  • Therefore
  • it was investigated whether a LUMiFrac centrifuge
  • which is usually used to determine the strength of adhesive bonds
  • can be utilized for testing the fatigue and tensile strength of AlSi7Mg0.6specimens
  • manufactured by laser beam melting (LBM).An adapted specimen geometry
  • considering the requirements made by the centrifuge and taking the specific characteristics of the AM process into account
  • was developed for this purpose. Testing of the specimen geometry with different surface modifications verified that it allows for testing material properties. It was shown that the centrifuge tensile testing method is suitable for determining the tensile strength of the developed specimens
  • because it delivers similar results as conventional tensile testing. Additionally
  • it has been successfully demonstrated that a specimen can be brought to failure in the centrifuge by dynamic tension-tension loading.additive manufacturing

  • Kurzfassung Kohlenstofffaserverstärkte Kunststoffe (CFK) zeichnen sich vor allem durch ihre hervor- ragenden gewichtsspezifischen mechanischen Eigenschaften aus. Bohrlöcher
  • welche z.B. für Nietverbindungen notwendig sind
  • schädigen das Material und mindern die Leichtbau- güte
  • da die lasttragenden Fasern durchtrennt werden. Eine alternative und werkstoffge- rechte Fügemethode stellt das Kleben dar. Dabei erfolgt die Kraftübertragung über die gesamte Klebefläche und somit gleichmäßiger als bei punktuellen Verbindungen. Von besonderer Bedeutung beim Kleben ist die Adhäsion
  • d.h. die Übertragung von Haftkräften an den Grenzflächen zwischen dem Klebstoff und den Fügeteilen. Um ein adhäsives Versagen
  • d.h. ein Versagen an der Grenzfläche zuverlässig ausschließen zu können
  • muss insbesondere der Einfluss der Oberflächeneigenschaften des CFK auf die Adhäsion beschrieben werden. Hierfür existieren viele verschiedene Erklärungsansätze
  • was darauf zurückzuführen ist
  • dass sich bei konventionellen Prozessen die Oberfläche- neigenschaften nur schwer getrennt voneinander betrachtet lassen. Im Rahmen dieser Arbeit wurden daher mit speziellen Prozessen gezielt Oberflächen eingestellt. Diese unterscheiden sich hinsichtlich ihrer μm-Topographie
  • ihrer sub-μm- Topographie oder ihrer Oberflächenchemie. Die Adhäsion wurde auf verschiedene Arten quantifiziert: makroskopisch
  • durch die zerstörende Prüfung geklebter Verbunde und mikroskopisch
  • durch mit Messung von Kraft-Abzugs-Kurven mittels AFM. Kopfzugproben werden mit dem LUMiFrac Adhesion Analyzer
  • zerstörende Prüfung geklebter Verbunde erfolgt entweder im Kopfzug- oder im Zugscherversuch. Reinharzproben (RTM6) werden im Kopfzug getestet
  • CFK-Proben im Kopfzug- und Zugscherversuch. Damit ist gewährleistet
  • dass sowohl Scher- als auch Zug-Kräfte auf die geklebte Struktur einwirken können.Quantifizierung der Adhäsion erfolgt mittels (geklebter) LUMiFrac-Proben. Somit lassen sich makroskopische Festigkeitswerte ermitteln.Kopfzugfestigkeiten (LUMiFrac) der strukturierten RTM6-Proben im Vergleich zu einer nicht strukturierten Oberfläche.

  • (i) carrot pectin fractions enriched in linear homogalacturonan (HG) and branched rhamnogalacturonan (RG) regions were produced
  • (ii) specific structural and physicochemical properties of the isolated pectin fractions were analyzed and (iii) stability studies of emulsions where the different isolated pectin fractions were used as the sole emulsifier were performed.
