Soft Computing in the Design and Manufacturing of Composite by Dragan Aleksendric, Pierpaolo Carlone

By Dragan Aleksendric, Pierpaolo Carlone

Due to difficulties linked to the layout and production of composite fabrics, there's a have to introduce computational and clever structures engineering method in fabrics engineering. Soft Computing within the layout and production of Composite Material offersan clever method of develop fabric engineering, and considerably improves the method of designing and production a brand new fabric. This identify contains chapters overlaying subject matters equivalent to gentle computing concepts, composite fabrics engineering, layout and production of composite fabrics, numerical modeling, prediction, and optimization of the composite fabrics functionality, improvement of the hybrid types, and regulate of the composite fabric performance.

  • Introduction of sentimental computing within the composite fabrics engineering
  • Includes actual and precise research of the present cutting-edge within the field
  • Development of the clever versions for layout and production of composite material
  • Details composite fabric functionality prediction
  • Optimization of the producing technique of composite materials

This is particularly difficult considering the complexity of the requirements generally imposed on friction materials, relating to (i) the sensitivity of the friction coefficient to changes in the brake pressure actuation, the sliding speed and/or the brake interface temperature; (ii) the wear characteristics in different regimes of operating temperature; (iii) the vehicle weight; and (iv) the characteristics of the braking system [35]. Up to now, the development of new friction materials has mostly been done empirically [36], because very little is known about the interrelated influences in the contact zone during braking.

2 Temperature and viscosity profiles for a Shell Epon 9420/9470/537 resin sensitive to thermal runaway and hot spots, owing to the heat released by the cure reaction. Furthermore, gradients in the temperature and degree of cure directly influence the transient and final stress distributions, inducing undesired residual scenarios, in particular in the case of outside– in solidification. This is generally caused by excessively fast activation of the cross-linking reaction on the workpiece surface with respect to the core, and is usually attributable to non-optimal design of the curing cycle.

This manufacturing step is commonly adopted also when high-temperature resin systems are processed. An autoclave is a pressure vessel equipped with a heating system. The term ‘autoclave’ is derived from the combination of two Greek words, auto (self) and clavis (closure), and refers to the capability of the first autoclaves to hermetically lock themselves, thanks to the inside–out (overpressure versus atmospheric) pressure. Autoclaves are usually configured as closed-end cylindrical tubes with an opening door at one end.
