The surface effect of other materials can be used to absorb much energy, so it can break the explosive conditions of the flammable media, reduce the combustion strength of the flame, protect against the explosion of the container and device, and guarantee the storage safety of the combustible, explosive and dangerous chemical materials[1-6].
In the later test, the multi-layer high-hole materials with the solid ripple can be used to further validate that the obstacle in the container can restrain the BLEVE.

Attraction forces during particle removal process [9] for (a) Large flat particle area with characteristic diameter, dflat and (b) Spherically shaped particle with characteristic diameter, dp The equation of drag force for based cleaning with different types of challenging materials [9] can be approached by the given formula as follows: FD=CDρVf22×πdp24 (1) In this way, the surface will be kept clean of particle deposits.
In specifying the design, some details must be examined, like attention on commonly used materials for camera lenses and covers can either be glass or polymer, which kinds of materials are easily exposed to dirt and other particles which cause poor visibility, etc.

Introduction As lightweight materials for fibre-reinforced composites, Non-Crimp Fabrics (NCF) are increasingly used for applications as diverse as automotive, aerospace or civil engineering.
Such gaps represent a weak point for reinforced materials due to the accumulation of resin and the fact that an accurate position of load bearing fibres is no longer assured.

Ferrocene Containing Hyperbranched Polyester: Structure and Catalytic Performance for Thermal Decomposition of Ammonium Perchlorate Fengjuan Xiao1,2, a, Yunjun Luo1, b 1 School of Material Science and Engineering, Beijing Institute of Technology, No.5 South Street, Zhongguancun, Haidian District, Beijing, China 2 School of Material Science and Engineering, Shijiazhuang Tiedao University, No.17 North 2nd-Ring East Road, Shijiazhuang, Hebei Province, China axfj66@126.com, byjluo@bit.edu.cn Keywords: Ferrocene, Hyperbranched Polyester, Catalytic Performance, Ammonium Perchlorate, Thermal Decomposition Abstract: Structures of ferrocene containing hyperbranched polyester (HBPE-Fc) was characterized by FTIR and H1 NMR.
AP is one of the most important raw materials in propellant formulations, so its contribution to the thermal decomposition of propellant is always significant and is improved by using various burn rate catalysis such as ferrocene derivatives which is important for the application of solid propellants .However, the use of ferrocene derivatives as a burn-rate catalyst brings about some setbacks, such as their migration to insulation layer during curing and storage, and their evaporation or sublimation loss during processing.
