Composite Properties

The biocomposites were prepared by using kenaf bast fiber mat as reinforcing materials at different percentage. The kenaf bast fiber was treated with alkaline at different sodium hydroxide (NaOH) percentage. Composites which were made from treated alkaline kenaf treated bast fiber showed better mechanical properties (tensile) than those of the unmodified. Scanning electron microscope analysis showed the evidence of the enhancement of the compatibility between kenaf bast fiber and the matrix. The percentage of kenaf fiber in composites also plays a crucial role in determining the composite properties.

Composite Properties

The biocomposites were prepared by using kenaf bast fiber mat as reinforcing materials at different percentage. The kenaf bast fiber was treated with alkaline at different sodium hydroxide (NaOH) percentage. From the results obtained, surface morphology of the treated kenaf bast fiber shows less impurity than untreated kenaf bast fiber. As for composites prepared from alkaline treated kenaf bast fiber, it showed higher mechanical properties as compared to those prepared from untreated kenaf bast fiber. The percentage of kenaf fiber in composites also plays a crucial role in determining the composite properties.

This work treats the behavior of a glass fibre/unsaturated polyester (UP) composite with structural defects subjected to the attack of two corrosive solutions: H2SO4and NaOH. The gravimetric analysis, the uptake mass of the resin, and the interfaces in the composite are established according to the proportion of the matrix/composite. The obtained results showed that, in the acidic solution, the glass fibre and the fibre/matrix interface absorption share is more significant than the alkaline solution. While the Fourier transform infrared analysis (FT-IR) of the UP resin revealed the presence of chemical degradation phenomenon (hydrolysis), the fibre corrosion was characterized by the atomic absorption analysis (AAS). The fibres/matrix interfaces degradation was confirmed by microscopic observations (SEM). The diffusion kinetics of the both acid and alkaline solutions and chemical and mechanical degradation are affected by the presence of the pores in elaborated material.

Kenaf Bast Fiber

Kenaf bast fiber reinforced unsaturated polyester composite was produced using kenaf bast fiber based on different retting process. There are two different retting method involved which are water and mechanical retting process. The composites were prepared by using hand lay-up method with different fiber loading (weight %) of 10, 15 and 20%. The mechanical test involved was tensile test and scanning electron microscope (SEM) was employed to investigate the fiber-matrix adhesion and fiber breakage. The result showed that the tensile properties of the composite increased as the fiber loading increased. Besides, the water-retted kenaf –UPE composites exhibited the highest mechanical properties as compared to mechanical-retted kenaf –UPE composites. While, the morphology analysis using SEM showed that water retted kenaf-UPE composite show better fiber distribution and better interfacial adhesion compared to mechanical retted kenaf-UPE composite.

Polyester Composite

This research has been done by reinforcing the matrix (unsaturated polyester) resin with natural material (date palm fiber (DPF)). The fibers were exposure to alkali treatment before reinforcement. The samples have been prepared by using hand lay-up technique with fiber volume fraction of (10%, 20% and 30%). After preparation of the mechanical and physical properties have been studied such as, compression, flexural, impact strength, thermal conductivity, Dielectric constant and dielectric strength. The polyester composite reinforced with date palm fiber at volume fraction (10% and 20%) has good mechanical properties rather than pure unsaturated polyester material, while the composite reinforced with 30% Vf present poor mechanical properties. Thermal conductivity results indicated insulator composite behavior. The effect of present fiber polar group induces of decreasing in dielectric strength, and increasing dielectric constant. The reinforcement composite 20% Vf showed the best results in mechanical, thermal and electrical properties.
