Potential of CFRP Used for Light Weight Structures: Some Experimental Results
This paper focuses on mechanical tests of materials and structures. Those tests are essential to assess structural integrity of aircrafts.
Material tests are performed in order to obtain material properties used for evaluation of structural integrity. That means, it is essential to obtain correct results in order to minimize uncertainties during the design process of aircraft structures. This paper shows IMA Dresdens approaches to obtain several properties for fibre reinforced materials. Testing methods to determine fatigue strength, especially for unidirectional laminates, in-plane shear modulus, compressive strength and inter-fibre failure for tension are presented.
The second topic is structural testing related to curved fuselage panel testing. A new approach to increase capabilities of that technology is presented.
