Švec I., Hrušková M. (2015): Characteristics of wheat, barley and hemp model composites. Czech J. Food Sci., 33: 66–71. Barley is known as health-benefit raw material, mainly due to beta-glucan. To explore the nutritional benefit of barley and hemp plants, wheat-barley flour premixes were prepared (70 : 30 and 50 :0 50 w/w, respectively). Hemp flour of wholemeal and fine type was added to each ...

Structural strengthening is needed in buildings that experience a decrease serviceability, inappropriate quality of existing concrete, and unexpected natural events such as earthquakes. One method has been widely used for structural external restraint using synthetic Fiber Reinforced Polymer (FRP). External restraints on concrete can significantly increase the strength ductility concrete. The u...

There are many types of natural fiber including hemp, flax, jute, wood fiber, rice husks, straw wheat, oats, bagasse, barley, grass reeds, banana oil palm empty fruit bunch, coir, sisal, cotton, kenaf, ramie, water pennywort, paper-mulberry, kapok, abaca, pineapple leaf fiber. The production in India is 13.5 million tons per annual. Banana forming generates more quantity biomass which goes as w...

The following review of literature regarding the pharmacology of marijuana is intended to demonstrate its mental and physical pharmacological effects. "Marijuana" refers specifically to the dried leaves and flowering tops or "herbal cannabis”, the natural form of cannabis as derived from the plant Cannabis sativa. Another term for marijuana is the word cannabis or hemp.

Biobased composites were successfully prepared using raw materials derived from biomass waste, i.e., an epoxy resin obtained cardanol and nanocellulose unbleached hemp fibers. The by solvent exchange impregnation of the cellulosic mat with resin, followed photocuring. Quantitative conversion was obtained, despite high amount fibers (30 wt%) their absorbance in UV region light spectrum. X-ray di...

A hybrid multicriteria decision-making (MCDM) framework, namely “criteria importance through inter-criteria correlation-combinative distance-based assessment” (CRITIC-CODAS) is introduced to rank automotive brake friction composite materials based on their physical and tribological properties. The ranking analysis was performed ten material alternatives that contained varying proportions (5% 10...

Global environmental concerns, as well the rapid depletion of non-renewable fossil fuel-based resources, have prompted research into development sustainable, environmentally friendly, and biodegradable materials for use in a variety high-end applications. To mitigate setbacks caused by nonbiodegradable materials, biocomposites with improved mechanical performance is gradually gaining momentum. ...

The paper presents the study of polymer composites on epoxy resin matrix, polymerized in environment a constant magnetic field. contained admixtures various forms cellulose – microcrystalline and from waste hemp straw fibers an amount ranging 10 to 30 wt%. Changes mechanical properties due effect field with induction value B = 0.5 T. additionally particles form carbonyl iron,

Abstract Advanced sandwich composite structures that incorporate foams or honeycombs as core materials, have been extensively investigated and used in various applications. One of the major limitations conventional materials is their weak impact resistance end-of-life recyclability overall sustainability. This paper focused on study production mechanical characterization hybrid panels using hem...

Nowadays most plant textiles used for clothing and household are made of cotton and viscose. Before the 19th century however, plant textiles were mainly made from locally available raw materials, in Scandinavia these were: nettle, hemp and flax. It is generally believed that in Viking and early Middle Ages Scandinavia hemp was used only for coarse textiles (i.e. rope and sailcloth). Here we pre...
