Non-autoclave processing of honeycomb sandwich structures: Skin through thickness air permeability during cure

Véronique Michaud

In non-autoclave processing of sandwich structures, the pressure level inside the honeycomb becomes a critical process parameter, which depends on the permeability to air of the upper skin. In this work, prepreg and adhesive permeabilities were determined ...
