The main objective of this work is to highlight the influence of jute woven layer orientation on fracture parameters (energy release rate and stress intensity factor) of a polymer concrete laminate. The use of plant fibers, jute in this study, as reinforcements outside the polymer concrete, acquires mechanical properties, traction, and flexion, more than appreciable, however, other characteristics must be studied to ensure better integration on the market. The addition of plant fibers with different orientations is not without consequences on the mechanical behavior, in this case, on the resistance to cracking and its propagation. Fibered concretes have a very different behavior compared to non-fiber concretes, especially after the first cracking, where the fibers make their contribution by trying to stop the evolution and the propagation of micro-cracks within the matrix by making the concrete more ductile.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
