“…Plant fibers as a reinforcing raw material to produce polymer matrix composite materials have gained importance in recent decades due to their low cost, renewable and biodegradable nature, and low density [ 100 , 101 ]. However, the main challenge of utilizing natural fibers as polymeric matrix reinforcing material is the incompatibility between the hydrophilic fibers and the hydrophobic polymeric matrices.…”

Many studies available in the literature focus mainly on the mechanical characterization of fiber, leaving out other physicochemical and thermogravimetric analyses that allow for establishing its potential as an engineering material. This study characterizes fique fiber for its potential use as an engineering material. The fiber’s chemical composition and physical, thermal, mechanical, and textile properties were analyzed. The fiber has a high holocellulose content and low lignin and pectin content, indicating its potential as a natural composite material for various applications. Infrared spectrum analysis revealed characteristic bands associated with multiple functional groups. The fiber had monofilaments with diameters around 10 μm and 200 μm, as determined by AFM and SEM images, respectively. Mechanical testing showed the fiber could resist a maximum stress of 355.07 MPa, with an average maximum strain at which breakage occurs of 8.7%. The textile characterization revealed a linear density range of 16.34 to 38.83 tex, with an average value of 25.54 tex and a regain of 13.67%. Thermal analysis showed that the fiber’s weight decreased by around 5% due to moisture removal in the range of 40 °C to 100 °C, followed by weight loss due to thermal degradation of hemicellulose and glycosidic linkages of cellulose ranging from 250 to 320 °C. These characteristics suggest that fique fiber can be used in industries such as packaging, construction, composites, and automotive, among others.

“…In the natural fiber composite samples, and despite porosities, the amount of fique fibers improved the initial properties of the epoxy matrix because reinforcement makes the material more flexible and resistant. 53 In Guadua, fibers are oriented and aligned naturally in the direction of the axis of growth, and after the thermal process in the furnace, Guadua developed an extremely compact configuration, which improved the impact energies related to the other tested materials. Therefore, the energy absorbed by the Guadua under a temperature profile showed a versatile material that can be used in applications involving impact, and when a low density is required.…”

In this work a natural fiber composite material, the Guadua Angustifolia Kunth from the family of Bamboo is investigated as a suitable alternative for solutions for impact applications, load-bearing, and other structural applications. Since this type of Bamboo grows faster than wood and requires less water and area to reach maturity and be able to crop, it is a competitive, economically, and environmentally solution when is compared to other construction materials. The Bamboo species of interest is a natural one from Colombia and will be evaluated in flexural behavior and under impact response to understand the material subjected under fast loading. Flexural samples were cut parallel to bamboo axial fibers to obtain the highest impact strength. The flexural tests and scanning electron microscopy characterization were included for microstructure analysis. Additionally, compression at high strain rates was characterized by a split-Hopkinson pressure bar (SHPB). Results show flexural strength of about 70 MPa. The impact analysis showed a tough material with very similar values to Charpy notched and dynamic instrumented impact tests.

“…The vast applications of additively printed materials, particularly regarding prototyping, repairs and replacements (Jandt and Sigusch 2009;Bonyar and Santha 2010;Ruamario and Sergio 2019;Zhao and Wang 2017), but also high impact-resistant operations (Roberson and Perez 2015), encourage us to investigate this aspect more deeply. There have been previous investigations on the dynamic properties of resins in general (Sabbagh and Leloup 2002;Whiting and Jacobsen 1980;Jager and Balthazard 2016;Marghalani 2016;Ferracane and Pfeifer 2014), but only during recent years experiments on 3D printing resin-based materials have been reported (Hong and Hu 2021;Rua and Buchely 2019).…”

The usage of resin-based materials for 3D printing applications has been growing over the past decades. In this study, two types of resins, namely a MMA-based resin and an ABS-based tough resin, are subjected to compression tests on a split Hopkinson pressure bar to deduce their dynamic properties under high strain rate loading.Two Hopkinson bar setups are used, the first one is equipped with aluminum bars and the second one with PMMA bars. From the measured strain waves, elastic moduli at high strain rates are derived. Both setups lead to values of $E=3.4$ E = 3.4 –3.8 GPa at a strain rate of about 250 s−1. Numerical simulations support the experiments. Moreover, considering the waves gained from the two different bar setups, PMMA bars appear to be well-suited for testing resin samples and are therefore recommended for such applications.
