| Abstract: | This paper disscuses the development of carbon/epoxy stringer
preforms of a corrugated cylinder for a certain type of satellite.The change
of the property of the resin matrix during curing process is studied by
using a method called Dynamic Dielectric Analysis (DDA) to determine the
optimum technological parameters for prebleeding of the prepreg and the
precompaction of the preforms.The curing degree of the preforms is also
determined using the dielectric loss curves. The forming of the preforms are
carried out on a soft-hard sectional die and the preforms developed satisfy
the requirements of the manufacture of the carbon/epoxy corrugated cylin-
der which has passed the ground mechanical tests later. |
