TY - GEN A1 - Rockel, Daniel T1 - Save your Skin with Skin – utiLizing leather waste fibers in flame retardant bio composites N2 - Leather is a widely used material for thousands of years and in modern days it is produced on industrial scale. This production produces high amounts of organic waste during the tannery process. These fibers can become a resource and act as a multi-functional bio-filler in flame retardant composites. This project investigates two leather fibers towards their ability to enhance the flame-retardancy in different composites. These composites use ammonium polyphosphate (APP) or aluminum trihydroxide (ATH) as flame retardants. Different silicon based synergists support polymers with ATH to reduce the load of flame retardant. The different modes of action (charring, gas phase activity, barrier effect) can be quantified of each composite. The new composites form a stable char layer resulting in an increase in residue, lower peak heat release rates (pHRR) and higher limiting oxygen index (LOI). In addition, the ratings in the UL94-classification increased up to V-0.
