Dry fabrics are laid up interleaved with layers of semi-solid resin film supplied on a release paper. The lay-up is vacuum bagged to remove air through the dry fabrics, and then heated to allow the resin to first melt and flow into the air-free fabrics, and then after a certain time, to cure.
Resins: Generally epoxy only.
Cores: Most, although PVC foam needs special procedures due to the elevated temperatures involved in the process.
Aircraft radomes and submarine sonar domes.
