Maximum strength and performance characteristics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content.
Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same.Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
