“…Few works in the literature aim to compare the mechanical properties between composite laminates made with epoxy and bio-based epoxy resins. Yashas Gowda et al [ 18 ] compared the mechanical properties of a laminate made of hybrid basalt and areca fibers. Tensile tests and flexural tests showed a decrease of ~5% for the tensile and flexural strengths and tensile and flexural moduli for the composites prepared with bio-based epoxy resin.…”

In recent years, interest in sustainability has significantly increased in many industrial sectors. Sustainability can be achieved with both lightweight design and eco-friendly manufacturing processes. For example, concerns on the use of thermoset composite materials, with a lightweight design and a high specific strength, have arisen, since thermoset resins are not fully recyclable and are mainly petrol based. A possible solution to this issue is the replacement of the thermoset matrix with a recyclable or renewable matrix, such as bio-based resin. However, the mechanical properties of composites made with bio-based resin should be carefully experimentally assessed to guarantee a safe design and the structural integrity of the components. In this work, the quasi-static mechanical properties of composite specimens (eight layers of carbon fiber fabric) made with commercially available epoxy and a bio-based epoxy resins (31% bio content) are compared. Tensile tests on the investigated resins and tensile, compression, shear and flexural tests have been carried out on composite laminates manufactured with the two investigated resins. A finite element model has been calibrated in the LS-Dyna environment using the experimentally assessed mechanical properties. The experimental results have proven that the two composites showed similar quasi-static properties, proving that bio-based composite materials can be reliably employed as a substitute for epoxy resins without affecting the structural integrity of the component but lowering their carbon footprint.

In recent years, awareness on environmental issues has led to development of biobased materials for a variety of engineering structural applications. Nowadays, researchers and scientists are focusing their efforts on the development of sustainable materials that make use of readily available, renewable, and biodegradable natural resources. While significant progress has been made in the study of hybrid fiber reinforced composites, the fundamental problem of incorporating and selecting the optimal combination of reinforced fibers for various applications has not been adequately addressed. Hence present study addresses the use of combination of two natural fibers with different synthetic fibers to assess the performance of the hybrid fibers composites to develop for engineering applications. In present work the effect of stacking sequence on the mechanical and thermal property of the flax, kevlar, carbon and carbon‐kevlar hybrid fiber reinforced epoxy composites are studied. The four layered composite laminates with different stacking sequence were fabricated using hand layup technique to study the mechanical properties such as tensile, flexural, interlaminar shear, and impact tests, thermal behavior, water absorption, contact angle measurement and scanning electron microscopy. The hybrid carbon/flax composite (CFFC) had better strength as compared to KFFC, HFFC, and FFFF composite laminates with better tensile strength (178.48 MPa), tensile modulus (2132 MPa), flexural strength (378.86 MPa), flexural modulus (15.76 GPa) and interlaminar shear strength (13.91 MPa) and impact strength (13.86 MPa) and water absorption behavior. The stacking sequence revealed that the hybridization of the flax with the synthetic fiber enhanced the properties as compared to the pure flax composites. The influence of the synthetic fibers at outer skin layer had the effect on enhancing the properties of composites. From the obtained results we can effectively utilize the hybrid flax fibers in some various lightweight engineering applications.

Bio-epoxy composites containing boron nitride (BN) particles with different size and shape (0D spherical micro-and nanoparticles, 1D nanotubes (T), and 2D nanosheets (S)) are prepared and revealed appropriate thermal conductivity, thermal stability, and mechanical properties. Systems containing one or two BN nanoparticles showed evenly dispersed structures because of applying high-shear, ultrasonic, or combination of these methods. Microscopic analysis proved that high-shear assisted ultrasonic technique ended up in an homogeneously dispersed BN nanoparticles in the epoxy matrix. The combination of platelet-like and tubular nanoparticles synergistically enhanced both the thermal stability and thermal conductivity of epoxy. Differential scanning calorimetry (DSC) thermographs appeared a sharp peak demonstrating excessive thermal energy released because of network formation of BN conductive fillers. The bi-oepoxy containing equal weight fractions of T and S (1:1 w/w ratio) showed the highest thermal conductivity and tensile strength values of 2.21 W/m.K and 80 MPa, respectively. In conclusion, properties of epoxy nanocomposites are affected by the filler network formation, such that conductive incorporation of 3 wt.% of BN platelet-like and nanotubes increased thermal conductivity up to 1400% and mechanical properties up to 50% with respect to the neat epoxy.
