When TiO2 is illuminated, the water on the surface can be decomposed into superoxidant ·OH radical, which can be used to oxidize the poison inorganic and organic materials.
Heteropoly acid loaded catalysts not only can play a synergistic effect with TiO2, but also can play the role of the doped polyaniline serve to enhance the photocatalytic activity of composite materials [6].
At the same time, their activities were compared with those of the related materials such as TiO2 or PANI/TiO2, and α-SiW11Ti/PANI/TiO2, the results were given in figure 5.

These will help to process designing of unsaturated
polyester resin used in advanced composite materials.
Since the mechanical properties of resin matrix composite materials are dependent on resin cure properties and cure history, the cure kinetics behavior are important for the quality control of thermosetting resin matrix composite materials.
Unsaturated polyester resin is the most extensively used in advanced composite materials.

Introduction
With the rapidly increasing use of composite materials and adhesive, much attention has been paid
to the interfacial crack by researchers.
The fracture of composites and bonded dissimilar materials is induced mainly form the interfacial region.
It is useful to design and manufacture composite materials for which we know the fracture behavior of their interface.
Hence, problem of interface crack in dissimilar materials is very important.
The numerical solutions are discussed in the analysis of a penny-shaped crack between two dissimilar materials [1-5].
