The data included provides examples of what are available. As an example static properties (tensile, flexural, etc.) and dynamic properties (creep, fatigue, impact, etc.) can range from near zero too extremely high values. They can be applied in different environments from below the surface of the earth, to over the earth, and into space.

Flexibility The inherent resilience of rubber polymers often provides protection in expansion/contraction modes due to product temperature cycling and flex stress from repetitive work cycles. Plus this flexibility improves the assembly s resistance to vibration, fatigue, impact, shear, elongation, and peel forces. 

Plastics use is rather extensive in primary and secondary aeronautical structures that include aircraft, helicopters, balloons, to missiles space structures. Lightweight durable plastics and high performance RPs save on fuel while resisting all kinds of static and dynamic loads (creep, fatigue, impact, etc.) in different and extreme environments. 

For certain products long time dynamic (creep, fatigue, impact, etc.) mechanical load performances in different environments are required. Dynamic loading in the present context is taken to include deformation rates above those achieved on the standard laboratory-testing machine (commonly designated as static or quasi-static just reviewed). These slower tests may encounter minimal time-dependent effects, such as creep and stress-relaxation, and therefore are in a sense dynamic. Thus the terms static and dynamic can be overlapping. 

Unvulcanized rubber (sulphur-crosslinked) mixes are freshly coated with a 20% solution of 4,4, 4"-triphenylmethane triisocyanate (Desmodur R) or methylene chloride. After drying, the rubber is vulcanized in contact with a cleaned metal surface and a strong bond results. The reverse procedure is also satisfactory. For example, by this technique heat-, fatigue-, impact-, oil- and solvent-resistant bonds can be obtained between metals and elastomers by press or hot-air curing the green freshly milled or calendered... 

Strength is usua% the first mechanical property considered, but factors such as hardness, fatigue, impact, and stress-rupture properties are also important for many applications. 

To date, after more than 5 years in service, there have been no problems with fatigue, impact, or corrosion. 

Fatigue, impact and surface strength increased giving a tough, ductile, crack resistance structure. 

It has been found that steel fibres are particularly effective In concretes exposed to dynamic loading of any kind, such as fatigue, Impact and blast. 

Adhesively bonded structures are often subjected to time-varying loads, and it is therefore necessary to consider behaviour under creep, fatigue, impact, and so on. 

Generally speaking, when it comes to evaluating conventional materials, test samples for service life time estimation, quality, and safety analyses are collected. Data showing material characteristics are typically secured by means of optical and electron microscopes through destructive tests such as pull, compression, bending, torsion, creep, fatigue, impact, and corrosion. The same methods may be applied to a nanoscaled material.
