Abstract

In this study, the influence of using compatibilizer as tie-layer between fiber matrix interfaces in continuous aramid fiber reinforced high density polyethylene (HDPE) composites was investigated. Maleic anhydride (MAH) grafted polyethylene and ethylene-methyl acrylate-glycidyl methacrylate (EMA-GMA) terpolymer were used as compatibilizers at varying layer numbers. Adhesion strength was determined by T-peel test, and tensile test was carried out. It was found that higher MFR (Melt Flow Rate) valued matrix and compatibilizer application increased the mechanical performance. The maximum strength values were obtained with EMA-GMA applications. In observations of peeled parts and cross-sectional slices, interface adhesion was investigated and failure patterns were determined. It was seen that the samples with compatibilizer had more wetted portions especially the EMA-GMA tie-layered ones.

Kurzfassung

In der vorliegenden Arbeit wurde der Einfluss von kompatibilitätsverbessernden Zwischenschichten zwischen Fasermatrix-Grenzflächen in Aramid-HDPE-Kompositen (High Density Polyethylen) untersucht. Es wurde hierzu ein mit Maleinsäureanhydrid (MAH) aufpolymerisiertes Polyethylen und Ethylen-methyl acrylat-glycidyl methacrylat (EMA-GMA) Terpolymer in verschiedenen Lagenanzahlen verwendet. Die Adhäsionskraft wurde mittels eines Winkelschälabzugtests untersucht, ebenso ein mechanischer Zugtest. Es konnte gezeigt werden, dass Materialien mit höherem Schmelzfluss Index (MFI) sowie der Einsatz von kompatibilitätsverbessernden Schichten mechanischen Eigenschaften verbessern. Die Maximalwerte wurden erreicht mit der Verwendung von EMA-GMA. Mit Hilfe von Untersuchung der abgeschälten Prüfkörper und Querschnittsproben wurde der Grenzflächenverbund analysiert und Schadensmuster bestimmt. Es konnte gezeigt werden, dass in Proben mit kompatibilitätsverbessernden Zusatzschichten mehr benetzte Anteile vorhanden waren, insbesondere bei den EMA-GMA-haltigen Materialien.
