Effect Of Functionalization On Mechanical Properties Of Hybrid Carbon Fiber Reinforced Polymer (Hcfrp) Composite Using Piezopectroscopy

Abstract

Hybrid carbon fiber reinforced polymer (HCFRP) composites filled with alumina nanoparticle reinforcements display improved material properties such as fracture toughness and resistance to crack propagation. However, good dispersion of nanoscale materials in the matrix is important to maximize the improvements in the properties. Uniaxial tensile tests with concurrent digital image correlation (DIC) and piezospectroscopy (PS) were used to quantify the mechanical property and load distribution between the carbon fiber/epoxy and reinforcing nanoparticles. Dispersion and sedimentation of the nanoparticles in the composite are found to have a direct effect on the mechanical behavior of the reinforced composite. Difference in load distribution is identified through the piezospectroscopic measurement of the alumina nanoparticles. The results provide significant quantitative information that help to improve the manufacturing process, to optimize the particle dispersion and, subsequently, the mechanical properties.
