Spray-Up also known as chop method of creating fiberglass objects by spraying short strands of glass out of a pneumatic gun. This method is used often when one side of the finished product is not seen, or when large quantities of a product must be made cheaply and quickly without regards to strength. Corvette fenders and boat dinghies are commonly manufactured this way.

  • Spray-Up also known as chop method of creating fiberglass objects by spraying short strands of glass out of a pneumatic gun. This method is used often when one side of the finished product is not seen, or when large quantities of a product must be made cheaply and quickly without regards to strength. Corvette fenders and boat dinghies are commonly manufactured this way. It is very different from the hand lay-up process. The difference comes from the application of the fibre and resin material to the mould. Spray-up is an open-moulding composites fabrication process where resin and reinforcements are sprayed onto a reusable mould. The resin and glass may be applied separately or simultaneously "chopped" in a combined stream from a chopper gun. Workers roll out the spray-up to compact the laminate. Wood, foam, or other core material may then be added, and a secondary spray-up layer embeds the core between the laminates. The part is then cured, cooled, and removed from the mould. (en)

  • Sproeilamineren of mechanisch vezelspuiten (Engels: spray lay-up of spray up roving) is een vormgeefproces waar in een open vorm een deel wordt gelamineerd. Het proces wordt vaak gebruikt om polyester vormdelen te vervaardigen. Bij het sproeilamineren wordt, in tegenstelling tot het handlamineerproces, met een sproeipistool (Engels: chopper/spray gun) het weefsel tezamen met de hars opgebracht. Het weefsel wordt bij het erop sproeien in stukjes van 20 tot 60 mm gehakt. (nl)
