Temperature and strain rate effects on PMMA under quasi-static and moderate strain rate were analyzed by Arruda [2] and material property characterization was also carried by Lee [3] under dynamic loading, they found that the increase of temperature has a drastic effect on the stress-strain behavior and thermal softening was observed for the tested materials.
It is found that temperature effect on material property is remarkable.

The materials shall be combined with a very light planking of ultrathin plastic panels as well as steel- and aluminum sheets.
The reason mainly can be seen in the different materials used.
On the other hand several manufacturing processes and varying materials are used for body components.
The project pursued a holistic approach including the entire life cycle from disassembly-friendly design of the batteries to the production of new active materials from recycled raw materials.

The resulting solid materials were washed with ultra pure water and ethanol, and freeze-dried.
The shape of the solid materials was observed using a scanning electron microscope (SEM).
The porosity of the solid materials was calculated using stereology and their density measured in a pycnometer.
Figure 2 shows SEM photographs of solid materials before and after heat treatment at 1300 °C.
Figure 3 shows SEM photographs of the heat-treated solid materials seen in Fig. 2, but sieved into a narrow size range of 25 ± 5 µm.

But these kinds of composite materials were usually prepared by powder metallurgy technology.
The coating materials were sprayed on the surface of 45 carbon steel by plasma spray equipment of DH1080.
The grooves in Fig. 7a may indicate the washing out of those materials.
