“…On present market, due to its excellent biocompatibility, mechanical properties and processing properties, polylactic acid (PLA) has gradually become the most representative thermoplastic biodegradable automotive interiors materials, but the expensive cost and brittle character seriously limit its application scope. 1 According to statistics, plastic accounts for 16% weight and 50% volume of new cars. In addition, the main raw material of petroleum-based plastics comes from petroleum, which leads to excessive consumption of petroleum resources and serious plastic pollution.…”

In this study, micro‐nano rice husks (MNRH) fibers are compounded in polylactic acid (PLA) to produce 3D‐printed filaments by using melt blending method, and some properties of the printed samples of different surface treatment processes are measured. Two silane coupling agents of KH550 and KH570 are severally used on MNRH and PLA to mitigate the surface quality deficiencies for an intimate interfacial bond. Microstructural analysis shows that the MNRH fibers of the composites treated by silane coupling agent have a better dispersing performance. Fourier transform infrared illustrates that the KH550 and KH570 are successfully grafted onto PLA and MNRH fibers. Thermogravimetric analysis (TGA/DSC) suggests that the thermostability and crystallinity of the composites treated by silane coupling agents are enhanced. Water absorption experiments shows that the water resistance of the composites is greatly increased by KH550 and KH570. In comparison with pure PLA, the tensile strength, tensile modulus, bending strength and bending modulus of the 6 wt.% MNRH/PLA composites that treated by KH550 and KH570 are enhanced by 83%, 98%, 54%, and 61%, respectively. The composites treated by KH550 and KH570 demonstrates the best performance, suggesting that they have great potential for use as an environmentally friendly alternative material in automotive interiors.

Fiber reinforced polymer (FRP) composites coupons were exposed to real sea environment to assess the influence on the mechanical behavior of composite materials used in the construction of marine structures. Real-life sea environment conditions were opted for instead of the more common simulated and laboratory versions of seawater in the attempt to obtain more realistic structural modeling environmental input design parameters for marine structures. Exposure was performed over prolonged time span instead of the usual accelerated tests. Epoxy and polyester resins, reinforced with glass fibers in three fiber layout configurations, were used to manufacture standardized tensile testing coupons. Mass changes due to seawater absorption, microorganism growth, changes in tensile strength (standard tensile tests), and surface morphology of the coupons were evaluated after 6- and 12-month long periods of submersion in the sea in the Rijeka bay, Croatia. All specimens showed mass increase due to water absorption and growth of attached algae and sea microorganisms. Various levels of reduction in tensile strength, depending on the fiber layout configurations, were observed. Significant changes in the matrix material structure were noticed, effectively producing “voids”. Based on these results, sustainability of FRP composites in marine environment is addressed and discussed.

“…The mechanical behavior of a material, which includes parameters such as tensile strength, elasticity, and thermal conductivity, substantially impacts how it responds to 3D printing [ 16 ]. The raster angle, which determines the orientation of subsequent layers or courses of material deposition, is critical in adequately harnessing various material features [ 13 ].…”

Using the linear elastic finite element method, we investigated how defects significantly influence the integrity of 3D-printed parts made from biodegradable material by experimental techniques and numerical simulations. A defective flaw was incorporated into the tensile test dog-bone sample using Computer-Aided Design and processed by slicing software. Three distinct raster angles examine two sets of samples, one featuring intact specimens and the other with the introduced defects. An open-source 3D printer was used to fabricate both sets of samples, utilizing biodegradable PLA material. In finite element analysis, we employed a highly detailed model that precisely accounted for the geometry and dimensions of the extruded 3D-printed filament, accurately replicating the actual configuration of the 3D-printed samples to an extent. Our study involved a thorough comparative analysis between the experimental results and the FEA simulations. Our findings uncovered a consistent trend for the intact and defective samples under tensile load. Specifically, in the intact case, the samples with a zero-degree raster orientation presented the highest resistance to failure and displayed minimal elongation. Remarkably, these conclusions paralleled our observations of the defective samples as well. Finite element analysis revealed that the stresses, including Principal, Max shear, and Von Mises, were remarkably higher at the 3D-printed samples’ outer surface than the inner layers, reflecting that the failure starts at the outer surface since they exceeded the theoretical values, indicating a significant discrepancy between the simulated and anticipated values.
