Applications of vegetable PU resin and vegetable fibers based composites for design

The article presents an investigation into the development of composite materials using various plant fibers, mostly residual, combined with castor oil-based polyurethane resin, aiming to valorize waste as raw material, reintegrating it into the production cycle as an alternative to traditional composite materials, which have negative effects on human health and the environment. Sheets of the material were produced, subsequently subjected to subtractive manufacturing processes, in different variations targeting different applications. The results demonstrate the feasibility of creating prototypes of products using these composites, as well as highlighting potential future improvements in processes and material.
