Flax fibers – epoxy with embedded nanocomposite sensors to design lightweight smart bio-composites

Highly extensible bio-nanocomposite fibers.

Here, we show that a poly(ethylene oxide) polymer can be physically cross-linked with silicate nanoparticles (Laponite) to yield highly extensible, bio-nanocomposite fibers that, upon pulling, stretch to extreme lengths and crystallize polymer chains. We find that both, nanometer structures and mechanical properties of the fibers respond to mechanical deformation by exhibiting strain-induced cr...

Characterization of Regenerated Cellulose for Bio-based Epoxy Fibrous Composites

Thermal Degradation of HDPE Short Fibers Reinforced Epoxy Composites

Thermogravimetric analysis was carried out to investigate the thermal degradation of High Density Poly Ethylene (HDPE) short fibers reinforced epoxy composites. Three composites with 5, 10 and 15 % by weight of HDPE short fiber composition were prepared using epoxy as matrix material. The HDPE short fiber used as reinforcing material into the resin helps in retarding the thermal degradation of ...

Ventilator with a capnograph smart sensors

Today, the world has witnessed increasing development in various fields, including industry and medicine. One of the best ways to achieve these objectives is the integration of different sciences including electronics, robotics and medicine. Ventilator set that provides respiratory function for patients get smarter and more capable than older generations, during mechanical ventilation to preven...

hemp, and flax composites

This study characterizes the acoustical behavior of natural fiber composites. Regenerated cellulose fibers (Lyocell), hemp fibers, and flax fibers were embedded in an epoxy-matrix. These unidirectional composites were tested for their logarithmic damping decrement, the resonance frequency, the ultrasound velocity, the dynamic and static modulus of elasticity, and bending strength and density. G...
