Adaptive mould for composite production allows for many approaches when it comes to composites both in production setups and materials. Detailed information on the different processes and materials is available here and by contacting Adapa.
A composite material is a material made from two or more constituent materials with significantly different physical properties, which when combined produce a material with characteristics different from its individual components. The individual components remain separate and distinct within the finished structure. Typical composites are done with fibers and a fluid setting component.
Composites are mostly named by their fiber constituents; fiberglass, carbon fiber, aramid fiber. Lately also naturally occurring fibers such as hemp has become mainstream, at least for some car manufacturers.
We have tested a variety of workflows and have achieved stellar results with our adaptive mould for composites.
This process is also known as chop method of creating fiberglass panels by spraying short strands of glass from a pneumatic gun.
This method is suitable for one side mold like the Adaptive Mould and can be efficient even for large quantities of composite shapes to be made cheaply and quickly without regards to strength.
The difference from spray-up 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.
Resin and Vacuum Infusion
Resin or Vacuum Infusion fits into the broad fabrication category of closed moulding processes, where composite manufacturing is conducted within an enclosed cavity.
In vacuum infusion the mould cavity pressure is lower than atmospheric pressure, i.e. resin flow is driven by vacuum. It excels in weight to strength ratio, because the amount of resin can be made to be just right.
