Launweaving and realignement machine for carbon fibers

APPLICATIONS

• Innovative facility for valorization and recycling of carbon fiber composite materials.
• Production of a new semi-product : long size (50-200mm) and highly aligned carbon fibers.
• Usable in numerous industries as automotive, construction, aerospace, sport or leisure facilities.

DESCRIPTION

This machine performs the realignment of carbon fibers from carbon fibers fabrics (production off-cuts or composite materials, after solvolysis or pyrolysis). This process is in three steps:

• Unweaving of carbon fabric,
• Re-alignment of the carbon fibers.
• Calibration of tapes with a quasi-uniform surfacic mass (semi-product).

BENEFITS

This machine allows to obtain long recycled carbon fibers (50-200 mm), with more than 80% of the fibers are realigned.

Cheaper than new carbon fiber, and lighter than glass fiber or metallical alloys (such as aluminum), this semi-product in recycled carbon fiber is an environmentally friendly alternative for use on semi-structural parts.
