AB  - In this study, high-density polyethylene (HDPE)/wood-flour composites with a 
      basalt fiber (BF)-reinforced shell were prepared by coextrusion. After exposing 
      these composites to ultraviolet weathering for 2000 h, their performances were 
      examined from their measurements of color, surface morphology, and chemical 
      properties. As a control, UV326 was also added to the shell formula. The 
      weathered surface was characterized by scanning electron microscopy, Fourier 
      transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy. The 
      results revealed that the shells filled with 8% and 12% BF exhibited low 
      lightness and color change in comparison to those filled with UV326 for a limited 
      duration. The composite shells with the combined BF and UV326 exhibited the least 
      discoloration and surface cracks. FTIR spectra revealed that the oxidation of the 
      composites increases with the duration of exposure to the assessment of the 
      carbonyl group concentration on the surface. The combination of BF and UV326 
      revealed a synergistic effect on the alleviation of the photooxidation of 
      wood-plastic composite shell layers, verifying the UV-shielding effect.
