Production Processes
vacuum bagging wet lay up
Manual impregnation and lay-up of fibers. Peel ply and bleeder to be put in place. Build-up of vacuum bag. The vacuum bag film enables the build-up of vacuum pressure, to remove excess thermosetting resin during the liquid stage. Afterwards cure of wet laminate under vacuum.
Resin Infusion
Lay-up of dry fibers/fiber package. Peel ply, flow mesh, resin flow and vacuum channels to be put in place. Build-up of vacuum bag. Impregnation of composite package through injection of thermosetting resin via drop of pressure generated through vacuum.
Autoclave process
Prepregs to be put into the mold. Peel ply / release film (perforated) and bleeder to be put in place. Build-up of vacuum bag. Prepregs are cured under pressure and vacuum in the autoclave in connection with temperature.
wet compression molding - processing
Fibers/Fiber package wet / prepreg to be put into multipart mold. Close mold.
Processing / Advantages-Disadvantages
resin transfer molding - processing
Dry fibers/fiber package to be put into multipart mold. Close mold. Thermosetting resin is injected via low pressure.
