Gurit Exhibited Composite Sections of New London Double-Decker Bus at China Composites Expo 2013

  • Tuesday, 17th September 2013
  • Reading time: about 2 minutes

Gurit exhibited at China Composites Expo from 11th– 13th September.

The company’s stand at China Composites featured full-size composite components used in London buses. In addition, Gurit’s technical team presented a detailed case study, in Chinese language, as part of the Expo’s Technical Forum series.

The company says the “NBfL” initiative is an initiative to introduce a new range of double-decker buses to the capital city for the UK. The buses utilise advanced composites to achieve the necessary weight saving, whilst structurally supporting the hybrid drivetrain, meeting aggressive fuel efficiency targets and delivering iconic styling.

The manufacturer of the buses, Wrightbus, selected Gurit as its composite expert for the design and supply of the structurally loaded rear-end body panels. Gurit specified SPRINT ST70FR to meet the fire retardant requirements, and worked closely with Wrightbus to ensure the structural design; attachments and assembly methods met the performance requirements. Nine sets of prototype components, made with SPRINT ST70FR and Corecell M-Foam, were supplied to Wrightbus by Gurit during late 2011 and early 2012 to show proof of concept. The first of the new buses are now in service in London.

Gurit says its ability to supply proven fire retardant materials for the manufacture of the London buses was one of the key reasons the company was chosen for this project. Gurit has developed a range of materials to meet the most stringent Fire, Smoke & Toxicity (FST) requirements, including structural cores, phenolic and epoxy prepregs, SPRINT, laminating systems, surfacing films and adhesives. Typical applications for these products include cladding of buildings, interior and exterior train parts, buses, commercial ferries and superyachts.

Gurits presentation at the show will discuss the development of the composite solution, the driving  factors behind the structural design, the reasons behind material selection decisions, and how Gurit is successfully delivering a complete composite solution to this  project.
