Abstract
Biodegradability of coir fibre reinforced epoxy composites under the effect of cow dung has been evaluated by soil burial test. Weight loss and decrease of mechanical properties with time has been observed. Biodegradation of the composites has been established by carbon dioxide evolution and by analysis of the morphology and the chemical structure of the degraded composite by scanning electron microscope and by Fourier transform infrared spectroscopy respectively. 10 Refs.

Abstract
Blast furnace slag particles (BFSP), generated in large quantities during steel manufacture consist of SiO2 and Al2O3. This study indicates that glass fibre (GF) and blast furnace slag particles (BFSP) reinforced epoxy based hybrid composites processed by hand lay-up technique exhibit improved hardness, acceptable density and well dispersed reinforcer morphology. This work highlights preparation of value added polymeric composites for tribological applications by utilizing steel plant waste. 7 Refs.

Abstract
This study describes processing and properties of nanocomposites of epoxy/ PVC with varying amounts of organo-modified clay. Organo-modified clay changes from hydrophilic to organophillic after reacting with organic-cationic surfactant. Small amounts of organoclay, added to polymer, impart many rheological characteristics and enhance physico-mechanical properties. Varying amounts of PVC added to epoxy indicated 5 phr PVC imparts best properties to epoxy. Various amounts of organo-modified clay, with loading varying from 1 to 9 phr, added to epoxy/PVC mixture, demonstrated that optimum to best mechanical properties are achieved with Epoxy/5 phr PVC/5 phr organomodified montmorillonite clay composites. 17 Refs.

Abstract
Banana fibre (BF) reinforced chemically functionalised high density polypropylene (CFPP) composites (BF/CFPP) developed by Palsule process of using modified matrix, immersed in distilled water at room temperature for long duration, showed water absorption higher than that of the CFPP that increased with increasing fibre content in the composite compositions. Tensile modulus and tensile strength of the wet composite compositions was lower than that of the dry BF/CFPP composite compositions. Voids, capillary water transport and hydrogen bonds promote water absorption in BF/CFPP composites. 19 Refs.

Abstract
Jute fibre (JF) reinforced chemically functionalised high density polyethylene (CFHDPE) composites (JF/CF-HDPE) of various compositions (10%, 20% and 30% JF) developed by Palsule process of using modified matrix were immersed in distilled water at room temperature for 6600 hours to study the effect of long term water absorption. Water absorption, thickness swelling, of the composite compositions was higher than that of the CF-HDPE and increased with increasing fibre content in composite compositions. Tensile modulus and tensile strength of the wet composite compositions was lower than that of the dry JF/CF-HDPE composite compositions. Voids, capillary water transport and hydrogen bonds promote water absorption in JF/CF-HDPE composites. 15 Refs.
