Abstract

Prirodna vlakna privlače posebnu pozornost zbog povoljnih svojstava poput niske cijene, visokog omjera čvrstoće i mase, male gustoće po jedinici volumena, nekorozivnog svojstva te njihovih i razgradivih svojstava. U usporedbi sa sintetičkim vlaknima, prirodna su vlakna često dostupna po niskoj cijeni i uzrokuju manje problema po zdravlje i okoliš ljudima koji proizvode kompozite u usporedbi s kompozitima na bazi staklenih vlakana. Prirodna vlakna mogu se koristiti za razvoj visoko toplinski... More stabilnih i zvučno izolacijskih materijala. Moguće je proizvoditi vrlo izdržljive potrošačke proizvode od prirodnih vlakana koji se lako mogu reciklirati. Međutim, prirodna vlakna obično pokazuju lošu vodonepropusnost, nisku trajnost i slabo međusobno vezivanje što dovodi do gubitka konačnih svojstava kompozita i na kraju otežava njihovu industrijsku upotrebu. Ljudi su se tijekom povijesnih vremena koristili prirodnim vlaknima, no posljednjih godina primjena prirodnih vlakana u polimernim kompozitima povećala se zbog njihove dostupnosti kao obnovljivih materijala i povećane zabrinutosti za okoliš.

Abstract (english)

Natural fibers have numerous benefits due to their favorable properties, such as: very favorable price, extremely high strength ratio, low density, not subject to corrosion and have excellent degradable properties. If we compare natural fibers, for example, with synthetic fibers, natural fibers are generally available at an extremely affordable price and natural fibers cause much less problems for health and the environment, and are especially harmless to people involved in the production... More of composites as opposed to composites made using glass. fibers. Natural fibers can be used for the purpose of developing thermal as well as sound insulation materials. It is also possible to produce extremely durable consumer products from natural fibers that are very easy to recycle, which is extremely socially acceptable. However, natural fibers also have their drawbacks, and show poor water resistance, low durability and poor interconnection, which results in the loss of the final properties of the composite and ultimately complicates their use in the production process. In recent years, the use of natural fibers in composites has seen an increase due to their advantages as renewable materials and ubiquitous environmental concerns. Less
