Abstract

The interaction between direct fluorinated carbon fibres and various fluoropolymers (ethylene-chlorotrifluoroethylene, poly vinylidene fluoride, fluorinated ethylene propylene copolymer and tetrafluoroethylene-perfluoro alkoxy vinyl ether copolymer) was studied by means of direct wetting measurements between fibres and the polymer melts and single fibre pull-out tests. The results of both techniques allow the adhesion behaviour between the fibres and the matrices to be predicted. The results obtained show that a low degree of surface fluorination of carbon fibres leads to an improved wettability between the fibres and fluoropolymer melts and this is an indicator for an improved thermodynamic work of adhesion. The apparent interfacial shear strength as measure of practical adhesion, determined by the single fibre pull-out test, increases with increasing degree of surface fluorine content up to a maximum, which depends on the degree of fluorination of the matrix used. The improved interaction between the fibre and the matrix is due to an enhanced compatibility at the fibre/matrix interface.

Funding

Our research was made possible by the financial support of the Engineering and Physical Science Research Council (EPSRC), UK (Grant Award No: GR/S75673/01). We thank George Shia and Vladimir Arye for arranging and assisting with shipping and fluorinating the fibre samples (Lodester, Inc., Howell, NJ, USA). We really appreciate the help from Steven Lamorinière (PaCE, Imperial College London) for taking the SEM images and Mrs. Sarah Payne (Department of Chemical Engineering, Imperial College London) for her valuable comments. Also we would like to acknowledge the help and invaluable input of Dr. Graham Beamson and the support of the CCLRC (Daresbury Laboratory, Warrington, UK) for enabling the XPS characterisation of the fluorinated carbon fibres. We are grateful to Dr Eckhard Schulz and Frau Martina Bristritz (BAM – Federal Institute for Materials Research and Testing, Berlin) for their valuable comments and assistance in conducting the single fibre pull-out test.
