The polymeric reinforced composite materials (FRPs), used in various application fields, combine the high strength and stiffness of the fibers with the typical properties of polymer matrices (formability, impact resistance and chemical resistance, etc.) to give rise to a new material characterized by marked specific mechanical properties.
In the final composite, reinforcement and matrix retain their original chemical and physical identity and interacting through an area called “fiber / matrix interface.”
This work was partially financed by the Ministero dell’Istruzione, Università e Ricerca (MIUR, Rome, Italy) within the project PON01_02239 “MATRECO-Advanced materials for eco-friendly and sustainable transportation technologies” (within the frame of PON “Ricerca e Competitività 2007-2013).
The work described in this report has as its objective the development of a micromechanical tests called Single Fiber Fragmentation Test (SFFT) which allows to measure the strength of adhesion between basalt fibers and thermoplastic polymer matrices, in particular Polylactic Acid (PLA).
