Cannon Tri-laminates Ltd have developed and patented a unique and innovative soft top convertible car hood material. It increases fuel efficiency in convertible cars by trapping heat through the inventive addition of titanium dioxide to the polychloroprene (neoprene, CR) compound. This assists in reflecting radiant thermal energy, either hot or cold, back into the car.
However, the most significant part of the automotive materials invention is the single deposited layer of 98% pure aluminium on the inner polyester dobby fabric surface. The aluminium is there to reduce the amount of work required by the car’s heating / air conditioning system, which in turn lessens the cars’ fuel consumption thus improving both the cars’ carbon footprint and running costs.
In addition to the above, the patent outlines and protects a full range of metallized butyl rubber coated tri-laminate divers’ dry suit materials.
International Patent Application No.PCT/GB2009/002298, dated 29th September 2009 and has been accorded publication No.WO2010/038007, published 8th April 2010.
Cannon Tri-laminates Ltd has protected its patent rights by the filing of the National phase application in Europe and the USA on the 2nd April 2011.
The separate attachment (named Lab report 1) compares Cannon Tri-laminates Ltd’s new metallized soft top convertible car hood tri-laminate material, yielding 38% NIR reflectance, compared to the standard (black) car hood tri-laminate material, which only yield 2% NIR reflectance.
