Webinar: Variable axial Fiber Structures The Future of an Extreme Lightweight Design?

Seminário 1 Realizado em : 16 de setembro de 2020 Horário: Das 16h às 17h30 (Horário de Brasília) Convidado: Dr. Axel Spickenheuer (IPF Dresden, Alemanha) Título: Variable-axial Fiber Structures: The Future of an Extreme Lightweight Design? Resumo: In lightweight fiber-reinforced composite structures, their intrinsic anisotropy needs to be addressed in order to fully take advantage their ability to withstand loading with lower safety factors. Stress adaptive curvilinear, also called variable-axial, fibers paths, lead to significantly increased strength- and stiffness-to-weight ratios when compared, for instance, to classical multiaxial composite laminate. For the production of composite parts based on variable-axial fiber patterns, the Tailored Fiber Placement (TFP) technology was developed at the IPF Dresden in the early 1990s. Since TFP is a technology with many degrees of freedom, generating optimized fiber layouts is particularly challenging. Within the lecture the state of the art in extreme lightweight design based on a variable-axial fiber architecture will be presented. Additionally, a short historical and technical overview of the design of variable-axial composite will be given and present state of the art modelling approached will be explained. Finally, several academic and actually industry related composite parts made by TFP will be presented.
