3-triethoxysilylpropylamine (KH550) polymer was coated on quartz fibers by a simple dipping process without any complex chemical treatments in order to increase the bonding strength between quartz fibers and boron doped silicone resin matrix. The effect of coating on the interface of quartz fiber reinforced composites was evaluated by scanning electron microscope (SEM), FTIR, DTA-TG and flexural strength of unidirectional composites. Results indicated that the coating played an important role in improving the interfacial adhesion and thermal stability of quartz fibers composites. The FTIR result showed that Si-O-B bonds in silicone resin chain decomposed when the heat treatment temperature increased to 500. The composites with KH550 coatings exhibited better room temperature and high temperature flexural strength than those of the composites without KH550 coatings.
