Improvement in surface degradation properties of polymer composites due to pre-processed nanometric alumina fillers
Parimal Maity,Subramanyam Kasisomayajula,Venkitanarayanan Parameswaran,Sumit Basu,Nandini Gupta +4 more
TL;DR: In this paper, the effect of preprocessing the alumina nanoparticles before preparation of the composite was investigated, and a direct correlation was observed between the improvement of the resistance of a composite to surface degradation and the ability of the pre-processed nanoparticles to form strong bonds with the neighboring epoxy.
Journal ArticleDOI
Processing and characterization of a model functionally gradient material
TL;DR: In this paper, a technique for preparing model Functionally Gradient Materials (FGM) using polyester resin and cenospheres is developed, where the cenosphere volume fraction in the polyester matrix is continuously varied through a buoyancy assisted casting process.
Journal ArticleDOI
Crack-tip stress fields for dynamic fracture in functionally gradient materials
TL;DR: In this article, an asymptotic expansion of the stress field around a crack propagating at constant velocity in a Functionally Gradient Material (FGM) is developed, and the analysis reveals that the crack-tip stress fields retain the inverse square root singularity and only the higher order terms in the expansion are influenced by the material nonhomogeneity.
Journal ArticleDOI
Dynamic fracture of a functionally gradient material having discrete property variation
TL;DR: In this paper, a functionally gradient material (FGM) with discrete property variation is prepared, and the dynamic fracture in this material is studied using the technique of photoelasticity combined with high-speed photography Transparent sheets required for the study are made by casting a polyester resin mixed with varying amounts of plasticizer.
Journal ArticleDOI
Epoxy composites using functionalized alumina platelets as reinforcements
TL;DR: In this article, the effect of platelet volume fraction and functionalization of the platelets on the mechanical and fracture properties of the composites was investigated and it was observed that GPS coating of platelets improved the tensile strength of epoxy while retaining the improvements in elastic modulus and fracture toughness.
