Demo
    A grayscale microscopic image shows a composite material with labeled regions of fibers, matrix, and cracks. The left side offers a wider view, while the right side provides a close-up. Scales: 10 µm and 5 µm.
    The left image is a mathematical simulation created by MultiMech software, and the right is a scanning electron microscope image of the same hardened polymer of carbon fibers and carbon resin. The carbon fibers are round, and the resin is the black or gray in between. Cracks show as white in the left image and black in the right.
    A pair of gray and black mechanical parts, one lying flat while the other is propped up showing its hollow interior and curved edges.
    Ceramic matrix composites (dark gray) make up shroud components of CFM International’s LEAP engines. The white material is an environmental barrier coating.
