Quality control to obtain composite laminates is frequently applied synthetic fibers/epoxy prepregs. The gel time test, resin, volatiles and fiber content, drape measurement tack tests together with water absorption capacity are methods currently employed. However, for natural fibers prepregs there a gap in the literature, which makes their application difficult. Thus this work will investigate...

The most critical failure regions are the joints between beams and columns. Under dynamic loads, bonding of rebars in concrete will be severely stressed fail. In addition to damaging column loading paths, collapse joint point may also affect structure's overall ductility capacity dissipate energy. This study examined relationship natural fiber beam-column by adding 0.5% 1.5% with an increment 0...

Abstract Fiber Reinforced Concrete FRC can be used for a variety, of applications. Fibers are utilized in concrete crack requiring reduction physical property protection, drying and improved strength toughness, increased service life decrease bleeding from water, permeability, construction value. The utilization sisal, natural fiber with mechanical efficiency, as reinforcement an exceeding matr...

Composite materials are gaining more importance in present-day engineering design and development activities because of their attractive mechanical properties [1-2] composed Fibers, Matrix Fillers. In the present research work Glass Sisal used as fibers, Epoxy resin is a matrix different volume fractions graphite filler to develop FRP composites using hand layup bag molding process study Mechan...

Three homoisoflavanones were isolated from the "piña" and leaves of Agave tequilana Weber. The compounds were identified as: 5,7-dihydroxy-3-(4-methoxybenzyl)-chroman-4-one (1), 7-hydroxy-3-(4-hydroxybenzyl)-chroman-4-one (2) and 4'-demethyl-3,9-dihydro-punctatin (3). This is the first phytochemical study carried out to Agave tequilana Weber.

In this paper we introduce the uniqueness problem of array comprehensions. An array comprehension has the uniqueness property if it de nes each array element at most once. Uniqueness is a necessary condition for the correctness of single assignment languages such as Haskell, Id, and Sisal. The uniqueness problem can be stated as a data dependence problem, which in itself can be reformulated as ...

In regression problems, making accurate predictions is often the primary goal. Also, relevance of inputs in the prediction of an output would be valuable information in many cases. A sequential input selection algorithm for Radial basis function (SISAL-RBF) networks is presented to analyze importances of the inputs. The ranking of inputs is based on values, which are evaluated from the partial ...

An increasing desire is to produce eco-friendly materials for varied engineering applications, such as natural fiber-reinforced composites (NFRCs). Although many research works on fiber polymer matrix composite exist, not much known the thermo-mechanical properties of acetic acid-treated particulate banana-sisal reinforced polyester composite. Additionally, establishing constituent with a detri...

In this present work, effects of interlamina fibre orientation on the tensile properties of composites were studied and the results were discussed. The varying types of fibre oriented composites were prepared using the compression moulding technique at a pressure of 17 MPa. The different types of oriented composites investigated were 90o/0 o /90 o, 0 o /90 o /0 o, 90 o /0 o /0 o /90 o, 0 o /45 ...
