2. Application of centrifugation to composite materials

2.1 A reminder of the manufacture of composite materials

Readers are referred to the article Composite processing in this treatise.

• To produce a composite material, a set of reinforcements is wetted and coated with a matrix (usually a thermosetting resin) to create a continuous material. The matrix must remain liquid for the time it takes to completely invest the reinforcements.

  Pressure exerted on the composite will calibrate the thickness of the finished part, compressing the reinforcements and perhaps ejecting excess resin.

  Without this pressure, moulding is simply contact moulding. In this case, the die must solidify as quickly as possible to release the mold, in...
