The interfacial properties of the epoxy matrix and organic short fiber with enlarged ends were investigated in this report. The adhesion strength was measured by means of single fiber pull-out test and dynamic mechanical analysis (DMA). The results showed that the incorporation of the enlarged-end organic short fibers can improve the interfacial adhesion between the matrix and the fiber, and the enlarged end is helpful to transfer the interfacial shear stress.

PBO super fibre is submitted to a corona treatment, and the properties of the interphase between PBO fibres and epoxy matrix systems are optimi z ed by a surface treatment process of the fibres. The relation is studie d between this surface treatment and the resulting chemical and physical surface st ruc ture, as measured with XPS,FT-IR,SEM and surface wettability. The adhesio n strength in fibre-epoxy systems, as measured with single-fibre pull -out and short beam shear experiments, has been established and related to the macromechanical data of real composites. It is concluded that corona- treated fibres may cause 25.6 % improvement in the interfacial shear strengt h(IFSS) due to the increase of the oxygen surface content and the well we ttability to water. But the short beam shear strength values from the cor ona-treated and untreated fibres showed only small differences.
