Wall Panel Made of Bio-composites

Acoustic properties of 3D printed bio-degradable micro-perforated panels made of Corkwood Fiber-Reinforced composites

Introduction: Micro perforated panel (MPP) absorbents promise the next generation of sound absorbers as they have significant advantages over other porous adsorbents. In this study, we will investigate the acoustic performance of MPP absorbents made of biodegradable polylactic acid composite reinforced with natural corkwood fibers (PLA/Corkwood) by 3D printing technology. Material and Methods:...

Bio-based Composites That Mimic the Plant Cell Wall

Wall-crossing made smooth

In D = 4,N = 2 theories on R, the index receives contributions not only from single-particle BPS states, counted by the BPS indices, but also from multi-particle states made of BPS constituents. In a recent work [1], a general formula expressing the index in terms of the BPS indices was proposed, which is smooth across walls of marginal stability and reproduces the expected single-particle cont...

Bio-inspired Ceramic/carbon Composites

Bio-inspired impact-resistant composites.

Through evolutionary processes, biological composites have been optimized to fulfil specific functions. This optimization is exemplified in the mineralized dactyl club of the smashing predator stomatopod (specifically, Odontodactylus scyllarus). This crustacean's club has been designed to withstand the thousands of high-velocity blows that it delivers to its prey. The endocuticle of this multir...
