WebMay 1, 2024 · Crystallinity Deformation Mechanical properties 1. Introduction Short-carbon-fiber-reinforced polyether ether ketone (CF/PEEK) composites are high-performance polymers with excellent mechanical strength, thermal stability, chemical corrosion resistance, and creep resistance. Crystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In an ideal gas, the relative positions of the atoms or molecules are completely random. Amorphous materials, such as liquids and glasses, represent an intermediate case, having order over short distances (a few atomic or molecular spacings) but n…
