Impregnation studies and mechanical characterization of cellular, natural, fiber-reinforced, composite structures

With the use of natural fibers as a substitute for synthetic reinforcements, a significant contribution towards advanced ecological and efficient lightweight structures can be made.Within this article, the polyurethane (PUR) spray coat method is used for the manufacture of natural fiber-reinforced composites based on the fiber materials linen and hemp. Both the investigation of the mechanical properties and the yarn impregnation, as a reference for the composite quality, are of major interest and help to evaluate the potential of these bio-based materials as a contribution towards advanced lightweight components.

Kompozyty wzmocnione włóknami naturalnymi na bazie lnu i konopi wytwarzano metodą warstwowego natrysku poliuretanu (PUR). Zbadano proces impregnacji przędzy i właściwości mechaniczne otrzymanych kompozytów oraz oceniono możliwości zastosowania takich materiałów pochodzenia naturalnego w zaawansowanych lekkich elementach konstrukcyjnych.
