In 1992, Ohio began using a numerical county-coding scheme to indicate the county of registration. The scheme assigns a two-digit number to each of the state's 88 counties in alphabetical order, beginning with 01 for Adams County and ending with 88 for Wyandot County. The scheme has been used on specialty plates since its introduction, and was ...
The high cost of carbon fiber is mitigated by the material's unsurpassed strength-to-weight ratio, and low weight is essential for high-performance automobile racing. Race-car manufacturers have also developed methods to give carbon fiber pieces strength in a certain direction, making it strong in a load-bearing direction, but weak in ...
The specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ...
Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. [1] Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high ...
Lightweighting. Lightweight materials such as carbon fiber are increasingly being used in cars and trucks to decrease weight while preserving strength, as shown here in this car bumper, as an example of Lightweighting. Lightweighting is a concept in the auto industry about building cars and trucks that are less heavy as a way to achieve better ...
Regulations may limit the legal working pressure to less than 40% of the rupture pressure for steel bottles (for a safety factor of 2.5) and less than 20% for fiber-wound bottles (safety factor 5). Commercial designs adopt the ISO 11439 standard. [53] High-pressure bottles are fairly strong so that they generally do not rupture in vehicle crashes.

Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
