Simulation of bond strength between matrix and filler of aligned continuous fiber composite in term of friction coefficient

This work presents a new approach which demonstrates that the degree of fiber-matrix bonding can be quantified by means of the friction coefficient, rather than by using a adhesion parameter. ABAQUS finite element analysis software is used to simulate bonding behavior in term of friction coefficient between fiber and matrix of aligned continuous fiber composite. Simulation result shows that Young modulus of the composite increases linearly with the increase of friction coefficient between matrix and fiber. This shows that if the value of Young's modulus of the fiber is far greater than the Young's modulus of the matrix, then the value of Young's modulus of the resulting composite will tend to get closer to the value of Young's modulus of the fiber. It means that the influence of coefficient of friction between the fiber and the matrix is getting insignificant.
