Numerical Modeling of the Thermo Mechanical Behavior of a Polymer Reinforced by Horn Fibers

Abstract

The use of bio-loads in the field of composites has become an essential concern for researchers, as opposed to mineral and classical loads that have dangerous effects on the environment. In this work, a tensile test on a virgin material of animal origin was carried out numerically by the finite element method which was able to confirm the experimental tests. The curves from this simulation mainly considered virgin material in a direction parallel to the fiber direction. The results of the numerical modeling have clearly illustrated that the virgin material has a significant Young modulus in the direction parallel to the fiber, which reinforces the assumptions of the anisotropy of the material of animal origin studied and the high rigidity at the direction of the fibers thanks to the keratin that confers this behavior. This bio load has been mixed with polypropylene for different percentages in order to promote the evolution of its thermo mechanical properties. Numerical modeling by the finite elements characterized the studied bio-composite which can find applications in the fields of the automotive, computers, construction and household articles etc.

Thermogravimetric Analysis of Rigid PVC and Animal-Origin Bio-Composite: Experimental Study and Comparative Analysis

“…This methodology numerically determined the mechanical properties of the biomass and bio-composite. Importantly, the results of this numerical model were experimentally validated, reinforcing the credibility of the obtained conclusions [18][19][20].…”

Experimental and Numerical Study of the Mechanical Behavior of Bio-Loaded PVC Subjected to Aging

“…After a tensile test carried out by the EZ-20 tensile machine (figure 4) and a numerical analysis using the finite element method, which is known for its strong ability to predict the behavior of more complex materials [10][11][12][13][14][15][16][17][18][19], on the flexible and rigid PVC samples after and before aging, the results obtained from the test are grouped together in the figures 5 and 6 and table 2. We note that the stiffness of rigid PVC has changed slightly after aging and this is due to the inclination of the slope towards the elastic region.…”

Experimental study of the mechanical effect of bio-loads on PVC recycling

“…Among its waste are the horns (figure 7 below), which are thrown or incinerated in trash cans, with the exception of a small quantity intended for traditional crafts for the manufacture of key chains or decoration products. [8] to [11] Figure 7: Cow horns Also more than 490,000 tons of red meat consumed in Morocco, which implies a large quantity of horns lost or rather wasted in nature. Research engineers began to recycle horns by grinding them into objects through the sintering process.…”
