The structure, material and craft of the switch valve sealing bush are studied in this paper.
Through the experiments of elastic materials, we compared kinds of elastic materials’ physical characteristics and found that the nylon composites could meet the working requirements.
With the passage of working time, water diffuses inside the nylon composites through macrocrack and micro-pore space between polymers and fiber, which causes the expansion of materials and the increase of shear force, and the service life of sealing bush reduces greatly[7].

Analysis of fragmentation of glass target with composite properties of materials under impact loading Xiaoqing Yu1, a Mao Lin2,b Na Wei3,c Li Jia4,d Jing Xiao5,e 1,2,3,4,5 Air Force logistical College XuZhou JiangSu China a,b,c,d,e 20423325@qq.com Keyword:glass;fragmentation;cone angle;crackle Abstract: Glass target belongs to brittle target.In order to make use of PVC to enhance defensible performance of glass, combining glass and PVC for a target is considered in this paper.
Introduction The brittleness broken is an important failure modes for various materials or structures.In the quasi-static loads, these broke not only with external conditions (such as mechanical loads, thermal loads, etc.), but also with the initial micro defects of material, non-uniformity, etc. related to the fine structure.Impact loads, its broken form often associated with the role of dynamic load type (such as impact velocity, inertia force effects, etc.) have a more direct relationship.In this paper, based on the shells hit experiments,PVC composite membrane solid role is used, analysis of the glass / PVC layer plywood, glass panels in the shells hit the broken pattern found broken laminated plate glass panel of two superimposed cone,and extract the failure characteristics, draw some important data, and to provide a reference for the analysis of glass breaking. 1 A bomb strike experiment Experimental specimen together by an ordinary boring flat brittle and a flexible layer of

Another feature is that the combustion materials are easy formed in the combustion process.
The combustion materials are not easy delaminated and can be ignored easily.

With continuous deformation of composite materials, debonding particles increased, thus resulting in material soften.
The results showed that the mechanical properties of materials are greatly influenced by introducing voids.
Continuous deformation of composite materials, the debonding of the particles increases, which causes softening of the material.

By adopting the asymptotic expansion method, the higher order crack tip asymptotic fields which are similar to the Williams’ solutions of plane crack problems in homogenous materials are obtained.
The boundary conditions of the crack surface are: (3) Higher Order Crack-Tip Asymptotic Field The studies of Delale[4,5] show that the crack tip stress field would be equipped with the same square root singularity as that of homogeneous materials when the material prosperities of different composite materials at the interfaces are continuous.
The effect of material nonhomogeneity appears in higher order items.
