Study Explains Strength Gap between Graphene, Carbon Fiber

Carbon fiber, a pillar of strength in materials manufacturing for decades, isn't as good as it could be, but there are ways to improve it, according to Rice University scientists. They found the polymer chains that make up a common carbon fiber are prone to misalign during manufacture, a defect the researchers compared with a faulty zipper that weakens the product.

The Rice lab of theoretical physicist Boris Yakobson set out to analyze these overlooked defects and suggest how they might be curtailed. The lab's work appears this month in Advanced Materials.
