Identifying the material parameters of carbon fiber reinforced plastics with strain gages, taking transverse sensitivity into account

Carbon fiber reinforced plastics (CRP) are increasingly being used for lightweight constructions, as their structure ensures good strength at low specifi c weight, reduced wall thickness and low temperature dilatation.

Carbon fiber reinforced plastics (CRP) are increasingly being used for lightweight constructions, as their structure ensures good strength at low specifi c weight, reduced wall thickness and low temperature dilatation. It is essential to know the material parameters when designing CRP components. Methods of parameter identifi cation are described many times in the references. Scharr, for determining elastic constants and Dudescu for determining thermal expansion coeffi cients, are just two examples.
