Lapinus recently posted an extensive look at trends in the automotive braking industry. The following is a peek at the first part of the story; the entire article, including images, can be found by clicking on this sentence.
Limburg, Netherlands – The key component of any car braking system is the disc brake pad. Stopping a 1300 kg car traveling at 100 km/hour in five seconds generates more than 100 kW of heat in an area of only 50 cm2. That heat is dissipated into the brake pads. Within seconds, temperatures can reach 600°C and in extreme cases even higher.
Despite that, braking must be safe and smooth. With an increasing focus on HSE (Health, Safety, Environment) these days, disc brake pad manufacturers (compounders) are having to look for alternatives to traditional raw materials like copper and other materials, which can give rise to health and safety issues.
