Commercially available snack bars and other foodstuffs prepared from pressed hemp seeds were ingested by volunteers. Urine specimens were collected for 24 h after ingestion of the foodstuffs containing hemp seeds and tested for marijuana using an EMIT immunoassay and gas chromatography-mass spectrometry (GC-MS). Specimens from individuals who ate one hemp seed bar demonstrated little marijuana ...

Natural fibers are available in low cost, easily renewable and they rich cellulose. As the natural possess impurities over surface, poor wettability interfacial bonding main drawbacks encountered during fabrication process. In current research work, hemp (H) palmyra (P) were treated with different sodium hydroxide (NaOH) concentrations (2%, 4%, 6%, 8%) for 5 hrat room temperature. The influence...

The study of natural fiber reinforcement composite structures has focused the attention of the automobile industry due to the new regulation in relation to the recyclability and the reusability of the materials preserving and/or improving the mechanical characteristics. The influence of different parameters on the material behavior of natural fiber reinforced plastic structures has been investi...

This paper presents the outcomes from an extensive investigation on the structure and geometry of single hemp fibres, as well as configurations and related tensile strength (TS) of hemp fibres, with the aid of field emission scanning and optical microscopy. The results showed that 1) the TS increased with the decrease of the diameter of individual test pieces, due possibly to the stacks of mult...

Effect of addition of filler material to the natural fiber composite was experimentally investigated. Composites are manufactured by the conventional hand-layup method. All composites are made with a fixed banana fiber with 15% weight fraction addition of different weight fraction of (0, 3, 5, 7.5%) groundnut shell ash is added to the composite. Tensile, hardness, impact and compressive strengt...

The composite group investigates endlessly the features of natural fiber/thermoplastic matrix materials to improve recyclability, use renewable sources, and reduce material costs. In this context, development biodegradable polymers for composites is considered one important strategies reducing environmental challenges. Here, axially oriented fibers incorporated in conforming matrices make up fi...
