous processing method presented. The results indicate that wood-ceramic composites made with the METS modified sol through the alternate pressure cycles exhibit improved water-repellency and plasticity，and the mechanical property is also enhanced.
