Abstract
In this study, the drop weight impact response of cured hybrid composite plates has been investigated. Experiments were conducted on two groups of hybrid composite plates. The first group was based on upper and lower surfaces that are made of carbon (c) with the inner plates of glass (g), while for the second group the upper and lower surfaces were examined which are made of glass (g) with the inner plates of carbon (c). The orientation angle of the plates was 0, 15, 30 and 45° and the collision energy was 12 J. Contact forces were obtained and compared for the plates with respect to the different sequence and orientation angles. Peak forces increased for all the sequences and orientation angles. However, the (g-c-c-g) stacking sequence showed a larger sensitivity to an orientation angle change. The deflections decreased for the (c-g-g-c) stacking sequence when the orientation angle increased.
Kurzfassung
In der diesem Beitrag zugrunde liegenden Studie wurde die Fallgewicht-Schlagbeanspruchung von gehärteten Hybridkompositplatten untersucht. Die Versuche wurden an zwei Gruppen von Hybridkompositplatten durchgeführt. Bei der ersten Gruppe bestanden die die oberen und unteren Oberflächen aus Carbon (c), während die inneren Platten aus Glas (g) gefertigt wurden. Die zweite Gruppe hat Glas (g) als obere und untere Oberfläche sowie innere Platten aus Carbon (c), die untersucht wurden. Der Orientierungswinkel der Platten war 0, 15, 30 bzw. 45° und die Kollisionsenergie betrug 12 J. Es wurden die Kontaktkräfte der Platten ermittelt und hinsichtlich der verschiedenen Stapelfolgen und Orientierungswinkel verglichen. Hierbei stiegen die Spitzenkräfte für alle Stapelfolgen und Orientierungswinkel an. Die (g-c-c-g)-Sequenz zeigte jedoch eine größere Anfälligkeit hinsichtlich des Orientierungswinkels. Die Verformungen nahmen für die (c-g-g-c)-Sequenz ab, aber mit ansteigendem Orientierungswinkel zu.
