Nonwoven fibre-reinforced thermoplastics (nw-FRTP) are traditionally thermoformed in processes requiring
costly moulds. A more fexible approach suitable for prototype and small-batch production could be
incremental sheet forming (ISF). While ISF of metal sheets has long been a subject of research, nonwoven
reinforced organo sheets have not been investigated yet. Therefore, this study uses an incremental punch
test to examine the fundamental characteristics of nw-FRTP in incremental forming. A robot-guided tool
with a hemispherical tip and localisable heating are employed to deform a nonwoven recycled carbon bre
(nw-rCF) reinforced organo sheet. Supplementary material investigations are carried out to understand the
observed effects. Results indicate successful localization of heating and deformation. Despite challenges
such as temperature gradients and material deconsolidation, the experiments demonstrate promising potential
for the incremental forming of nonwoven organo sheets.
