The Challenge of Crashworthiness for Composite CarsTony Norton, Vice President, Marketing at solidThinking
This post was taken from Altair Enlighten and contributed by my colleague, Giuseppe Resta, Manager, Global Automotive at Altair Engineering.
It doesn’t seem so long ago that passenger safety and vehicle crashworthiness were the battleground where automakers differentiated their products. Now, as many OEMs have created product development systems that rely on a CAE-driven strategy to deliver excellent passive safety performance, it appears to have taken a backseat to miles-per-gallon. Almost every car commercial touts greater fuel efficiency and seeks to validate the manufacturer’s environmental credentials.
Both safety and gas mileage advances have been pushed by regulation and pulled by consumer demand. Now that the United States has set the 54.5 mpg Corporate Average Fuel Efficiency (CAFE) standard for 2025 and lower CO2 emissions have been mandated in Europe, we are entering a new era of increased challenge that could lead to significant change in the way cars are designed and constructed. OEMs and suppliers are reviewing every component and considering the technologies available to meet these new demanding standards, including investment in engineered plastic and carbon-fiber-reinforced plastics (CFRP) that offer high stiffness-to-weight and strength-to-weight ratios.
