Special Issue Information

Dear Colleagues,

In recent years, composites have evolved multifold due to demands from automotive, marine, aerospace, space and defense sectors. The limits have been pushed in regard to the application requirements of constituent elements, symmetric and asymmetric, utilized in different matrices (polymers, metals, ceramics, etc.) and combinations thereof in, addition to different scales (nano to macro). Innovative surface modification approaches of growing nano-scale fibers on micro-scale reinforcements allows for these symmetric and asymmetric composites to exhibit unique sets of properties. Further, different modelling approaches help to predict the resulting properties prior to conducting expensive, tedious and time-consuming experimentations. Machine learning approaches are also quite extensively used currently for predicting composite target values based on available data. Composites can vary based on the processing methodology adopted and, hence, require detailed attention when choosing suitable/appropriate processing parameters with an aim towards minimizing inherent defects. The geometry/size limitations conventional manufacturing poses can be effectively addressed with advanced processing technologies, such as in additive manufacturing, wherein integrated and geometrically complex components can be realized through the minimization of material consumptions. The choice of manufacturing depends on the application, the complexity of the shape and the target properties required. The simulation of composite processes is also practiced to identify gray areas. The aim of this Special Issue is to explore advances in composite materials and structures (symmetric and asymmetric), with a specific focus on the processing, properties and applications in order to provide a consolidated basis for improved modelling, design and manufacturing. Original research works and review articles related to advances in composite materials and structures are encouraged.

The fiber-filled polymer composite is one of the best materials which provides a symmetrical superior strength and stiffness to structures. With the strengthening of people’s environmental protection and resource reuse consciousness, the development of renewable materials, especially natural fiber-filled polymer composites, is receiving great attention. This study investigated the mechanical properties of polymer composites incorporating waste materials from the food processing industry and agricultural sources. Waste vegetal fiber-filled polymer biocomposites (WVFFPBs) with varying fiber types and 3D printing orientations were systematically fabricated. Subsequently, the tensile tests were executed to comprehensively assess the anisotropic mechanical behaviors of the WVFFPBs. The results demonstrated that WVFFPBs performed excellent anisotropic mechanical properties compared to pristine matrix samples as print orientation changed. As the printing angle increased from 0° to 90°, the tensile mechanical properties of the WVFFPBs displayed a decreasing trend. Moreover, the print orientation–anisotropic mechanical behavior relationship of 3D-printed WVFFPBs was revealed through the analysis of the material manufacturing characteristics and damage features.
