Ticona and Rinspeed Introduce BamBoo Concept Car

20 September 2011

Ticona and Rinspeed have introduced the Bamboo concept car at the Motor Press Club (MPC).

Ticona explain that this is the second time they have worked with Rinspeed and they supply them with design elements as well as composite structural components.
Rinspeed describe the BamBoo as a lifestyle vehicle and say it has environmentally-friendly electric propulsion and is setting new standards in car design, fun and weight. They say they have been creating concepts and building concept cars for over 30 years. Ticona were keen to support the construction of the current concept car by supplying its materials which guarantee the reduced weight.

Ticona say that their materials have offered the greatest possible individualisation thanks to a freedom in design and production benefits, and greater reach thanks to lower weight. In the ‘BamBoo’, unidirectional tapes made of Celstran CFR-TP PP GF70 were used in the under body and wheel arches and they explain that when manufacturing the 20-mm-wide tapes they worked with Oxeon. For the under body, two layers of the fabric were pressed to create a 1-mm wall thickness while three layers are used in the wheel arches to achieve greater stiffness. Kringlan Composites manufactured the components. The instrument panel cover made of Celstran GFR-TP POM GF60 also consists of tapes produced by Oxeon and thanks to their homogeneous, smooth surface are also applicable in the interior.

Ticona also supplied Celstran tapes of the types CFR-TP PPS CF60 for the tailgate and roll bar. These were wound by AFPT without an inner core whereby the cross-winding ensures particularly high stiffness. For the roll bar, the winding process made it possible to construct a structural component: the carbon fibre semi-finished product was integrated directly in the vehicle structure to connect the cockpit with the vehicle substructure. They say the stability achieved would only have been possible otherwise with a significantly heavier metal component and would have led to 20 or 50 percent additional weight with the use of aluminium or steel respectively.

Various parts of the concept car, including the interior blinds made from Hostaform POM were painted by well-known New York artist James Rizzi. The ‘Bamboo’s’ roof pole includes Ticona’s new product novelty Hostaform MetaLX (XT). Ticona explain that, compared to other impact-strength modified POM materials, this material sets new standards in matters such as impact strength and joint line integrity. They say this innovative material is becoming increasingly important in car manufacturing as a metal substitute since it weighs less and is easy to process yet has the look of a metal. The material is cost-efficient as it eliminates the need for post hoc metal painting of the parts.
