      Waste Carbon Fibers and Easily Disposable Polyolefin Resins.

AB  - Outdated-waste-carbon-fiber-reinforced olefin composites (oCFOCs) were fabricated 
      with easily disposable polyolefin resins, polypropylene (PP), high-density 
      polyethylene (HDPE), and low-density polyethylene (LDPE), by compressive molding 
      using a hot press. The flexural and impact strengths of the oCFOCs from each 
      respective resin type and oCF content, ranging from 35 to 70 wt.%, were increased 
      by the aging treatment (120  degrees C and 95% humidity under a pressure of 0.8 MPa) 
      until an aging time of three days, due to improved resin impregnation. For the 
      oCFOC with PP, the hydrogen bond between PP and developed C-O groups due to the 
      aging treatment and the existing silane layer of oCF is considered to assist 
      cohesion between the resin and oCF. In particular, PP and 45 wt.% oCF content 
      were the most effective conditions for improving the oCFOCs' mechanical 
      properties, in addition to endowing the oCFOCs with good moldability and 
      dimensional stability. Our results demonstrate that durable recycled composites 
      can be manufactured using oCF and PP.
