The objective of this manuscript is to develop, for the first time, a mathematical model prediction buckling, postbuckling, and nonlinear bending imperfect bio-inspired helicoidal composite beams with rotation angle. equilibrium integrodifferential equations (curved) are derived from Euler–Bernoulli kinematic assumption. differential integral quadrature method (DIQM) Newton-iterative employed e...

This study investigated the moldability and mechanical properties of bio-composite with rice husk as natural reinforcement. Natural materials that are abundant in nature can be used reinforcement for polymer materials. plastic were to obtain alternative an injection molding process. With husk, polypropylene, MAPP, four compositions made raw material The from this was observed through visualizat...

The focus of this work is to make a significant contribution solid waste management by designing impact-absorbing bio-composite panels using bio-resin and denim wastes. In context, composite are produced vacuum infusion technique both epoxy acrylated epoxidized soybean oil (AESO) based hybrid resins while wastes utilized as reinforcement materials in fiber fabric forms. Both physical (fiber den...

The marine industry is one of the largest consumers of composite materials. According to Composite Insights, the demand for composite materials in global marine-composites industry is set to grow 5.8% per year between 2013 and 2018 [1]. Given the rising prices of fossil fuels and the increasing global environmental awareness, there is now pressure on the reduction of the use of crude-oil-based ...

Sandwich composites were fabricated successfully with the balsa wood as core material and regenerated cellulose fabric bio-based polypropylene (PP) composite skins. The PP produced using two different methods: conventional stacking lay-up directly pellets. made hot press equipment customized mold. sandwich system bio-composite laminate designed to achieve very close weight compare key mechanica...

Remarkable mechanical properties of biocomposites (bone, teeth, shell, antler etc.) are usually attributed to their special design where staggered mineral platelets are embedded in a protein matrix. Because of the high aspect ratio of the platelet the soft protein deforms in the shear mode predominantly providing the linkage for the hard inclusions. Mimicking Nature one might design materials w...

Abstract This research work is aimed to convert fish scale wastes as an effective reinforcement in polylactic acid (PLA) a new bio-composite filament for fused deposition-based 3D printing applications. Various concentrations of particles (0, 10, 20, and 30%) were used make the filaments. The performance developed filaments was assessed by into various test specimens perform tensile, flexural, ...
