Steels continued mechanical properties

The electrodes are manufactured from single or multistrand stainless steel wires (Fig. 4). The interconnection cables are coated with silicone. Besides a simple manufacturing technology, the electrodes demonstrate good electrical and mechanical properties [35]. In long term implantations the nerve damage due to continuous electrical stimulation was below 4.8%. Explantation of the electrodes is easy to perform [36]. 

Railway carriage interior components molded by RTM have been developed by Kobe Steel Europe with Transintech, UK, and Compin, France. A lightweight (5 kg) seat back shell with high static load and absorption capacity is molded in a modified acrylic resin (from Ashland) with a filler combination to achieve low fire, smoke and toxicity (FST) properties (which is easy to mold by RTM, with little effect on mechanical properties). A combination of glass fiber-based fabrics of 45° non-crimp (936 g/m ) with unidirectional reinforcement and continuous filament mat (450 g/m ) is used.

An further alternative approach being developed worldwide is to replace the steel completely by fibre-reinforced plastics (FRP), which consist of continuous fibres as carbon, glass or aramid, set in a suitable resin to form a composite rod or grid. These materials have high tensile strength, low density and are non-magnetic they can be used both for new structures and for repair of existing ones. The mechanical properties of FRP are determined by the amount and type of fibre, while the durability will be a function of both the resin and the fibre.
