This paper investigates the chemical treated fiber reinforcement effect on the chemical resistance behavior of natural fiber reinforced polyester composite. A composite material was developed with jute fiber reinforcement in the polyester matrix. Jute fiber is reinforced in three different forms namely untreated, NaOH treated and Silane treated jute fibers. The chemical resistance property of the composite was investigated as per the ASTM standard. Six different chemicals were used to investigate the chemical resistance behavior of the composite. The chemical resistance property was increased with addition of treated jute fiber. All the tested composites exhibited positive results on the chemical resistance test.

The jute polyethylene composites were developed using the hot-press technique with different fiber weight ratios. Due to the hydrophilic nature of fiber, it exhibited poor interfacial interaction to hydrophobic polymer matrix. In order to enhance the interfacial interaction between fiber and polymer, the benzene diazonium salt (BDS), propionic anhydride (PA), and 3-isocyanatopropyl triethoxysilane (silane) treated jute were used for the manufacturing of composites in this study. The chemical resistance tests of prepared composites were performed in order to probe whether these are resistant to various chemicals such as: acids, alkalis, and solvents. The effect of chemical treatments of the composites have been investigated. It was observed that the fabricated composites were resistant to all chemicals except carbon tetrachloride. The treated jute composites showed higher chemical resistance than raw jute composite and silane treated jute composite yield the highest resistance which can be suggested for making the water and chemical storage tanks.

Natural fiber-based hybrid composites with oil palm empty fruit bunches (EFB) and woven jute (Jw) fibers were prepared by hand lay-up method. Epoxy resin was used as matrix and tri-layer hybrid composites of EFB/ woven jute /EFB and woven jute /EFB/ woven jute were prepared by keeping the EFB/ woven jute fiber weight ratio constant at 4:1. The chemical resistance properties of the EFB/ woven jute/EFB and woven jute /EFB/ woven jute fiber-reinforced hybrid composites were studied by using three acids, three alkalies, and three solvents. It was found from the chemical resistance test that all the composites are resistance to various chemicals. It was observed that marked reduction in void content of composites with hybridization of oil palm EFB with woven jute fiber. Density and moisture content study demonstrated that density and moisture content property was enhanced in hybrid composites. The hybrid composites showed lower impact properties than pure EFB composite. Izod impact strength of EFB/woven jute/EFB and woven jute/EFB/woven jute hybrid was found to be 72.4 and 57.9 J/m, respectively. Impact fracture surface of the composites was studied with the help of scanning electron microscopy (SEM).

Degumming of pre-chlorite treated jute fiber was studied in this paper. The effects of sodium hydroxide concentration, treatment time, temperature, sodium silicate concentration, fiber-to-liquor ratio, penetrating agent TF-107B concentration, and degumming agent TF-125A concentration were the process conditions examined. With respect to gum decomposition, fineness and mechanical properties, sodium hydroxide concentration, sodium silicate concentration, and treatment time were found to be the most important parameters. An orthogonal L9(34) experiment designed to optimize the conditions for degumming resulted in the selection of the following procedure: sodium hydroxide of 12g/L, sodium silicate of 3g/L, TF-107B of 2g/L, TF-125A of 2g/L, treatment time of 105 min, temperature of 100°C and fiber to liquor ratio of 1:20. The effect of the above degumming process on the removal of impurities was also examined and the results showed that degumming was an effective method for removing impurities, especially hemicellulose.

Clod crushing is a principal problem with soils of high clay content. Therefore, there is a need for determining the conditions for clod breaking and clod crushing. The objective of the work was to develop a special purpose tool for single clod breaking both by rigid support of the clod and by a single clod supported by soil and to develop a machine for clod crushing. Furthermore, the purpose was to determine the relationship between the specific energy requirement for clod crushing in the function of soil plasticity and the soil moisture content by the means of the developed tool and machine. The main result of the experiments is summarized in a 3D diagram where the specific energy requirement for soil clod crushing is given in the function of the moisture content and the plasticity index for different clay soils.

ABSTRACTPoly (methylphenylphosphazene) (PMPP) is an example of a unique class of inorganic polymers with alternating – (P=N)– backbones. Chemical modification of bulk PMPP can result in changes of physical properties such as chemical resistance, onset temperature of thermal degradation, elasticity, and flexibility. Surface modification of PMPP allows tailoring of the chemical properties at the polymer interface while maintaining the integrity of the bulk polymer. In this research, PMPP thin films were treated to form carboxylate or carboxylic acid groups at the surface. Surface modification was monitored by following changes in contact angle. The hydrophobic/hydrophilic interactions of carboxylated PMPP surfaces allow for mesoscale interactions of thin polymer films.
