The exploitation of natural fibers to reinforce polymers is a promising practice. Thus, biocomposites have gained increased attention in automotive, construction, and agricultural sectors, among others. present work reports the reinforcement recycled high-density polyethylene (r-HDPE) with hemp afford composite materials as sustainable analogues conventional wood/plastic (WPC) products. HDPE bo...

The effect of chemical treatment of hemp hurds slices in three solutions (EDTA (Ethylenediaminetetraacetic acid), NaOH and Ca(OH)₂) on the properties of natural material was discussed in this paper. Changes in the morphology, chemical composition and structure as well as thermal stability of hemp hurds before and after their modification were investigated by using FTIR (Fourier transform infrar...

Abstract For the last couple of decades, researchers have been trying to explore eco-friendly materials which would significantly reduce dependency on synthetic fibers and their composites. Natural fiber-based composites possess several excellent properties. They are biodegradable, non-abrasive, low cost, lower density, led growing interest in using these industrial applications. However, prope...

to allow cultivation of hemp varieties with a 9–THC content below 0.3%. By 1998 hemp was reintroduced The objective was to study the genetic structure and degree of in practically all of Europe (Bócsa and Karus, 1998), variability of hemp (Cannabis sativa L.) varieties. Six varieties of hemp were analyzed by random amplified polymorphic DNA though in some countries significant resources are sti...

Earthen architecture largely supports the concept of sustainable building. In seismically active area eastern Croatia, there is a large number rammed earth houses, many which are over 100 years old. All these houses were built using empirical knowledge, i.e., without applying national design standards. order to support preservation ethnic villages and traditional field survey was conducted. Par...

This paper presents an optimized washing protocol for as-received natural fibers, prior to large-scale composite manufacturing, the structural strengthening of historic masonry. The aim was achieve a simple standard cleaning fiber surfaces from low molecular weight constituents that may be detrimental towards interfacial strength without damaging fibers. proposed procedure employs application s...

Bio-based products are paving a promising path towards greener future and helping win the fight against climate change global warming mainly caused by fossil fuel consumption. This paper aims at highlighting acoustic, thermal, mechanical properties of hemp-based biocomposite materials. Change in sound absorption as result hemp fibers particle reinforcement discussed this paper. The thermal char...

The article is focused on analyzing the effect of functionalization and reactive processing on the morphological, thermal, rheological and mechanical properties of composites of isotactic polypropylene (PP), polystyrene (PS), poly(ethylene-vinyl acetate) (EVA), with cellulose fibers, hemp or oat as natural fillers. Both polymers and fibers were modified with bi-functional monomers (glycidyl met...

the use of agriculture residues as filler in composites is increasing due to their strength, abundance and low cost. soya stalks show promising renewable natural fiber. in polyethylene composites the physical and mechanical properties (flexural resistance, tensile, impacted absorbed energy, water uptake and thickness swelling) was examined at different composites. the results showed that, the m...

Abstract The composites made of natural and synthetic fiber reinforced materials are getting attentions continuously for different engineering applications. Previously, only fibers were considered the reinforcement due to their superior mechanical properties. However, with span time also gaining popularity sustainable features. pretreatment could enhance thermomechanical performances through im...
