Carbon fiber preforming

During the preforming process, reinforcing fiber is pulled through mechanical guides into a robotic machine that chops and sprays the fiber sections and a binder material onto a screen typically shaped like a finished part…more fiber is programmed to be allocated to areas that must withstand more stress.

Necessary rock studies of the gabbro and andesite basalt groups for the suitability as the raw material base for the production of continuous basalt fiber (CBF). A unique technique including laboratory melting and pilot-industrial melting at the high-tech equipment.

Air flow drawn through the screen holds the chopped fiber and binder in place; the traversing section then forces hot air through the preform to set the binder and preconsolidate the preform.

Next, a second robot moves the preform to the final mold inside a press where a 2-part structural reaction molding resin is injected into the preform.

The mold closes to facilitate distribution of the resin and part consolidation as the resin cures.

The final part is now ready for finishing and installation.
