AB  - The paper presents new value-added composite materials prepared by recycling tire 
      rubber, polyethene terephthalate (PET), high-density polyethene (HDPE), wood 
      sawdust, and fly ash. The composites were manufactured through the compression 
      molding technique for three temperatures (150  degrees C, 160  degrees C, and 190  degrees C) previously 
      optimized. The addition of fly ash as reinforcement in polymer blends is a viable 
      route to improve the composite" properties. The paper aims to assess the effect 
      of fly ash on the mechanical properties and water stability of the new all waste 
      composites considering their applications as outdoor products. The static tensile 
      (stress-strain behavior) and compression properties of the composites were 
      tested. The fly ash composites were characterized in terms of wetting behavior 
      and surface energies (contact angle measurements); chemical structure of the new 
      interface developed between composite" components (FTIR analysis), crystalline 
      structure (XRD analysis), surface morphology and topography (SEM, AFM). The 
      addition of fly ash promoted the development of the hybrid interfaces in the new 
      composites, as FTIR analysis has shown, which, in turn, greatly improved the 
      mechanical and water resistance. The novel all waste composites exhibited lower 
      surface energies, larger contact angles, and smoother morphologies when compared 
      to those with no fly ash. Overall, the study results have revealed that fly ash 
      has improved the mechanical strength and water stability of the composites 
      through the formation of strong hybrid interfaces. The study results show optimal 
      water stability and tensile strength for 0.5% fly ash composites cured at 190  degrees C 
      and optimal compressive strength with good water stability for 1% fly ash 
      composite cured at 150  degrees C.
