I must have said the word Nomex a thousand times on this blog, but what exactly is Nomex? In short, it is a flame-resistant meta-aramid cloth material. It is an aramid material, which is the same thing as Kevlar, but it is not as strong as a bulletproof vest, but it has great thermal, as well as chemical resistance, which makes it great for racing firesuits.
The development of the Nomex firesuit has been a long road. This road has seen its share of driver deaths and injuries. Before the Coca Cola 600, I discussed the deaths of Fireball Roberts, Eddie Sachs, and Dave McDonald in fire-related crashes over the course of 6 days in 1964. What took place from there would cross the paths of racing and a young drag racer.
Bill Simpson was born in Hermosa Beach, California in 1940. He took up drag racing at a young age, and at age 18, broke both arms in a drag racing crash. As he recuperated, he thought of safety in racing for the first time. He developed the idea of an X shaped parachute, and using materials from his uncle’s army surplus shop, developed a functional drag racing parachute. Don Garlits noticed the new parachutes, and took an interest, which helped the Simpson Drag Chute company to form. As time went on, he started making other racing equipment, which caught the attention of drivers, and, oddly enough, NASA. During a project, he met Pete Conrad, who introduced the now 27 year old Simpson to Nomex in 1967.
Nomex was created in 1967, for NASA. Far from the uses it has today, its main use at the time was for the Apollo Command Module parachutes. NASA needed a material that could stand up to the heat of reentering the earth’s atmosphere, and still remain fully functional. Simpson saw what the material could do, and decided it would work well to make driver suits, and other uniform items.
Contrary to what most people think, Nomex is not fire PROOF, rather it is fire RETARDENT. It does burn, but burns at a much slower rate, and that protects the driver in the event of a fire. Bill Simpson decided to show how much better this material was by having a “burn off.” He put on one of his Simpson racing suits, doused himself in gasoline, and lit himself on fire. Though he was fully engulfed in flames, he was not hurt. Though he admits that is was a bad idea, it sold drivers on Nomex. Even today, 46 years later, Nomex is still the go-to material for driver suits.
Nomex is used for many other things. Nomex sheet is used in power cords for insulation. Fire-fighters use Nomex for protection in saving lives. Fighter pilots wear Nomex suits in case of cockpit fires. Nomex was developed for NASA and NASA still uses a lot of Nomex. It is used in what NASA refers to as the “Thermal Micrometeoroid Garment of the Extravehicular Mobility Unit”, or in regular English, the “outer layer of a spacesuit.” The spacesuits that space shuttle astronauts wore on liftoff and touchdown were primarily made of Nomex. Almost every project that NASA has done in the last 40 years involves Nomex in one form or another, so it is a very versatile material.
Interestingly, as safety concerns increased, and safety equipment changes for the better, you begin to see that Nomex is beginning to have competition in the driver suit market in terms of fire protection. While I’m typically a traditionalist when it comes to sports uniforms, for driver suits that is a great thing. Developing a new material that serves the same purpose as Nomex, but can do it better and longer is a great thing. Eventually, Nomex will go the way of typewriters, film cameras, the printing press, and the floppy disk as an invention that is obsolete but changed the world.
Paint Scheme Reviews!
Some new 2014 schemes released this week:
Danica Patrick #10 Apsen Dental Chevy SS Even though this scheme is better than the *ahem* current Aspen Dental scheme, it still does not look good. But it is still an improvement, and I’ll give it a C
Ryan Newman #31 Quicken Loans Chevy SS Great color scheme-Check, Awesome use of Northwestern stripes-Check, classic design-Check, A+ Grade, Double-Check!
Dale Earnhardt Jr. #88 National Guard Chevy SS The numbers kill what is otherwise a great scheme. I like everything else, but the color of the numbers looks really odd, and I can’t really say it adds to the car at all. Still it is a decent scheme, so I’ll give it a B
Now we move on to 2013
Denny Hamlin #11 FedEx One Rate Toyota Camry Very clean look, with a very good color scheme, can’t say anything bad about this, A+
Greg Biffle #16 Pink 3M Ford Fusion Pinkwashing is an automatic F. I hate it when companies use causes like this to move products, so I show no mercy in this sence.
Ricky Stenhouse Jr. #17 Pink 3M Ford Fusion See Above, F
Ricky Stenhouse Jr. #17 My Best Buy Ford Fusion The blue used on this scheme is a tad too light, but it is still a decent scheme, though the lighter blue takes it from the A grade Best Buy had to an A-
Joey Logano #22 Shell/Pennzoil/Hertz Ford Fusion I’ll be honest, I want to give this scheme a better grade, but the Hertz logo just looks out of place here, and it is awkward on an already iffy scheme. Best I can give it is a D-
Cole Whitt #30 Black Clover Toyota Camry Swan Racing seems to go out of its way to design bad paint schemes this year, and this scheme is no exception. It has no redeeming features at all, and earns an F-
Jeff Burton #31 Sleep Innovations Chevy SS Great color scheme, though the design on the front is a bit overdone, still a good looking scheme that earns a solid B+
Aric Almirola #41 Maurice Petty Tribute Ford Fusion Tribute schemes have worked very well across the board, and this is no exception. Simple, timeless, yet attractive, a great tribute to a great engine builder. Extra points for using Maurice’s #41 for the weekend. Interestingly, Maurice raced in a total of 26 Sprint Cup races, and had 7 top 5’s and 16 top 10’s during the 1960’s.
Travis Kvapli #93 Dr. Pepper Toyota Camry An A+ scheme all around.
