Ultra high molecular weight polyethylene fibers have been crosslinked by electron beam. The structure and mechanical properties of them have been investigated in different irradiation atmospheres. The obtained results show that the gel content and crosslinking density increase with the increase of dose,the swelling ratio and average molecular weight of crosslinked net decrease with the increase of dose,the tensile strength and failure elongation decrease with the increase of dose,the tensile modulus increases with the increase of dose. When the samples are irradiated in air,vaccum and acetylene atmospheres,the effect of irradiation in acetylene atmosphere is best.
