Abstract
A vehicle includes a vehicle body and a vehicle propulsion system. The vehicle propulsion system includes a fuel tank having a nozzle and a tank body. The tank body is made, at least in part, from carbon fiber materials. A method of producing a carbon fiber component for the vehicle is also described.
Claims18
A method of forming a carbon fiber, the method comprising the steps of:
- providing a textile acrylic fiber precursor material;
- dry-spinning the precursor material to form a plurality of filaments from the precursor material, each filament having a dog-bone shaped cross section;
- stretching each of the plurality of filaments during the step of dry spinning the precursor material;
- stabilizing each of the plurality of filaments;
- re-stretching each of the plurality of filaments after the step of spinning and before, during, or after the step of stabilizing;
- and
- carbonizing each of the plurality of filaments.

A fuel tank comprising
- a carbon fiber wrapping and
- an internal polymeric liner disposed on an inside surface of the carbon fiber wrapping and defining an internal fuel-storage space,
- wherein the carbon fiber wrapping includes a resin matrix and a plurality of carbon fibers that include dry-spun, textile acrylic filaments having a dog-bone shaped cross section.
A vehicle propulsion system comprising
- an electric motor configured to drive rotation of at least one wheel,
- a hydrogen fuel cell configured to produce electrical energy for the electric motor, and
- a hydrogen fuel tank including a tank body defining an interior fuel-storage space and a release valve coupled to the tank body and configured to release hydrogen fuel from the interior fuel-storage space to the hydrogen fuel cell during operation of the vehicle propulsion system,
- wherein the tank body includes a carbon fiber wrapping and an internal polymeric liner disposed on an inside surface of the carbon fiber wrapping and defining the internal fuel-storage space, the carbon fiber wrapping including a plurality of carbon fibers including dry-spun, textile acrylic filaments having a dog-bone shaped cross section and a resin matrix binding the plurality of dry-spun, textile acrylic filaments.
