Abstract

An effective joining between polypropylene (PP) and polybutylene terephthalate (PBT) is closely related to bonding between PP and PBT. The objective of this study is to improve the bonding between PBT and PP with a compatibilizer application between joints as tie-layer at various concentrations. Flexural strength, lap-shear strength and interlaminar shear strength of joined parts were determined to determine the adhesive bonding performance. The fracture behavior of the bonds was also investigated. It was found that using compatibilizers in a PP/PBT joining system improved the mechanical characteristics. Improved results were obtained with increasing ratios of compatibilizers in tie-layer and maximum mechanical results were achieved for 100 % compatibilizer usage in PP-PBT system.

Kurzfassung

Eine effektive Verbindung zwischen Polypropylen (PP) und Polybutylen-terephthalat (PBT) hängt sehr eng mit der Bindung zwischen PP und PBT zusammen. Das Ziel der diesem Beitrag zugrunde liegenden Studie besteht darin, die Klebverbindung zwischen PBT und PP durch Anwendung von Vermittlern als Zwischenverbindungsschicht in verschiedenen Konzentrationen zu verbessern. Die Biegefestigkeit und die Überlapp-Scherfestigkeit der verbundenen Teile wurden ermittelt, um die Adhäsionsverbindungsperformanz zu bestimmen. Das Bruchverhalten der Klebverbindungen wurde ebenfalls untersucht. Es stellte sich heraus, dass die Verwendung eines Kompatibilisators bei einem PP/PBT-Verbindungssystem die mechanischen Eigenschaften verbessert. Verbesserte Festigkeitswerte zeigten sich mit zunehmenden Vermittleranteilen in der Verbindungsschicht und die maximalen mechanischen Werte ergaben sich unter Verwendung von 100 % Kompatibilisator im PP-PBT System.
