Quality Control Process of Manufactured Composite Structures

Deformation Characteristics of Composite Structures

The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...

Testing the Quality of Manufactured

We consider the problem of testing the roundness of a manufactured object using the nger probing model of Cole and Yap 2]. When the object being tested is a disk and it's center is known, we describe a procedure which uses O(n) probes and O(n) computation time. (Here n = j1=qj, where q is the quality of the object.) When the center of the object is not known, a procedure using O(n) probes and O...

Piezoelectric-based Vibration Control in Composite Structures

This paper relates to vibration control using passive electrical shunt circuits. However, the vibration shunt control efficiency relies on the optimization of the vibration energy transfer between a structure and a Lead-Zirconate-Titanate (PZT) piezoelectric ceramic material. The problem is further complicated by the material composition of the substrate or host material the PZT is coupled to. ...

Visualization Technologies in the Process of Making Composite Structures

This contribution is focussing on the application of visual elements in the process of creating composite structure with the use of technique hand lay-up Pre-preg. In this method the crucial factor is not only to specify the exact position of the applied layers but the important factor as well is the right order and orientation of individual layers which are determining the strength characteris...
