Structural composites, which are light weight and exhibit high stiffness and damage tolerance, arouse considerable attention in high-tech applications such as aircraft, satellites, high-speed trains and automotive vehicles. The potentials of these composites are developed by using efficient materials and structural optimization. However, most structural composites are made from metal or fiber-reinforced polymer composites and utilized for high-tech applications with their associated high costs. While the demand for sustainability increases for low-cost common applications, there are unique challenges and opportunities to develop new sustainable composites for light weight engineered materials with a wide range of performance. Thus, it may be possible that bio-composites with efficient structures might sufficiently fill some niche applications for the purpose of substantial development and environmental protection. For this reason, we are working to develop high performance engineered structural bio-composites (ESBs) having improved capabilities. Engineered structural bio-composites (ESBs) with a tri-axial structure core are made from wood-fiber-based laminated papers. These ESB's are not only utilized in building and construction of decks, walls and roofing, but are also applied in container and packaging applications. Moreover, high-strength reinforced fabrics such as carbon fiber or glass fiber fabric are selected for bio-composites reinforcement to meet higher requirements for some high-value applications. The benefits of ESBs, including low density, high strength, fire resistance, water repellency and thermal insulation, are achieved based on various material combinations and design configuration. These green and sustainable (ESB) materials are expected to have huge potential markets and applications. This research presents a systematic analysis of ESB panels made from phenolic impregnated laminate paper composites with different configurations. The design of ESB panels is very flexible to efficiently meet the different requirements for various applications. The panels are assembled using a bonded face-core system. The ribbed core is tri-axial oriented, utilizing a novel fastening configuration of slots in the faces and tabs of the core rib structure to enhance the interface strength. Thermal insulation materials such as self-expanding urethane foam can be selectively used to fill the space between tri-axial ribs for improving insulation properties. This project consisted of three phases. For the first phase, the strength, buckling mode and damage tolerance of ESB with different configurations were initially investigated using compression tests. The different variables and behaviors were analyzed and discussed through the flatwise and edgewise compressions. In the second phase, the static mechanical performances and behaviors of ESB panels with different sizes and configurations were analyzed using bending tests. Twelve strain gages, including normal strain gages and shear strain gages, were attached in each type of ESB panel for analyzing the interior strain distributions in bending. Based on the experimental results, new, simplified orthogonal models, with or without core shear effect of equivalent element, were developed to analyze the mechanical performances of these ESB panels. This was accomplished by transferring repeatable elements of the tri-axial ribbed core and incorporating different laminate plate theories in comparison with finite element model (FEM) and a simple I-beam equation. The analytical results showed that the simplified orthogonal models had good agreement with the experimental data. Then, a new balanced design method was built to fully make use of constituent materials for the ESB panels based on the simplified orthogonal model and FEM simulation. In the third phase, the dynamic mechanical behaviors of the ESB panels were investigated using fatigue tests and low velocity impact tests. The mechanical behavior and failure mechanism of fatigue for the ESB panels were then analyzed and discussed throughout the experiments. The experimental results showed that the ESB panels had better fatigue performance than the traditional wood-based structural panels, and the ESB panels with slot and tab configuration significantly increased the fatigue capacity. For low-velocity impact tests, dynamic behaviors of the ESB panels with different configurations were studied. Experimental results showed that the configuration design and the component materials significantly affected low-velocity impact behaviors and capacity. The core with smaller tri-axial structure had better low-velocity impact performance and energy absorption. We also observed that a stiffer face improved the low-velocity impact performance. The optimum performance of panel can be engineered based on the design requirements.
