Adhesion Improvement of Bio‐Based Epoxy in Environmentally Friendly and High‐Performance Natural Fiber‐Reinforced Composites

چکیده
Developing robust bio-based epoxy against petroleum-derived is necessary for environmentally friendly and high-performance natural fiber-reinforced composites. A vanillin (VE) synthesized from the lignin-derived vanillin, a thermoset resin prepared after mixing it with 4,4′-diaminodiphenyl methane (DDM) hardener. Further, infused in high-cellulose-containing alkali-treated jute fiber (TJF) mats through simple approach to enhance adhesion between VE-DDM TJF. Bio-based shows better compatibility TJF than bisphenol diglycidyl ether (DGEBA) epoxy. The VE-DDM/TJF composite demonstrates Tgis ≈165 °C, tensile strength ≈83.12 ± 3.80 MPa, Young's modulus ≈2.86 0.10 GPa excellent flexural (138.72 3.81 MPa) (8.01 0.11 GPa). It also merits regarding hydrophobicity, reduced water absorption ability, durability, chemical resistance an acidic medium. VE composites pave way produce structural applications.

In this study, acrylated soybean oil (AESO) was used as modifying agent for DGEBF-type epoxy resin (ER). AESO was used as a co-matrix in 50 wt % with ER. Composites with ecofriendly natural fillers-banana bark and seashell were prepared. MNA was used as a hardener. Effect of banana peel (BP) and seashell (SSh) fillers on mechanical properties, such as tensile strength, elongation at break, and ...

Carbon fiber-synthetic foam core sandwich composites are widely used for many structural applications due to their superior mechanical performance and low weight. Unfortunately these structures typically have very poor acoustic performance. There is increasingly growing demand in mitigating this noise issue in sandwich composite structures. This study shows that marrying carbon fiber composites...

" Environmentally Friendly " Way!
We discuss how to implement an " environmentally friendly " renormalization in the context of finite temperature field theory. Environmentally friendly renormalization provides a method for interpolating between the different effective field theories which characterize different asymptotic regimes. We give explicit two loop Padé resummed results for λφ 4 theory for T > T c. We examine the impli...
