Punch Powertrain Reveals New Solar Car

30/06/2017

 

With their minds fixed on the goal of winning the world championship for solar cars in 2017, the Punch Powertrain Solar Team has been working non-stop for the last 12 months to design and build a new and optimized car powered solely by the sun. On 21 June 2017, the team could finally reveal the new car to the world.

In July 2016, the Punch Powertrain Solar Team began the race against time to finish their new solar car “Punch 2”. The team is comprised by 21 students from various fields of engineering studies such as electro-mechanical, electronic and chemical. Powered by enthusiasm for engineering and the constantly developing field of renewable energy, the team has worked tirelessly to complete all design and construction in just 12 months.

To win the 2017 Bridgestone World Solar Challenge - the world championship for solar cars - the car must be as energy efficient as possible. Thus, the car must be as small and lightweight as possible, as wind resistance and weight are two of the main energy loss factors. However, the car must still be robust and able to contain all necessary components. This sums up the main challenges for all teams participating in the world championship.

ITW Engineered Polymers is proud to have been a small part of the process by supplying Plexus adhesive materials to the team. During construction, various complications required specialized adhesive products to make the construction as efficient as possible and ensure an optimized result. Production responsible, Lander Hollevoet, explained one of the issues:

- To make the structure of the car strong and stiff enough, we have to add reinforcing ribs. In the past, these ribs were laminated into the carbon structure of the car. This made applying the vacuüm extremely complex and time consuming. To make the production process simpler, we produced the ribs separately and then used Plexus adhesives to integrate the ribs inside our solar car. To glue the ribs to the structure of our car, the good gap filling of the plexus adhesives is a very useful property when compared to other adhesives. This is important as all the ribs are hand-made and it is very difficult to make the ribs fit exactly in the car.

The team now successfully presented a fully functioning and streamlined solar powered car and is ready to begin preparations for the upcoming 2017 Bridgestone World Solar Challenge. We, at ITW Engineered Polymers are always happy to hear about new and exciting projects with our materials. We wish all the best for the Punch Powertrain team at the 2017 Bridgestone World Solar Challenge.
