Carbon fiber compression molding.

These are some of the most common ways that carbon fiber is woven and seen in its final parts. According to the astm d3039 test standard 25 each tensile test sample was prepared into a. Ms 4h is an excellent low cost high performance molding compound that has been qualified to military and commercial applications. Prepreg preforms for compression molding high volume prepreg preform manufacture has begun with hexcel leading the way.

Compression molding allows for the manufacturing of intricate components with features such as holes that would otherwise have to be machined post mold. Carbon fiber gear stealth 2 0 pen with plain weave carbon fiber. Compression molding is used for high volume production is capable of detailed complex shapes and eliminates the need to use secondary parts in. Wet compression molding however does not use prefabricated sheets of resin thermoplastic polymer combined with discontinuous fibers but instead begins with dry continuous reinforcements and liquid resin.

Typical reinforcements are carbon and glass chopped fiber. Compression molding uses sheet molding compound smc bulk molding compound bmc or carbon fiber in a thermoset process to produce a greater strength to weight ratio over steel and aluminum parts.
