“…The advancement of identical dissimilar components to present conventional metals, artificial materials and their respective alloys have been interesting research in present industrial and academic research investigation throughout the world. [1][2][3][4][5][6][7][8][9][10] Many industries are remunerating more interest to gathering carbon acclaims by decreasing pollutants to the environment. Utilizing natural sources to produce partially or fully biodegradable laminate is one small step against conserving the environment near us.…”

A comprehensive review on natural fillers reinforced polymer composites using fused deposition modeling

Additive manufacturing (AM) is being used more widely because of the simplicity of the operating procedures. It decreases material consumption during part production and eliminates material waste. Fused deposition modeling (FDM), a well‐known AM process, uses thermoplastic polymer as a feedstock to manufacture the end design. Pure thermoplastic‐based products are still utilized as prototypes in several sectors due to their lack of strength and durability. This problem has been solved by strengthening the thermoplastics by adding a reinforcing element. Composites are made of polymers and various constituents known as reinforcing components. This article overviews natural reinforced polymer composites used in the FDM process. Mechanical and Thermal properties are presented based on natural filler percentage, and this article only considered natural composite filaments for the FDM process.

“…This variety is caused by the fiber's source, plant's age, extraction method, and flaws. To address this issue, a two-parameter Weibull distribution was used to analyze natural fiber mechanical properties [21]. By utilizing the Weibull distribution to plot the data, it becomes possible to estimate statistical parameters such as the shape and scale factors.…”

Due to the negative impact of synthetic fibers on the environment, natural fibers are being increasingly used in composite preparation. The hilly area of Uttarakhand state in India has an abundance of pine needle fibers (PNFs). This study focuses on extracting the PNFs using water retting, varying the retting duration (2 weeks, 4 weeks and 6 weeks) and measuring its physical and mechanical properties. After 4-weeks of retting, the extracted PNFs exhibited the lowest moisture content, resulting in improved hydrophobicity and rendering them suitable for reinforcement in composites. The tensile strength and Young’s modulus of the 4-weeks retting PNFs were 52.89 ± 12.77 MPa and 1.48 ± 0.39 GPa, respectively. Mechanical characteristics of extracted fibers have been assessed using Weibull’s statistical method in terms of tensile strength and Young’s modulus. Based on the findings, PNFs are predicted to serve as a reinforcement in environmentally friendly composites.

Adhesives and glass are commonly used in electronic packaging. The macroscopic and microscopic (molecular-level) structures at the interface between glass and epoxy adhesives have attracted a great deal of interest in the field of surface analysis. In many previous studies, sum frequency generation vibration spectroscopy (SFG-VS) with a total internal reflection (TIR) silica prism was used to probe these types of interfaces. However, for adhesives with relatively high refractive indexes, the requirement of a TIR geometry is not matched, and the origin of SFG-VS signals from the interface involving the prism and adhesive is complicated. Many efforts have been made to resolve this issue. This study provides an approach to analyze the linear and nonlinear optical transmission and emission in a silica−epoxy adhesive−silica sandwich sample with different adhesive thicknesses (i.e., 1.5, 4.5, and 13.5 μm). The origin of SFG-VS signals and structural information in the adhesive were revealed from spectroscopy, morphological, and adhesion tests. It was observed that an insufficient adhesive thickness leads to void structures in the adhesive layer, generating a relatively high SFG-VS signal at the adhesive−air interface. However, samples with a filled adhesive layer emit much weaker SFG signals. Lap shear tests, energy-dispersive X-ray imaging, scanning electron microscopy, and SFG-VS with the introduction of liquids into the sample were used to confirm conclusions obtained from linear and nonlinear optical measurements. This study provides a straightforward experimental approach to analyze the relatively complicated interfaces involving polymers.
