Embodiment Construction

[0023] Detailed embodiments of the present invention are disclosed herein as necessary. It is to be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0024] As described in the background, the SMC process used to manufacture glass fiber reinforced parts may not be suitable for the production of carbon fiber reinforced parts. Carbon fiber bundles can cause some problems in the SMC process. For example, it may be difficult for the resin to wet (eg, fully impregnate) the carbon fibers, and the fibers may not flow well during moldin...

Abstract

The invention provides a fiber tow surface treatment system. Systems and methods for plasma treating fiber tows (e.g., carbon fiber tows) are disclosed. The system may be a fiber tow treatment system, including an air-plasma source configured to emit a plasma stream and a support surface spaced apart from the air-plasma source and configured to contact the plasma stream when emitted. First and second guides may be on opposing ends of the support surface and configured to align a moving fiber tow between the support surface and the air-plasma source. The method may include continuously transferring a fiber tow through a first guide, across a support surface, and through a second guide; and air-plasma treating the fiber tow as it crosses the support surface such that a deflection of the fiber tow from the air-plasma treatment is limited by the support surface. The disclosed systems / methods may reduce the damage to fiber tows during plasma treatment.

Description

technical field [0001] The present disclosure relates to fiber tow surface treatment systems, eg, carbon fiber tow surface treatment. Background technique [0002] Improving fuel economy is an important goal for vehicle manufacturers. The need for improved fuel economy may be driven by fuel costs, emissions standards (eg, for carbon dioxide), increased driving range, or other reasons. One way to improve fuel economy is to use lightweight materials to reduce vehicle weight. Carbon fiber is a low density material with good mechanical properties. Currently, carbon fiber is commonly used in applications such as aerospace, wind energy, sporting goods and high-end vehicles. These applications typically have lower volumes and are more expensive than high volume vehicles. In the automotive industry, applying carbon fiber to high-volume non-luxury vehicles presents several challenges. One of the challenges is to develop low-cost processing techniques for mass production. The sh...
