“…[6]. For mineral-based fibers, basalt is generally used as a replacement of dangerous asbestos fibers and probably the only mineral-based fiber type that is available on the market [27]. Furthermore, basalt fiber also has tensile properties close to those of carbon fibers (e.g., for tensile strength, basalt fiber: 1850–4800 MPa and carbon fiber: 3000–5000 MPa) [14].…”

“…Compared with man-made fiber/fabric materials in conventional FRP composites (e.g., E-glass and carbon), plant-based fiber/fabric has a lower price and positive ecological impact [27], but it has lower mechanical properties as it has been mentioned before. In order to balance the performance and the cost for proper material design, several studies have investigated the hybridization of a plant-based fabric with a man-made one in FRP composite [28,29].…”

In this study, the structural behavior of small-scale wood beams externally strengthened with various fiber strengthened polymer (FRP) composites (i.e., flax FRP (FFRP), basalt FRP (BFRP), E-glass FRP (“E” stands for electrical resistance, GFRP) and their hybrid FRP composites (HFRP) with different fiber configurations) were investigated. FRP strengthened wood specimens were tested under bending and the effects of different fiber materials, thicknesses and the layer arrangements of the FRP on the flexural behavior of strengthened wood beams were discussed. The beams strengthened with flax FRP showed a higher flexural loading capacity in comparison to the beams with basalt FRP. Flax FRP provided a comparable enhancement in the maximum load with beams strengthened with glass FRP at the same number of FRP layers. In addition, all the hybrid FRPs (i.e., a combination of flax, basalt and E-glass FRP) in this study exhibited no significant enhancement in load carrying capacity but larger maximum deflection than the single type of FRP composite. It was also found that the failure modes of FRP strengthened beams changed from tensile failure to FRP debonding as their maximum bending load increased.

The usage of composite materials has been growing widely over the years due to their excellent characteristics such as lightweight, high-energy absorption capability and corrosion resistance. In this study, the crashworthiness characteristics of square woven jute/epoxy composite tubes with different configuration of triggering mechanisms were tested and evaluated when subjected to quasi-static axial loading. The deformation morphology of each composite tube was captured by using high-resolution photography. The composite tubes were fabricated by using the combination of hand layup and compression bladder moulding techniques in which total of three layers of woven bi-directional natural jute fabric (plain weave mat) were used, each with wall thickness and length of 3 mm and 100 mm, respectively. To induce the progressive crushing of composite tubes, four different types of triggering mechanisms were used: the non-trigger, single chamfered trigger, double chamfered trigger and tulip trigger. The influence of energy absorption, crush force efficiency, peak load, mean load and load–displacement history was examined and discussed. From this study, most of the composite tubes failed in progressive manner rather than catastrophic failure. Overall, the tulip trigger configuration is considered the optimal design for crashworthy structure applications.

“…However these values of triggered and foam-filled tubes can be larger or smaller than the tubes with foam-filler lonely. In other study, Yan et al [ 14 , 15 ] analyzed how foam filled tubes with more fabric plies exhibited better crashworthiness when compared to the empty tubes, showing that can be comparable to that of conventional aluminum tube and glass/carbon composites tube as energy absorbers. The aim of the following paper is to contribute to a better understand of the crash behavior of natural fiber-reinforced plastics for a better design of the components decreasing their development times and the cost.…”

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 investigated, showing the potential for transport application in energy absorbing structures. Two different woven fabrics (twill and hopsack) made of flax fibers as well as a non-woven mat made of a mixture of hemp and kenaf fibers were employed as reinforcing materials. These reinforcing textiles were impregnated with both HD-PE (high-density polyethylen) and PLA (polylactic acid) matrix, using a continuous compression molding press. The impregnated semi-finished laminates (so-called organic sheets) were thermoformed in a second step to half-tubes that were assembled through vibration-welding process to cylindric crash absorbers. The specimens were loaded by compression to determine the specific energy absorption capacity. Quasi-static test results were compared to dynamic test data obtained on a catapult arrangement. The differences on the specific energies absorption (SEA) as a function of different parameters, such as the wall thickness, the weave material type, the reinforced textiles, and the matrix used, depending on the velocity rate application were quantified. In the case of quasi-static analysis it is observed a 20% increment in the SEA value when wove Hopsack fabric reinforcement is employed. No velocity rate influence from the material was observed on the SEA evaluation at higher speeds used to perform the experiments. The influence of the weave configuration (Hopsack) seems to be more stable against buckling effects at low loading rates with 10% higher SEA values. An increase of SEA level of up to 72% for PLA matrix was observed when compared with HD-PE matrix.
