Impact Damage Behavior of Basalt Fibers Composite Laminates: Comparison Between Vinyl Ester and Nylon 6 Based Systems

PIETRO RUSSO, ILARIA PAPA, VALENTINA LOPRESTO

Abstract


Polyamide 6 (PA6) and vinyl ester (VE) basalt fabric composite laminates were prepared and analyzed in terms of flexural and low velocity impact properties in order to compare the results and evaluate the influence related to the matrix type. The BS/PA6 exhibits superior flexural performances and a higher rigidity in all tests. It is also interesting to note a particular behavior of the vinyl ester samples that can be related to the damage mechanism. After the impact tests, the specimens were non destructively investigated by a ultrasound technique to evaluate the delamination extent. These data, complemented by morphological inspections and indentation depth measurements, have provided useful information about the involved damage mechanisms.
