of air or fluid which when actuated forces the flexible wall towards the reference surface as is shown in fig9 while the composite article 68 which now includes the resin is curing the flexible male mold plays another important role as the article 68 cures it shrinks it shrinks onto the flexible male mold and away from the rigid female mold this creates a space between the article 68 and the female mold at the appropriate time the internal fluid pressure may be removed from the mold chamber 28 the vacuum may be removed and thereafter a thermoset coating may be injected under low pressure to fill the space created by the shrinking of the resin as before this coating would puddle in the bottom of the female mold until vacuum is again applied at this point external air pressure would probably be applied in the mold chamber depending on the desired thickness and quality of surface finish expected of the surface coating application of this surface coating or 34 gel coating 34 system at this point in the rfms process provides two important cost saving advantages first since the coating is applied in the mold after the article has been dimensionally stabilized the requirement for an expensive high performance low profile resin system is diminished in fact some fiber print and porosity in the resin 48 would give the advantage of added surface area to which the surface coating could bond the.
