Experimental Study on Impact Damage in CFRPs Taikun Wang1, a, Junmin Du2,b and Juanjuan Sun3,c 1The 713 Institute of China Shipbuilding Industry Corporation Zhengzhou 450015,Henan,China 2The 713 Institute of China Shipbuilding Industry Corporation Zhengzhou 450015,Henan,China 3School of Transportation Science and Engineering Beihang University Beijing 100191,China ataikunw@sina.com, bdujunmin713@163.com, csjuan1988@163.com Keywords: composite materials, pendulum test, impact damage, three-point bending, residual bending stiffness Abstract.
But the repeated low-energy impact, or impact fatigue, for composite materials components, have not draw attention.
The traditional assumption on perfect materials is not suitable for structures with initial defect or micro-scale cracks.

An approach to identify damages in materials particularly aerospace composites has been developed based on application of wavelet analysis on guided wave transient signals.
The imaging results displayed positive damage characterisation capabilities for implementation within the methodology of smart or intelligent materials.
To further validate the potential of the presented approach for practical application in smart materials, more accurate baseline comparison would be required.

The application status of waterproof bonding material of bridge deck pavement According to the survey of waterproof bonding material types which have been used on expressway in recent years, the most common materials are modified emulsified asphalt, hot modified asphalt and APP coils.
Study on the performance of synchronization gravel waterproof bond layer Synchronization gravel technology means adopt synchronous macadam car spray the macadam and bonding materials on the pavement simultaneously, then use wheel roller roll to form the synchronization asphalt gravel seal coat.
Fig.3 The shear and tensile strengths of different asphalt materials The figure 3 shows that the material types have a great impact to bond performance of waterproof bond layer, the optimal material is SBS modified asphalt, it is more suitable for waterproof bond layer of bridge deck pavement.

Influence Of Biopolymer Doped With Eco-Fillers As Sound Absorption Materials.

The global maximum value of objective function is obtained by the MATLAB program and so to determine the materials, thickness and construction details which reach to the sound insulation.
This article take the above three parameters as bounded variable, with the given expected sound insulation, predicts inverse about the parameters like the areal density, thickness, and Young modulus (or the sound wave longitude wave velocity), etc, so to determine the construction parameters as the wall materials, and thickness, etc.

The achieved materials were characterized using SEM-EDX, XRD, FTIR, and BET analysis and then applied in cationic dye adsorption.
Nowadays, eco-friendly materials produced by household waste, agricultural products, marine products waste, and soil components have been widely improved as valuable adsorbents [10].
