Segmentation by type classifies glass‑like carbon into isotropic, anisotropic, woven, non‑woven, and composite forms, each defined by fiber orientation and manufacturing process. Isotropic grades exhibit uniform properties in all directions, making them suitable for general‑purpose seals and gaskets. Anisotropic variants, engineered with aligned fibers, deliver superior strength‑to‑weight ratios for aerospace and high‑performance automotive parts. Woven structures consist of interlaced carbon fibers, offering enhanced dimensional stability for electronic substrates. Non‑woven types, produced through felting or matting, provide porous architectures advantageous in filtration and catalyst support. Composite forms integrate glass‑like carbon with polymers or ceramics to tailor thermal conductivity, electrical resistance, or mechanical rigidity for specialized medical implants and industrial tooling. While type‑based segmentation does not directly feed into the pie‑chart, it refines the overall market taxonomy by mapping material characteristics to the application segments outlined above.
