The Brilliance of Bamboo

International

Ford is expanding its use of sustainable materials with one of nature’s strongest substances. 

Just in my home, I have bamboo floors, bamboo bowls and bamboo bedding. But the fast-growing perennial of the grass family may soon also be found in the garage, because Ford believes cars could be next to benefit from bamboo, which is one of the world’s strongest natural materials.

While investment in research has led to breakthroughs in new materials like super-strong carbon fiber and lightweight aluminum, nature’s wonder material may have been growing all along and as much as three feet in a day. Soon, some surfaces inside vehicles could be made from a combination of bamboo and plastic to create a super hard material.

“Bamboo is amazing,” says Janet Yin, a materials engineering supervisor at Ford’s Nanjing Research & Engineering Centre in China. “It’s strong, flexible, totally renewable, and plentiful in China and many other parts of Asia.”

The benefits of bamboo have been recognized for more than a century – Thomas Edison even experimented with it when making the first light bulb. In building, its tensile strength (or how much it can resist being pulled apart) is well known, as it can rival or even better some types of metal. And, because it grows to full maturity in just two to five years – compared to up to decades for other trees – bamboo also regenerates easily.

Over the past several years, Ford has been working with suppliers to evaluate the viability of using bamboo in vehicle interiors and to make extra-strong parts by combining it with plastic. The team has found that bamboo performs comprehensively better than other tested synthetic and natural fibers in a range of materials tests, from tensile strength tests to impact strength tests. It’s also been heated to more than 212 degrees Fahrenheit to ensure it can maintain its integrity.

The Sustainable Journey

While tests on bamboo continue, Ford is already making use of sustainable and recycled materials. Many of the sustainable materials Ford uses include: 

  • Kenaf, a tropical plant in the cotton family, is used in the door bolsters of Ford Escape;
  • REPREVE fabric, made from recycled plastic bottles, diverts more than 5 million plastic bottles from landfill annually. Ford most recently introduced REPREVE in F-150;
  • Post-consumer cotton from denim and T-shirts is used as interior padding and sound insulation in most Ford vehicles;
  • EcoLon post-consumer nylon carpeting is used as cylinder head covers in Ford Escape, Fusion, Mustang and F-150; 
  • Recycled plastic bottles are becoming floor carpeting, wheel liners and shields in several vehicles including Ford Transit and C-MAX;
  • Recycled post-consumer tires are used in seals and gaskets; 
  • Rice hulls are used to reinforce plastic in Ford F-150 electrical harness; 
  • Soy-based foams are used as seat cushions, seatbacks and head restraints in Ford’s North American vehicle lineup; and
  • Wheat straw is used in Ford Flex to reinforce storage bins. 

Ford also is working with Jose Cuervo® to explore the use of the tequila producer’s agave plant byproduct to develop more sustainable bioplastics to employ in Ford vehicles.
