Extracting a characteristic value concerning metal-composite-hybrids - identification of the relevant testing method
This research evaluates the bending properties of metal-composite hybrids in a three-point-testing setup and aims the identification of suitable testing method for hybrid parts. Therefore, glass fibre reinforced polypropylene is fusion bonded to steel creating one part. The particular challenge of this new material class is that there are no standardised testing methods or extracted characteristic values for comparison and designing hybrid parts. Thus, the investigated samples have both asymmetric configurations and different orientation angles. However, different lay-ups (plies with different fibre orientation angles) can be clearly distinguished within the test procedure and the different configurations could be determined as well. Moreover, the most important finding is that the sample's position - whether the composite is predominantly loaded with tension or compression - does not interfere in stiffness, but in the strength.
