A few comments on the study “Identification of micro‐failure processes of HDPE‐henequen
fiber composite material by using acoustic emission monitoring: Effect of fiber surface
modification,” have been argued in this research article. These comments are mostly
focused on the method exploited for fracture toughness assessment. The fracture toughness
of all compounds was utilized via essential work of fracture (EWF), but several specimens
did not consider the EWF prerequisites. These requirements are that the ligament shall be …

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 …
