Vacuum bag moulding for retrofitting is a semi-automatic resin infusion under flexible tooling (RIFT) technique, which allows production of quality composites. In the RIFT process, dry GF are pre-formed in a mould and are taken to the side and attached to the structure. A resin supply is then channelled to the prepreg, and both are enveloped in a vacuum bag. The flow of resin into dry GF (preform) develops the composite material and the adhesive bond between composite and structure as well. [Pg.335]

The fabrication of pol)mer composites is complex. The nature and the shape of the materials used in the fabrication are numerous and the process may differ from one application to another. In the fiber composites materials, the fibers may be discontinuous or continuous. The former may be collimated the latter may be used as preforms or prepregs with complex architectme and flow. Rheology of such materials... [Pg.719]

The mechanical properties of FRP composites are dependent upon the ratio of fibre and matrix material, the mechanical properties of the constituent materials, the fibre orientation in the matrix, and ultimately the processing and methods of fabrication, which are the subject of Part II. Chapters discuss prepreg processing, liquid composite moulding (LCM), filament winding processes and pultrusion of advanced fibre-reinforced polymer (FRP) composites. [Pg.4]
