In order to reduce the appearance of aviation material mishap, it is important to predict the aviation material mishap for safety management and decision-making body.
Conclusions An aviation material mishap prediction model based on neural network and its BP algorithm is proposed.
The validation example of BP neural network on data series of flight mishap 10000-Hour-Rate shows that the built prediction model of BP neural network can has a good accuracy to aviation material mishap, and it is able to describe the development trend of aviation material safety well and truly.

The materials becoming microcapsule contain various new functions.
Today’s industry makes use of microencapsulated materials to enhance the properties of finished goods.
This property of microencapsulated phase change materials can be harnessed to increase the comfort level for users of sports equipment, military gear, bedding, clothing, building materials, and many other products.
The physic-chemical method is that the membrane and core material forming between coacervation and separation of materials.
This method is restricted to encapsulation of solid core materials, including liquids absorbed into porous solids.

A computation of the elastic properties of composite materials is another problem of the mechanics of composite materials.
The properties of materials are given in Table 3.
