The present work study flexural and tensile behavior of short Kenaf fiber reinforced composites. The fibers are chemically treated in 2% NaOH solution at room temperature. Short fibers of 4mm and 8 mm are used in the present work. The composite lamina is prepared by hand molding using isopthalic polyester resin. Flexural test and tension tests are carried out as per ASTM standards. The flexural...

Replacement of dietary fat by sucrose polyester reduces fat intake. However, little is known about the effects of sucrose polyester on gastrointestinal function. To investigate the effect on gastric acid secretion and on release of cholecystokinin into plasma, we perfused eight healthy male volunteers intraduodenally with sucrose polyester, digestible fat, or saline on separate days in random o...

Fishing boats are vessels that almost 90% of the building materials made wood. The nature wood is easily weathered and attacked by destroying organisms causes fishing with to be damaged. Banana trees plants thrive in Indonesia. In addition fruit, banana tree leaves part often used for reprocessing. However, midrib cannot utilized optimally will become unused waste. Therefore, author has an inno...

In this paper, a model for the prediction of fatigue life degradation fiber-reinforced (FRP) composite materials exposed prolonged periods to real marine environments is proposed. The data collected during previous phases more comprehensive research environment-induced changes mechanical properties in FRP composites are used assess influence these on durability characteristics composites. Atten...

In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination differen...

Chemical recycling of textiles holds the potential to yield materials equal quality and value as products from virgin feedstock. Selective depolymerization textile polyester (PET) regenerated cellulose/PET blends, by means alkaline hydrolysis, renders monomers PET while cellulose remains in fiber form. Here, we present mechanism reactivity during hydrolysis. Part I this article series focuses o...

Plastics have been used by human beings in a wide variety of materials. Recently, microplastics, either primary or secondary, are encountered different part the environment on global scale. One common type microplastic is micro fiber. Microfibers known to be released from washing textile The amount fiber varies depending conditions and characterization. Microplastics can harmfull for aquatic or...

This article describes the novel possibility of the polyester (polyethylene terephthalate) surface modification by plasma treatment. Moreover, this modified polyester could be component for the composite material (with hyaluronic acid) used in the wound healing. In this study, the experimental methods: FT-IR spectroscopy, the contact angle measurement, Xray photoelectron spectroscopy and scanni...

In this research work, samples of the biocomposite were manufactured using vacuum assisted resin transfer molding (VARTM) technique, whose matrix is a polyester and reinforcement biaxial fabric (90°) made with jute fiber. Then, tensile flexural tests carried out on standardized specimens under ASTM standards, in order to mechanically characterize jute-polyester biocomposite. both destructive te...

Yarn properties can be altered through blending fibres. According to the requirement different properties can be achieved by different blending ratios. Among the different blends cotton and polyester, cotton and wool, wool and acrylic, cotton and nylon, jute and acrylic, cotton and rayon etc are common. Flax and polyester has been a popular blend now-adays and depicts excellent properties than ...
