Introduction Fiber-reinforced polymers (FRP) provide an increased stiffness and strength-to-weight ratio compared to those of the conventional materials, e.g. metals.
Therefore, these materials are finding more and more important for modern industry, especially in the automotive, marine and aviation industries [1].

The results showed that the composite microspheres were irregular porous materials and their average diameter was 2.18 mm.
In this paper, using quartz particles as pore-forming agent, sodium silicate as raw materials, macroporous silica microspheres with 0.1-5 mm cores were made by coprecipitation method.
TiO2 film/macroporous silica microspheres composite materials have been manufactured, which have big specific surface area and good photocatalysis properties. 2.
