The influence of fibre diameter on the tensile strength of solution-spun, ultra-drawn, ultra-high molecular weight polyethylene (UHMW-PE, Mw > 103 kg mo1-1 ) fibres was investigated. Fibres with a wide range of diameters were produced by varying the polymer concentration in solution and by applying a drawdown to the fibres. The tensile strength of drawn fibres is compared at a constant Young's modulus in order to eliminate the influence of morphological parameters, such as degree of chain orientation and extension, on the fracture behaviour. It is shown that the tensile strength of UHMW-PE fibres is independent of the fibre diameter. In accordance with previous studies, it is found that fibre fracture is initiated by molecular events, such as chain scission.
