Comments on “Identification of micro‐failure processes of HDPE‐henequen fiber composite material by using acoustic emission monitoring: Effect of fiber surface modification”

Abstract In this article authors emphasize, with solid scientific foundations, the relevance of essential work of fracture (EWF) to obtain fracture toughness in natural fiber reinforced composites presented on paper “Identification of micro‐failure processes of HDPE‐henequen fiber composite material by using acoustic emission monitoring: Effect of fiber surface modification” [Polymer Composites (2023)]. The significance of fiber/matrix interface adhesion relies strongly on chemical interactions, which is of great importance for composite's potential applications. Therefore, fiber surface modification implies a profound study where mechanical behavior must be characterized. Further vital information has been considered in this article to support the results on such studies.
