Lamination (lay-up)

• What is lay-up lamination

  Used to make 3D products from fibre based composites e.g GRP, CFRP
• What are some examples of products made by lay-up lamination

  Boats and yachts

  Cars for theme park rides

  Props/scenery for theatre and films 
• What material are the moulds for lay-up lamination made from

  Timber

  Manu boards (plywood)

  High density modelling foam
• How is lay-up lamination carried out

  1.Mould prepped (timber, Manu boards like plywood or high density modelling foam)

  2.Mould coated with release agent

  3.Top layer of gel coat applied. Resin with pigment which may also have additives like to prevent degradation. Curing takes place

  4.Fibreglass matting laid over former. Poly resin brushed onto matting, small roller pushes out any air bubbles(stippling)

  5.  Stepc3 repeated until desired thickness is reached

  6.GRP allowed to set
