The University of Hertfordshire (UH Racing), a seasoned campaigner at the annual Formula Student educational motorsport competition, says it is using LOCTITE® products from primary sponsor Henkel “more than ever” in its 2017 car, largely due to an increase in the number of carbon fibre components. Whisper it quietly, but due to some exciting advances in the car’s development, the UH Racing team is harbouring hope that this year’s entry could provide the best-ever performance.
“We made a list of all the positives and negatives from last year’s Formula Student competition in order to identify priority areas for improvement,” explains Tristan Tissiman, Team Leader at UH Racing. “For instance, although we were a little disappointed with the power of last year’s Honda CBR500 engine, we wanted to keep it due to its high reliability. As a result, for the first time we’ve introduced a turbocharger, which has almost doubled our power output.”
A further difference relates to aerodynamics, in particular the method of manufacturing the many different carbon fibre composite components, where prepreg is now preferred to wet lay-up on the bodywork and wings (front, rear and side). The 2017 car also includes twin side pods on the wings.
“The wings are all bonded in – and together – using LOCTITE®, as are the wing mounts and close-out panels,” says Mr Tissiman. “We have a lot more bonded applications this year and we’re enjoying the benefits of using products such as LOCTITE® 9466 for our carbon fibre requirements, as well as LOCTITE® H3101 methacrylate adhesive system for the close-out panels.”
Additional car enhancements have seen the team switch from 10” aluminium to 13” magnesium wheel rims, while C17 Continental tyres have also been introduced. Other new features include the adoption of a solid axle spool in place of a differential, representing a significant weight saving, and the use of bigger disk brakes that are now CNC machined in-house to save cost. To be successful at Formula Student competitions, the teams have to prosper in a number of different disciplines. Alongside dynamic events such as sprint testing, acceleration testing, skid pan testing and endurance/efficiency testing, the teams are also judged on factors that include design, cost, manufacturing and sustainability.
“It’s amazing how many applications we have for LOCTITE® products this year,” states Mr Tissiman. “For example, we use LOCTITE® SI 5990 gasket sealant on the engine casing and sump. We’ve also used extensive amounts of LOCTITE® threadlocking adhesive and retaining compound, as well as lots of LOCTITE® cleaning products. LOCTITE® 3090 cyanoacrylate instant adhesive is another popular product around the workshop – it sticks anything and everything.”
UH Racing will be competing in three Formula Student competitions this year: UK, Silverstone, July 20-23; Czech Republic, Autodrom Most, August 2-5; and Germany, Hockenhein, August 8-13.
Although UH Racing retains Henkel’s principal support, LOCTITE® products are also being used by a number of additional universities competing at Formula Student 2017, including the University of Bath, Oxford Brookes University, UCLAN University of Central Lancashire, University of Sheffield, University of Strathclyde and University of Sunderland. In all cases, technical guidance from Henkel UK is offered.
