... to insufficient diffusion time. If a well-impregnated prepreg is used, then only the ply interfaces need be consolidated. However, if there are intraply voids, then the process time is so short as to be insufficient to heal and consolidate these voids, and a post-consolidation cycle will be required to achieve...

... impregnation of thermoplastics, a requirement for the semicrystalline materials that will not dissolve in solvents, is much more difficult than the equivalent process for thermosets. Much higher temperatures are required to melt the high molecular weight resins, and even at their melt temperature...

... is limited, it is evident that impact-damaged thermoplastic laminates are insensitive to fatigue loading. Post-impact compression strength and compression fatigue data for both the thermoplastic and the thermoset laminates are plotted in Fig. 8.35 and 8.36 , respectively. Again, the 10/80/10 layup...

For the liquid-containing binders, the product is weak and requires considerable care. The binder is removed as part of the sintering cycle. The product shape depends on the extrusion die...
