“…According to the study carried out on jute fibre-reinforced polymer composites, increasing the percentage of fibres in the composite leads to low thermal conductivity. Increasing the percentage of fibres implicitly increases the density of the composite, resulting in increased contacts between fibres, which explains the low values of thermal conductivity [ 45 ].…”

The aim of this paper is to propose ecological thermal insulation materials that meet the goals of sustainability but also fulfill the imposed thermal performance requirements. This paper studies new composite materials based on sheep wool from the perspective of thermal conductivity. The composites were prepared using two types of binder: acrylic-polyurethane resin and natural rubber latex, which were applied to the wool fibres through different methods and percentages. Based on the obtained results of thermal conductivity, two types of samples were selected for further analysis, which aimed to determine the microstructure, chemical composition, water absorption, attack of microorganisms, water vapour permeability, hygrothermal adsorption characteristics and sound absorption of the samples. In order to analyse the variation of thermal conductivity, the following parameters were taken into account: thickness, density, type of binder and percentage of binder. Following the obtained results, it was observed that the value of the thermal conductivity of the samples varies between 0.0324 and 0.0436 W/mK. It was found that all the samples prepared and analysed in this study fulfil the national criteria for the thermal performance of thermal insulation material. After conducting the in-depth analysis of the two selected sample types, it was concluded that both materials have good sound absorption characteristics over the considered frequency range. In addition, as it was expected from the natural fibres, the samples had low resistance against the attack of microorganisms and water-related tests.

The demand and applications of bolstered plastics such as natural, attainable, biodegradable, and fibres were developing worldwide in industries beginning from home utilities to aerospace applications. The high cost and weight of synthetic fibres were bolstered by a multitude of concerns. Subsequently, it is far vital to create a natural fibre combination with a matrix to accumulate the most efficient common presentation. In this present study, a composite is made of a natural fibre (jute) reinforced with vinyl ester resin with and without a filler (SiO2). Untreated jute fibres are utilised as reinforcement, while filler materials were used to increase the characteristics of jute fibre and analyse the impact of filler material in the composite. The produced composite was tested for tensile strength, compressive strength, flexural strength, and hardness. The SEM study of the fracture surface was also evaluated in the present study. Filler-mixed composites have a 50 percent higher tensile strength than those without fillers, and the remaining attributes have enhanced by at least 5 to 10%. From analysis, filler-mixed composites hold a good mechanical property due to fibre-filler bonding with the help of vinyl ester resin.

“…The natural fibers such as jute, vakka, hemp, sisal, date, coir, bamboo, banana, elephant grass, areca, flax, abaca, pineapple, kenaf, and husk fiber are the extensively used fibers for fabricating the polymer composites. Recently, many research works are going on in this field [1][2][3][4]. For instance, Shibata et al [5] investigated the effect of fiber loading on flexural properties of the unidirectional bamboo and kenaf fiber reinforced composites and the results revealed that the optimum flexural modulus is obtain at 60 vol.% for kenaf fiber and 72 vol.% for bamboo fiber.…”

The use of natural fiber reinforced composites gains attention due to its weight and reasonable strength in the recent years. Generally, the mechanical performance of the hybrid composites are superior than the mono fiber reinforced composites. In this work, two different types of natural fibers, namely hemp and palmyra fibers, are selected as reinforcement materials for the development of unidirectional fiber reinforced hybrid composites. Composite laminate was fabricated with four different weight percentages (10 wt.%, 20 wt.%, 30 wt.% and 40 wt.%) and three different hybrid ratios (1:1, 1:2, and 2:1) of hemp and palmyra. The influence of fiber percentage and stacking sequence on the mechanical performance such as tensile strength, flexural strength, impact energy, and hardness of the hybrid composites was evaluated. From the results, it was observed that the adding 30 wt. % of hemp and palmyra fiber can increase the tensile strength and flexural strength by a percentage of 112% and 241% respectively. The impact energy absorption and the hardness of the hybrid composites are examined and compared. The experimental results shows that the hybrid composites containing high fiber weight percentage contribute to significant increase in impact energy and hardness. Morphological analysis is done using Scanning Electron Microscope (SEM).
