Elaboration and characterization of composite material based on epoxy resin and clay fillers

Abstract

The present work aims at investigating the effect of locally produced clay (Algeria), along with the effect of their size and rate on physical and mechanical properties of the composite material. This study is divided into two parts: The first one is devoted to the study of the composite material based on epoxy resin with kaolin, using different size fractions at rates ranging from 2% to 20%. The second part examines epoxy resin-based composite with calcined kaolin (metakaolin) with regard to the influence of the structure, the particle size and the charge rate on the properties of the material. It is shown that the clay fillers give the epoxy resin different properties compared to the epoxy resin alone and, additionally, reduce the cost of materials. It was also observed that the fillers enhance the mechanical properties by increasing the rigidity of the material. There is a maximum value of 2.4 GPa to 18% kaolin, or more than 325% increase in the modulus of elasticity with respect to unfilled resin for the finer particle size. It was also found that the modulus of elasticity increases with increasing the loading rate. Indeed, the rigidity increases with increasing the filler rate. Moreover, for both fillers, lower fraction yields better results. Moreover, for both types of added fillers, lower fraction yields better results.

Influence of Loading Nanoclay on Properties of the Polymer-based Composite

“…Furthermore, Fröhlich et al [9] and Donnet [23] provided information on the characterization and reinforcement loading effect on polymer-based composite, which provided an understanding of the kind of filler loaded in rubber. Nanoclay particle sizes, irrespective of chemical and morphological properties, proved to have dominated effect on polymer composite where clay is used as reinforcement [10,28,29]. Laouchedi et al [28] investigated the effect of locally produced particle sizes and loading rate on epoxy composite material's physical and mechanical properties.…”

Synergistic effect of talc/calcined kaolin binary fillers on rigid PVC: Improved properties of PVC composites

“…[7] According Liu et al, [17] treated talc significantly improves the Charpy impact strength and tensile strength of polypropylene/talc composites. Some researchers [18,19] have found that the use of calcined kaolin improves the mechanical and thermal properties of some polymers. For example, calcined kaolin-loaded epoxy resins give better results compared to kaolinloaded ones.…”

Inorganic Agents Modified Epoxy Eesin

“…Epoxy polymers give high strength, low shrinkage, good adhesion to various substrates, excellent electrical insulation, high chemical resistance, low toxicity and low cost. The three basic constituents of an epoxy system are: resin, curing agent and modifier [1][2][3][4][5][6][7][8][9][10].…”
