USE OF RECYCLED (CARBON) FIBERS IN WETLAID-NONWOVENS - CURRENT STATUS, POTENTIALS AND ONGOING RESEARCH EFFORTS

摘要

The wet lay process is one route of transforming recycled reinforcing fibers, mainly carbon fibers, in a processible raw material - a nonwoven. The process itself and the subsequent transformation into a composite show high potentials and severe restrictions at the same time. Economic production combined with good process ability and good surface appearance are some of the advantages. Limited fiber volume content and limited drapeability are its main drawbacks. The paper reviews these distinct features with a focus on drapeability. Ongoing research efforts are highlighted in these respects.
