of fiber dominated composites was not influenced by the matrix material. As long as the
fiber was not affected then the strength would remain. However this thesis will challange
that belief. The unidirectional strength in the fiber direction of fiber dominated
composites is influenced by the matrix material.
The object of this study was to examine the quasi-static tensile strength of unidirectional
polymer composites, and then use current analytic models to predict the experimental results.
The different matrix materials were polyphenylene Sulfide (PPS), vinyl ester with two
different fiber-matrix interface materials, and polyether ether ketone (PEEK).
