1. Pointed Impacts A carbon-fiber tube can shrug off a baseball bat but will surrender to an axe. Sharp tips concentrate force into a pin-head area, slipping between the weave’s tows and slicing individual filaments. Once a micro-crack starts, the laminate unzips almost instantly. Guard tubes against dropped tools, metal edges, and flying debris; inspect surfaces after every shift. 2. Extreme Heat Carbon fiber itself tolerates 3,000 °C, yet the surrounding epoxy or PEEK matrix softens far below that. When the resin melts—typically 120–350 °C depending on grade—the tube loses its “glue.” Layers separate, the profile sags, and strength vanishes. Always confirm the resin’s glass-transition temperature before placing tubes near […]

Thermoplastic carbon-fiber composites combine high-strength carbon reinforcements with melt-processable polymers. Yet matching the right fiber format to the right resin—and choosing the best molding route—can make or break part performance. Here is a concise, U.S.-style guide to the five processes that are actually running in factories today. 1. Melt-Impregnated Tape Production Goal: create fully-wetted, unidirectional prepreg tapes for automated lay-up. How it works: tension-controlled fiber tows pass through a molten resin bath, then through heated dies and nip rollers that drive resin into every filament. The key is filament spreading—wider, flatter tows mean faster, more uniform impregnation. Finished tapes are slit to width and spooled for later use. 2. Extrusion-Injection
