Manufacturing Process for Wind Energy: Hand Lay-up, Prepreg (Pre-forming), Vacuum Infusion (Vacuum Bagging)

• Hand Lay-up

  Resin mix and fiberglass reinforcements are laid into mold layer by layer, completely impregnated with air bubble removed, laminated to designed thickness and cured.

  

• Prepreg (Pre-forming)

  An intermediate molding process where fiberglass reinforcements (roving or fabrics) and resins are impregnated evenly and partially cured as pre-formed materials, which can be directly processed tor final products without adding more resin.

• Vacuum Infusion (Vacuum Bagging)

  Air is extracted completely from inside the vacuum bag with fiberglass reinforcements, and resin is forced by pressure into the reinforcements, uniformly impregnated and cured to form the laminates after vacuum bag removal.

  

Fiberglass Products for Wind Energy

• Roving for Wind Energy

  Fiberglass roving for wind energy is compatible with EP. VE and UP resins and used to produce wind fabrics with last wet-out and high strength & modulus.

  

• Multi-axial Fabrics for Wind Energy

  【Description】

  
  

  Multi-axial fabrics are none-crimp fiberglass reinforcements made on a warp knitting loom where fiberglass weft and warp are oriented at set angles by one or multiple layers and stitched-bonded. Each multi-axial fabric can be combined with chopped fiber, veil, for enhanced performances. It is widely used in wind energy to produce moulds, wind blades and nacelle, etc.

• PP Core Mat

  【Description】

  
  

  PP Core mat is a combination of a none-woven PP (polypropylene) core, binder-free chopped fiber and warp & weft layers, stitch-bonded with polyester yarn on a warp knitting loom. It is compatible with UP & EP resins and typically used to produce nacelle for wind energy.

  

• 【Properties】

  
  

  ◎Special resin conductive layer, high resin flow and fast curing;
  ◎Optimum thickness, less reinforcement placement and higher working efficiency;
  ◎Capable for high part flexibility, multi-thickness and excellent part integrity;
  ◎Special fabric construction, higher mechanical properties for composites with reduced weight.
