The usage of composite material has been increasing day by day over the years due to the excellent properties being offered by them such as lower volume-to-weight ratio, improved toughness, recyclable, environment friendly and also due to their short cycle productivity, easiness in fabrication, long lasting life span etc. This work presents study of mechanical and tribological behaviour of ABS polymer matrix filled with micron-sized inorganic and Natural / Green fillers. The main purpose behind this work is to compare the performance of composites with different class of fillers. The experimental results unveil that the composite with inorganic fillers perform better than with natural based fillers.

The piston of the internal combustion engine is one of the most complex parts among all engine components. During the operation, the pistons of IC engines are typically subjected to high loading and wearing. To withstand these, they require high mechanical properties and excellent tribological properties. This chapter aims to compare the mechanical as well as tribological properties of silica-gel-reinforced aluminium composite with aluminium alloy, which is used in manufacturing of piston of IC engine. Initially silica-gel-reinforced aluminium composite was fabricated with base material aluminium and six different percentages of silica gel reinforcement by stir casting method. After that, mechanical and tribological properties of silica-gel-reinforced aluminium composite were estimated and the tremendous mechanical and tribological properties among all percentages by different optimization techniques were found. The authors then compared the admirable properties of aluminium composite with aluminium alloy for manufacturing of piston of IC engine.

Die Verpackung von Pouchzellen besteht aus einer dünnen Aluminiumverbundfolie, die zu Halbschalen tiefgezogen wird. Um diesen Prozess beherrschen zu können, muss zunächst das Umformverhalten der Folie charakterisiert werden. In diesem Fachartikel werden daher Erichsentiefungsversuche diskutiert. Aus ihnen geht hervor, dass das Verbundmaterial isotrop ist und die Parameter Foliendicke, Matrizenradien sowie Temperatur das Umformergebnis der Folie maßgeblich beeinflussen.   The packing of pouch cells consists of a thin aluminium composite film formed into half shells by deep-drawing. In order to be able to control this process, the forming behaviour of the film must first be characterized. Therefor, this article discusses the Erichsen cupping tests. These tests show that the composite material is isotropic and the parameters such as film thickness, die radius and temperature have a significant impact on the forming result of the film.
