TL;DR: In this article, the authors estimate tensile and flexural strength of hybrid sisal/jute reinforced epoxy composites, which are composite samples prepared by hand layup and compression molding technique.
Abstract: In the existing scenario requisite of materials for various determinations, increase, so to organize that one's uses of biodegradables are a more electrifying area during this current period. The protagonist of composite materials contained by the sector of engineering is gradually increasing. This study objective to estimate mechanical properties like tensile and flexural strength of hybrid sisal/jute reinforced epoxy composites — the composite samples prepared by hand layup and compression molding technique. The hybrid composites of sisal/jute made-up with various weight ratios (100/0, 70/30, 50/50, 30/70 and 0/100) at 20% and 30% whole fiber fraction. The ultimate lastingness of 41.14 MPa, and 46.85 MPa have 50% jute and 50% sisal for both 20% and 30% fiber fraction respectively. So the hybrid fiber composites have properties better than non-hybrid fiber reinforced epoxy composites. KeywordsHybrid, Mechanical Properties, reinforced polymer composite and Compression Molding.

TL;DR: In this article, the effect of sisal fiber reinforcement in epoxy composites with random orientation is investigated and the results show that the fiber reinforced composites showed enhanced mechanical properties compared with plain epoxy composite.
Abstract: Due to environment and sustainability issues, this century has witnessed a global attention in green technology in the field of materials science through the development of composites. So, natural fiber reinforced composites have become important field of green composite. The main objective of this paper is to investigate the effect of sisal fiber reinforcement in epoxy composites with random orientation. Sisal fiber is abundant, low cost, degradable and good strength fiber. Sisal fiber is separated from sisal leaf using suitable techniques and those fibers surface are modified by chemical pre-treatment method (alkali treatment5%NaOH solution). Pre-treated fiber with constant length and volume is reinforced in epoxy matrix. Pure epoxy and sisal fiber reinforced epoxy composites are prepared by hand lay-up method. The prepared composites are tested as per ASTM standard. Tensile strength, compression strength and water absorption test are examined for the composite. The properties of the prepared composites are compared with pure epoxy. Experimental results show that the fiber reinforced composites showed enhanced mechanical properties compared with plain epoxy composites.

TL;DR: In this article, the use of sisal fibers, for applications in composites of polymeric matrices like phenolic resins, was discussed. And the results of impact assays had shown that the composites are more resistant than the matrix.
Abstract: There has been an increasing interest in the development of new materials that enhance the use of natural resources, in particular, renewable resources. Natural fibers as sisal belong to this category. This project aims the use of sisal fibers, for applications in composites of polymeric matrices like phenolic resins. The central objective is to produce materials more resistant than the matrix, with low density and reduction of costs in relation to the conventional materials. It was intended to promote chemical and physical modifications in the surface of sisal fibers, with the objective to improve the adhesive properties of fibers in the polymeric matrix and also to improve the mechanical properties of the composites. In order to verify the modifications reactions and the new properties acquired for fibers, they were analyzed by Scanning Electronic Microscopy (SEM), Fourier Transformed Infrared Spectroscopy (FTIR) and Thermal Analysis (TGA; DSC). Those modifications include the treatment with NaOH solution (2%) and treatments with the dianhydrides BTDA and PMDA. The new properties of the composites were analyzed by traditional mechanical assays as Charpy impact and also by water absorption assays. The fibers characterizations assays as FTIR, SEM and TGA indicated modifications in the surfaces after the treatments. The results of impact assays had shown that the composites are more resistant than the matrix. Composites with treated fibers absorbed less water than those with fibers without treatment
