Implementation and Characterization of a Hybrid Composite Material with Two Particles of the Same Size: Coco Shells and Palm Shells | Chapter 6 | Current Perspectives on Chemical Sciences Vol. 10

 The goal of this research is to create and analyse a hybrid composite material made up of two identically sized particles. The hulls of palm nuts and coconut are used as reinforcing particles. Molding hybrid composite material composites in the form of specimens at 10%, 20%, and 30% mass fractions in various sizes produced hybrid composite material composites in the form of specimens (0.63 mm, 1.25 mm and 2.5 mm). The samples were mechanically characterised (water absorption rate, moisture content, real, theoretical, and apparent density) as well as physically described (water absorption rate, moisture content, actual, theoretical, and apparent density). The primary findings are that the maximum and lowest water absorption rates are 3.57 percent and 0.67 percent for particle sizes 1.25 mm (sample P10C30) and 0.67 percent for particle sizes 0.63 mm, respectively (sample P10C10). The moisture content of the P20C20 (2.5 mm) and P10C30 (2.5 mm) samples ranges from 0.64 to 7.14 percent, respectively. The greatest and minimum actual densities for composites with particle sizes of 1.25 mm (P20C10) and 0.63 mm, respectively, are 1340,518 Kg/m3 and 1055.981 Kg/m3 (sample P20C20). The actual density at its lowest point is The maximum theoretical density (for samples P20C10, P10C10, and P30C10) is 1194.949 Kg/m3, but the minimum is 1189.966 Kg/m3 (P10C20 and P20C20). The bulk density ranges from 933.28 Kg/m3 to 1176.1 Kg/m3 in diameters ranging from 2.5 mm (P10C30) to 0.63 mm, respectively (for P10C30). The Modulus of Elasticity (MOE) of the samples P10C10 (1.25 mm) and P10C20 (2.75 mm) varies from 25.664 GPa to 25.759 GPa, respectively, in terms of mechanical properties (2.5 mm). Whatever the particle size distribution, the MOE values describe a parabola whose peak is attained when the palm shell loads are 20%, i.e. P20C10. To verify the principles of Hall-law, Petch's samples with microscopic particles are more resilient, with a maximum value of 22.49 J/cm2 and a minimum value of 4.45 J/cm2.
