Effect of fiber reinforcement on mixed-mode fracture of polymer mortars

摘要

The present paper is concerned with the failure analysis of cracked polymer mortar reinforced with particles from waste Tetra Pak (R) aseptic carton packages, piassava lees and glass fiber in combined mode I and II. The Brazilian disk, a classic mixed mode fracture test specimen, was adopted for the experimental characterization of the crack initiation. A slight increase in critical stress intensity factors was observed with the addition of carton particles and piassava lees. Glass fiber reinforcement promotes the highest fracture resistance to crack propagation. (C) 2016 Elsevier Ltd. All rights reserved.
