EVALUATION OF THE PROCESS CONDITIONS OF THE FABRICATION OF SMOOTH-SURFACED POROUS LAMINATES

Abstract

A new technique for preparing porous laminates with smooth surfaces was investigated. This method utilized a polyvinyl alcohol (PVA) sleeve for forming the smooth outer surface of the laminate. This sleeve was pulled over the laminate at the end of the precure cycle and allowed to remain until the laminate was sufficiently cured to maintain its surface contour. Additional curing, without the PVA sleeve is necessary to insure proper strength. Detailed processing conditions were determined. This new technique resulted in highly porous laminates with very similar surface appearance as nonporous laminates. (Author)
