As an example LNP Engineering Plastics, USA has been publishing results of tests that include a selection of die-cast metals compared with a 60 wt% long glass fiber reinforced nylon 6/6 compound (Verton RF700-12EM). The conclusion was that (for moisture-conditioned samples) with a density lower than metals, with the exception of certain... 

Particularly sophisticated tooling is used for major application for RTFs such as automobile air intake manifolds. These large (1.5-3 kg) moldings, in glass fiber/reinforced nylon, are IM on fusible metal cores, which are subsequently melted out, or are molded as two mirror images, which are then ultrasonically welded together.

With GFP, the notched-bar impact strength increases as the temperature rises it falls with temperature in unfilled polymers. The moisture uptake and heat expansion are lowered by glass-fiber reinforcement. The thermal-threshold tensile strength increases, for a glass-fiber-reinforced nylon 6, for example, from 75 to 245°C (at 1.85 N/mm ).

Based on the properties of glass fiber reinforced PCC, a number of products are being developed. One product is structural lumber. This lumber differs from decking because it is much stiffer and stronger. Therefore, this lumber can be used as the support structure for decks. Figure 13.3 shows the extrusion of a plastic board using glass fiber reinforced nylon 6 PCC.

Glass-fiber reinforcement of unsaturated polyester resins, of epoxies, and polystyrene had been practiced for a number of years, resulting in a considerable improvement in strength, stiffness, and dimensional stability. Later, about 1960, glass-fiber reinforced nylon 66 was also developed, by Fiberfil Inc. in the United States [47] and by ICI in England [48]. This kind of modification was subsequently applied to nylon 6, in Germany particularly by BASF and Bayer. 

Fig. 5.65 SEM of a glass fiber reinforced nylon shows excellent compatibility between the fiber surfaces and the matrix. Short, nearly lateral failure across the matrix and fiber is observed. Some glass fibers exhibit classical brittle fracture (arrow) (B). Adhesion of the matrix resin is seen (arrows) at the fiber surfaces (C).

Conditions. A product containing a test bar of Zytel 80G 33L (glass-fiber-reinforced nylon), which must elongate 4.38 percent during assembly. The bars are preconditioned to equilibrium in 50 percent relative humidity air. The strain rate used can be no faster than the 0.2 in./min. rate from available data.
