Physical and mechanical performance of natural fiber composites can be tailored by hybridizing with synthetic fibers. Jute fibers are promising highly available at a low cost in some countries, they have been used several applications, the extra benefit helping socially depressed people who commonly explore this plant. This work investigates effect hybridization on properties jute/glass jute/carbon laminates polyester resin. Nine different were manufactured vacuum infusion using...
This paper studies the behavior of S2-glass woven fabric reinforced polymer composite under low-velocity impact at 18–110 J energy. A macro-homogeneous finite element model for prediction their response is implemented, considering non-linear material and intralaminar interlaminar failure modes damage. The accurately predicted permanent indentation caused by impact. By applying Ramberg-Osgood formulation, different initial stiffness values are examined to assess post-impact unloading...
Natural fibres have been partly substituting synthetic in polymer composites due to their renewable character and many other advantages, sometimes, they can be hybridized into a single composite for better combination of properties. This work aims study the effect hybridization stacking sequence on mechanical physical properties glass/jute laminates. For that, pure jute, glass hybrids were manufactured by vacuum infusion process using orthophthalic polyester resin. The characterized via...
Hip joint prosthesis are structural components that still have some challenging problems such as the interaction of physical and biological properties between stem human femur. Composite materials allow to obtain high strength structures with a large variety modulus elasticity favorable characteristics in context orthopedic implants. Therefore, objective this work was development model biopolymeric matrix, namely polyurethane (PU) derived from castor oil, reinforced fiberglass. The implants...
Sandwich panels (SP) are very promising components for structures as they ally high levels of specific stiffness and strength. Civil, marine automotive industries some examples the sectors that use SPs frequently. This work demonstrates potential manufacturing Z-pin-reinforced foam core SPs, using a design strategy indicated optimal values both pin position angle, keeping same diameter determined in previous study. A simple search algorithm was applied to optimize each design, ensuring...
Composites using natural fibers as reinforcement and biodegradable polymers matrix are considered environmentally friendly materials. This paper seeks the mechanical morphological characterization of a biocomposite polyurethane (PU) derived from blend vegetable oils doped with aluminatrihydrate (ATH) reinforced hydrated cotton fiber fabric (HCF). The comparison study were performed based on properties the: (i) pure PU; (ii) PU ATH containing 30% final mass (PU+30%ATH); (iii) composite 7...
This work aims to evaluate the mechanical and flammability behavior of green laminate polymeric composite polyurethane (PU) derived from vegetable oils with reinforcement cotton fiber (CF) unidirectional fabrics added alumina trihydrate (ATH). Specimens PU doped different ATH contents (10%, 20%, 30%) were manufactured by casting process CF/PU composites CFs/PU vacuum bag process, three stacking sequences (fibers oriented on 0°, ± 45°, 90°). Vertical horizontal tests performed, showed a...
