So in this article, the stability of this material was studied by aging test, methyl-violet test and gas phase chromatography test.
The results show that gas phase chromatography test is feasible for evaluating the stability of this material, but methyl-violet test is unsuitable.

However, there is lack of research on the effects of plastic materials on air flow inside the manifold.
The simulation shows that intake manifold made of plastic material have higher velocity of air flow compared to other materials.
Figure 3, 4 and 5 have shown the air velocity contour of three different base materials.
The simulation shows that intake manifold made with plastic material have higher velocity of air flow compared to other materials.

This paper presents the investigation of composite materials lamination using different materials in the structure of lamination.
An implication of the study in this research showed various behaviour of composite materials with different materials used and it showed a difference phenomenon in comparison to metalic materials.
Basically, a composite material is a combination of materials to produce another material and can be defined as a composite materials structure.

Efforts have been made to synthesize mixed-metal cathode materials such as LiNi1/3Co1/3Mn1/3O2 based materials with promising electrochemical characteristics.
This is to lower the expensive Co content and help to stabilize the materials.
The cathode materials were then fabricated for electrochemical analysis.
The materials annealed at 900 oC for 24 h show best performance over the other materials.

The disadvantage of ceramic materials is that it is heavy even though it is still currently being used.
Recycled materials have much to offer, especially those that are derived from material with the desirable properties such as titanium.
