Abstract:
The study evaluates various mechanical properties of composite materials,
such as modulus of elasticity, tensile strength, and elongation at break, using
tensile, compression, and bending tests. It also investigates vibration damping
capacity and water absorption/loss. Composite laminates comprise multiple
layers engineered to achieve specific mechanical characteristics, including
in-plane stiffness and thermal expansion coefficients. Understanding these
properties is essential for assessing a material’s suitability for different
applications.
The paper identifies two main failure mechanisms during low-velocity
impact (LVI): intralaminar damage, which occurs within the composite
layers (e.g., fiber and matrix failures), and interlaminar damage, notably
delamination. The properties of composites are influenced by several factors,
including the characteristics of constituent materials (including additives),
fiber length, orientation, cross-sectional shape, fiber distribution, and the
volume fractions of the fiber and matrix materials.
