Epoxy resins are often used as adhesives, coatings, encapsulate, casting materials, potting compounds, and binders for a large range of temperatures from -55 to 200°C.
Materials Studied adhesives are based on DGEBA and Novolac epoxy resins mixed to an amine hardener which basic molecular structures are shown on Fig. 1, 2 and 3.
The hydrothermal degradation of joints then results either from a decrease of the mechanical properties of materials (generally those of the adhesive) or from a reduction of adhesion properties, or even from both phenomena.

The electric polarity of oil flow and the insulating layer were mainly depended on the state of charged cations and anions in oil, while the surface characteristics of solid materials only played a supporting adsorption role.
The chemical compositions of solid insulating materials were cellulose and lignin.
Thus, for the same solid materials, the electric polarity of charges in oil flow differed according to the polarity of charged ions in oil.
The charged current varied with the solid materials.

This is an electro active material whose electrical resistance changes with deformation.
These properties make this material suitable to develop force or deformation sensors [15,16].
The second is to change the gripper material, e.g. use stiffer silicone rubber, but it has to be carefully performed since too stiff a material leads away from a compliant mechanism with distributed compliance.

Microstructures and Creep Behavior of As-Cast TiAl-Nb Alloy Sugui Tian 1, a, Xiaoxia Wu1, Huichen Yu2, Haofang Sun1, Zehui Jiao2 1School of Materials Science and Engineering, Shenyang University of Technology, Shenyang 110870, China 2Beijing Institute of Aeronautical Materials, Beijing 100095, China Keywords: TiAl-Nb alloy, Microstructure, Creep, deformation mechanism, Fracture mechanism.
Introduction TiAl alloys have been widely investigated due to their excellent integrated mechanical properties [1], such as excellent strength, creep resistance and oxidation resistance at high temperatures [2]. the TiAl alloys are regarded as the better high-temperature structural materials with potential applications prospect for applying in aeronautics and astronautics field, they are expected to be used for making the hot parts in aero-engines to replace the high-density metal materials [3].
Compared to the ordinary TiAl alloys, TiAl-Nb alloy has better strength at high temperature and creep resistance, therefore, the one is thought to be the excellent high-temperature structural materials with potential applications prospect [4].
The creep resistance of the metal materials is related to their microstructure and deformation mechanism which includes the dislocations slipping and twinning deformation during creep [5].
