“…Composite materials are widely used today in numerous applications in many engineering fields. 5,6 Many factors affect the properties of composite materials reinforced by natural fibers, which include the geometry, the properties of the different phases (matrix and fibers), the distribution and orientation of fibers with in the medium, the contact between the fibers and matrix, 7 the shape and size of the fibers, the mix design, and the mixing and the processing methods. For the performance predictions of composites, many studies on the composites used only a few significant parameters such as fiber content, fiber length, and fiber type.…”

Due to respect for the environment and the search for more sustainable materials, scientists have started in recent decades to launch studies on bio-composite materials. It is well known that building materials are among the most commonly used materials and have an obvious negative impact on the environment. The development of environmentally friendly composites as insulating materials in buildings offers practical solutions to reduce energy consumption. Therefore, this work presents the use of a new bio-composite material composed of natural fibers, date palm fibers, cement, and sand. In addition, the study on the effect of adding date palm fibers on the thermo-mechanical characteristics of mortars assesses the thermal insulation properties as well as the water absorption and mechanical performance of this new bio-composite material to use it in the construction of buildings. The percentage by weight of date palm fiber in the test samples varied from 0% to 30% for a fiber size of length equal to 7 mm. The characteristics of these samples were determined experimentally in terms of resistance to bending and compression as well as thermal conductivity. The results show that while increasing the weight of date palm fiber, an obviously reduction in thermal conductivity, flexural, and compressive strength of the composite is observed. Hence, date palm fiber has a positive effect on the thermo-mechanical properties of the composite material. Therefore, it considerably improves the insulating capacity of the mortar.

“…In this context, several types of vegetable fibers, including hemp, flax, bamboo, coir, animal hairs, and cork have been combined with different materials, including Portland cement, clay, sand, and gypsum to produce composite materials [7,8]. The properties of composite materials reinforced by natural fibers are influenced by the shape and size of the fibers, distribution and orientation of fibers in the matrix, bond between the fibers and matrix, mixture design, and the mixing efficiency and processing methods [9]. The various investigations carried out on the composites considered only content, length, and type of fiber to evaluate their performance [10].…”

Hygrothermal and Mechanical Behaviors of Fiber Mortar: Comparative Study between Palm and Hemp Fibers

This paper presents an experimental investigation of the hygrothermal and mechanical properties of innovative mortar mixtures reinforced with natural fibers. Fibers extracted from palm stems (PS) and hemp (HF) were evaluated at different percentages. Scanning electron microscope (SEM) observations showed that the PS fibers have rough surfaces and very complex microstructures. Prior to their incorporation into the mortar, the fibers were subjected to different treatments to reduce their hydrophilic character. The employed treatments showed good efficiency in reducing the water absorption of both PS and HF fiber types. Furthermore, the mortar mixtures incorporating these fibers exhibited low thermal conductivity and excellent moisture buffering capacity. Indeed, the moisture buffer value (MBV) of the investigated mixtures ranged between 2.7 [g/(%HR·m2)] and 3.1 [g/(%HR·m2)], hence providing them excellent moisture regulator character. As expected, the fiber mortar mixtures showed very high porosity and low compressive strength ranging between 0.6 and 0.9 MPa after 28 days of age. The low-environmental footprint materials developed in this study are intended for thermal insulation and building filling.

“…Many factors can affect the properties of fibrereinforced composites, including fibre geometry, distribution, orientation, shape and length, as well as, the properties of individual phases (matrix and fibres), contact type, phase mixing ratio and manufacturing, etc. [7]. Most studies found in the literature investigated only a few significant parameters, such as fibre amount, length and type, to estimate composite performance [8].…”

This work investigates the reutilisation of natural (SCB) and modified sugarcane bagasse fibres with aminopropyltriethoxysilane (MSCB) in cementitious composites. The modified fibres were used in the treatment of effluents contaminated with oil-engine. A full factorial design was used to identify the effects of fibre type (natural and modified sugarcane), fibre length (0.6 and 1.2 mm), fibre amount (1 and 2wt%), and fibre condition (before and after oil filtration) on apparent density, water absorption, apparent porosity, ultra-pulse velocity, dynamic modulus, flexural strength and modulus. SCB fibres led to increased apparent density compared to MSCB fibre reinforced composites. The MSCB fibres contributed to reduce the porosity of the composite, leading to higher mechanical properties. The reduced area of MSCB fibres increased the amount of cementitious phase per unit volume which increases the sample strength. Longer fibres (1.2 mm) have a higher surface area, leading to a higher concentration of fibres per unit volume, increasing water absorption by 17%. The amounts of fibres had no significant effect on the mechanical and physical responses. Samples made with 2wt% MSCB fibres of 0.6 mm in length achieved promising results for non-structural applications in civil engineering.
