Development of Plastic Fracture Simulation Technology for Passenger Airbag Tear Line

Fracture and mechanical properties of an impact toughened polypropylene composite: modification for automotive dashboard-airbag application

“…Thus, POE is introduced to improve material flexibility and give better fracture resistance, especially against a heavy impact during airbag deployment. Based on the previous finding on the fracture behaviour, Sugaya et al 5 reported the development of plastic fracture technology for passenger airbag tear seams to increase the accuracy of the tear fracture process at low temperatures during airbag deployment. However, the most critical region during airbag deployment is the pre-crack areas (see Fig.…”
