AB  - Ultra-high molecular weight polyethylene (UHMWPE) and high-density polyethylene 
      (HDPE) blend fibers with the highest tensile strength of 1.13 GPa were prepared 
      by a melt spinning process. The mechanical behavior and crystal structure of the 
      as-spun filaments and fibers were studied by differential scanning calorimetry 
      (DSC), scanning electron microscopy (SEM), X-ray diffraction (XRD), sound 
      velocity orientation testing, and tensile testing. The orientation degree, 
      crystallinity, tensile strength, and initial modulus of the fibers increased with 
      the increasing of the draw ratios. The grain size was shortened in the radial 
      direction and elongated in the axial direction. The results suggested that the 
      improvement of the tensile strength and initial modulus was a result of the 
      compact crystal structure formed by slender grains composed of highly oriented 
      molecular chains. Blending with HDPE could improve the formation of a slender and 
      compact crystal structure, and the tensile strength and initial modulus of the 
      blend fibers were higher.
