Two thermocouples,
located in different points of the chamber, allow to verify the homogeneity of the temperature.
The hot air flow
enters the upper assembly and follows a path such that the whole length of the coil is invested by the
air stream.
was used as precursor fibre
The RC was
manufactured using a load of 0.5 kg, i.e. a “nominal stress” of 25 MPa, defined as the ratio of the
applied load over the cross section of the untwisted precursor fibre.
