Techniques commonly used to manufacture advanced composites from prepregs, which are available in unidirectional fiber or fabric form, include compression molding, vacuum-bag autoclave molding, stamp molding, thermoforming, and on-line (in situ) consolidation [3]. In compression and vacuum-bag autoclave molding techniques, the prepreg is cut to the dimensions of the structure, and the fiber directions are oriented to obtain the required... 

Soft lithography is an emerging method for micro- and nanofabrication of two- or three-dimensional structures on surfaces.73 78 This method developed by Whitesides and coworkers uses elastomeric stamps, molds, and conformable photomasks for creating patterns as small as tens of nanometers on substrates. Depending on the...

Advantages of RTM are that the molded part has two finished surfaces, and the overall process may emit a lower level of styrene vapor if the polyester resin used contains styrene. The mold, unlike a compression or TP stamping mold, is completely closed to defined stops prior to final part formation/curing. This procedure provides a more reproducible part thickness and tends to minimize trimming and deflashing of the final part. 

Stamp molding n. A compression-molding variation in which the mold is closed so suddenly that the plastic is impacted rather than pressed, as in forging. 

Molds play an important role in the fabrication of GRTPparts. Accordingly, the design and construction of molds and their components are covered Injection and stamping molds are considered... 

This technique developed by G.M. Whitesides employs elastomeric stamps, molds, and conformable photomasks to produce repetitive micro- and nanostmctures. " ...
