AbstractThe aim of this research was to study the feasibility of using wheat straw fiber with epoxy resin for developing natural fiber-polymer composites. For this purpose, the epoxy resin was reinforced with 5, 10, 15, 20, and 25 wt.% of the wheat straw fiber with the help of the hand lay-up technique. Further, in order to improve the composite characteristic, wheat straw fibers were treated with three different concentrations of alkali (1%, 3%, and 5%). The mechanical and water absorption properties of the treated fiber composites were characterized and compared with those of untreated fiber-filled epoxy composites. It was observed that the mechanical properties and water resistance were reduced with the increase in wheat straw fiber loading from 5 to 25 wt.%. Among the three levels of alkali treatment, the composite made with 3% alkali-treated fiber exhibited superior mechanical properties than the other untreated and treated fiber composites, which pointed to an efficient fiber-matrix adhesion. The scanning electron microscope was used to observe the surface features of the wheat straw fiber.

This paper focus on Madar and Bauhinia Racemosa fibers has high potential as reinforcing agents in polymer composites. The composites plates were fabricated by hand layup method with varying the fiber weight percentage of 5%,10%,15% and 20% on mechanical and water absorption properties are analyzed. The mechanical properties of such as tensile, flexural and impact properties of madar and Bauhinia Racemosa fiber mat reinforced polyester composites were studied at first time in this work. The tensile, flexural and impact strength of Bauhinia Racemosa fiber mat reinforced polyester composites had proved higher strength performance than the madar fiber mat reinforced polyester composites.

The purpose of this study is to investigate and analyze about absorption properties of the composite laminate, microstructure hybrid sisal and banana fiber with epoxy matrix. Composite manufacturing was done by hand lay-up method with a ratio of fiber volume fraction of sisal and banana trunks 0:40, 10:30, 15:25, 20:20, 30:10, 40:0 (%) With direction of sisalana agave fiber orientation and banana fiber by fiber length according to the mold. Specimen testing was done by the water absorption test with the standard ASTM D571-8,. Test results obtained from the average water absorption properties of composites with the highest ratio of fiber volume fraction of 40%: 0% is 42.4% while the lowest average water absorption properties contained in the composite with fiber volume fraction of 0%: 40%, with percentage of 11.5%. Therefore we can conclude the increasing volume fraction of sisal fiber withidirection of  fiber orientation, the lower of water absorption properties and conversely increasing the volume of woven banana fiber orientation, the higher of water absorptionproperties.

This paper deals with the dielectric and sorption properties of some flax fiber-reinforced ethylene-propylene-diene monomer (EPDM) composites containing different fiber loadings as well as their behavior after exposure to different doses of electron beam irradiation. Three relaxation processes were evinced, a weak relaxation β at sub-Tg temperatures and two α-type relaxations above the Tg. The EPDM/flax composites exhibited higher values of dielectric constant, dielectric loss and conductivity as compared to a pristine EPDM sample. Using thermogravimetric analysis (TG) coupled with Fourier transform infrared spectroscopy (FTIR) and mass spectrometry (MS) (TG/FTIR/MS system), the degradation products can be identified. The water uptake increased as the flax fiber level increased in composites. The water uptake tests of irradiated composites showed that the highest water content was obtained for a flax fiber level of 20 phr.
