Carbon Fiber Knowledge
The latest from the world of advanced composites and carbon fiber technology.
For two decades, the tensile-strength ceiling of commercial carbon fiber climbed in slow, deliberate steps: T300, T700, T800, and in 2019 T1100. Each new rung expanded the range of structures that could be built with polymer composites, and each was reached first by a small group of Jap
T1100-grade carbon fiber sits at the top of the commercial strength range: fibers with tensile strength in the 6,500-7,000 MPa band have historically been supplied by a very small number of producers, and global volume has been modest. On August 4, 2026, Sinofibers announced that it had
Type IV cylinders — fully composite pressure vessels with a polymer liner and a carbon fiber overwrap — are the storage technology of choice for hydrogen fuel-cell trucks, buses, and station cascades. Their defining advantage is weight: a Type IV vessel can be 40 to 70 percent lighter t
Wind blade spar caps are the primary load-carrying members of the blade: long, thick laminates that run from root to tip and resist the flapwise bending loads that dominate turbine operation. As rotor diameters have grown past 100 meters — with blades of 80-90 meters becoming standard f
eVTOL aircraft represent one of the fastest-growing structural applications for carbon fiber composites. A typical four-to-five-passenger airframe carries 100-200 kg of composite structure, and programs now in development expect production rates in the hundreds to thousands of aircraft
T1100-grade carbon fiber — defined by tensile strength in the 6,500-7,000 MPa range — has historically been produced almost exclusively by dry-jet wet spinning (DJWS). The process, in which the spinning dope exits the spinneret through an air gap before entering the coagulation bath, wa
Vitrimer and recyclable resin systems are the most promising answer to the composite industry's end-of-life problem. Carbon fiber composites are valued for their strength-to-weight ratio, but the thermoset matrices that give them structural integrity are permanently crosslinked — once c
ASTM D30 standards for carbon fiber composites define how the industry measures tensile, compressive, shear, flexural, and delamination properties, and how those measurements are reported in datasheets and qualification reports. When a supplier claims a tensile strength of 2,500 MPa, th
AS9100D certification is the entry ticket to the aerospace supply chain. The standard, published by the International Aerospace Quality Group and aligned with ISO 9001, adds aviation-specific requirements for product safety, configuration management, counterfeit part prevention, and spe
