The resin wet lay-up forming method for composites has been in use for many years. While it is a simple process, it takes considerable experience and skill to produce results that are up to the standards people have come to expect from composites. Power and Composite Technologies has been using this method for as long as we have been in business and for many of the most demanding applications.
PCT utilizes several different manual forming methods depending on the specific demands of the particular project. Factors include cost, required strength and physical characteristics, available time-frame, and client preferences, among others. Resin wet lay-up typically refers to the impregnation of fibers in a resin bath, by hand, using special rollers and brushes, though some use it to refer to the spray lay-up process as well.
By-hand resin wet lay-up and spray lay-up are similar in that they are both done in an open mold process, and the resin cures under normal atmospheric conditions. However, the spray lay-up process requires the use of shorter fibers, which are not always desirable for every application. The hand lay-up process yields higher fiber contents, using longer fibers, and therefore can produce higher strength and stiffness characteristics.
Resin wet lay-up is not necessarily appropriate for every application, so we offer a host of other forming methods, as well. Our available processes include compression molding, filament winding and convoluted winding, long fiber thermoplastic molding, vacuum molding, laminate molding, and more. Our facilities are also equipped with the latest CNC mills, lathes, and other post-finishing equipment.
