ASTM D5987 (Guide for the Characterization of Fiber-Reinforced Polymer Matrix Composites)

ASTM D5987 is a standardized guideline used to assess the properties of fiber-reinforced polymer matrices, which are materials made by embedding strong fibers (like glass or carbon) into a plastic-like resin. This guide helps identify key characteristics such as strength, stiffness, and how the material behaves under different conditions. It ensures consistent testing methods, enabling manufacturers and engineers to compare and select suitable composite materials for various applications like aerospace, automotive, or construction, ensuring quality and performance standards are maintained.
