“…In these investigations Sause focused exclusively on AEsignals arising from the failure within the metallic coating. In a previous work of our group, we showed that different interface failure mechanisms of a metallised composite under peel testing could also be successfully identified by AE analysis [9].…”

“…To identify failure mechanisms in the metallised composite under mechanical loading via acoustic emission, different surface topographies are produced by varying the blasting time (2 s, 4 s and 6 s). In previous studies [9,21] the influence of the composite surface structure on the peel strength and its influence on the adhesion mechanisms under peel using acoustic emission analysis were thoroughly investigated. Furthermore it was also shown that the sandblasting process does not lead to a significant decrease of the mechanical properties of the composite plate.…”

“…In Refs. [9] and [21] a detailed study on the influence of different sandblasting parameters on the surface structure and adhesion strength using peel testing was already presented. The samples used in this investigation were taken from Ref.…”

“…A high electrical conductivity is a requirement for a successful plating process [7,8]. As consequence of a weak adhesion, the coating can detach from the FRP surface leading to a significant increase of permeability [9].…”

“…In both cases the surface is modified by pre-treatment processes, which can be generally classified as mechanical, chemical or electrical pretreatments. A detailed description of pre-treatment processes and their mechanisms and effects on their surface structures are presented elsewhere in the literature [9].…”

Effect of the dissolution time on the structure and properties of lyocell‐fabric‐based all‐cellulose composite laminates

In this study, all-cellulose composite laminates were prepared from lyocell fabric with ionic liquid (1-butyl-3-methyl imidazolium chloride), a conventional hand layup method, and compression molding. Eight layers of lyocell fabric, which were impregnated with ionic liquid, were stacked symmetrically and hot-pressed under compression molding for various times; this resulted in the partial dissolution of the surface of the lyocell fibers. The dissolved cellulose held the laminas together and resulted in a consolidated laminate. Finally, the prepared laminate was impregnated in water to remove the ionic liquid and to regenerate a matrix phase in situ; this was followed by hot-press drying. Optical microscopy and scanning electron microscopy studies were used to analyze composite structures. With increasing dissolution time, the void content in the composites decreased, and the interlaminar adhesion improved. For LC-2h and LC-3h, the highest tensile strength and modulus values obtained were 48.

Effizienter Leichtbau erfordert intelligente Werkstoffe, die vielseitige Funktionen erfüllen. Ein Lösungsansatz besteht darin, das Eigenschaftsspektrum kohlenstofffaserverstärkter Kunststoffe (CFK) durch das Metallisieren der Faserkomponente zu erweitern. Auf diesem Weg werden Funktionen, wie thermische sowie elektrische Leitfähigkeit, Kontaktierbarkeit, Fügbarkeit und Haftvermittlung im integriert. Beim Verarbeiten der metallisierten Kohlenstofffaserhalbzeuge zu kohlenstofffaserverstärkte Verbunde wird die Funktionalität vom Matrixpolymer bedeckt und ist nicht mehr zugänglich. In dieser Arbeit werden verschiedene Strategien zur Herstellung von kohlenstofffaserverstärkte Verbunde mit freiliegenden Funktionsschichten systematisch untersucht. Neben der erfolgreichen, selektiven Freilegung ist die Unversehrtheit von Fasern und Funktionsschicht sowie des Gesamtverbundes ein wichtiges Kriterium. Eine Bewertung der Prozesse erfolgt anhand mikrostruktureller Untersuchungen und anschließenden Haftzugversuchen. Anhand von elektrischen Leitfähigkeitsmessungen, Benetzungs‐ und darauf aufbauenden Fügeversuchen, können Zusammenhänge zwischen Oberflächenbearbeitung und Lötbarkeit abgeleitet werden.
