Carbon Fiber Knowledge
The latest from the world of advanced composites and carbon fiber technology.
Structural adhesive bonding of carbon fiber composites requires careful surface preparation to achieve reliable, durable joints. This article covers surface treatment methods — plasma, corona, peel ply, chemical — and their effects on bond strength and environmental durability.
Ultrasonic phased array testing provides high-resolution imaging of internal defects in carbon fiber composites — delaminations, porosity, fiber waviness, and impact damage. This article covers phased array principles, probe selection, and calibration for CFRP inspection.
Precise temperature control during carbon fiber carbonization determines the final mechanical properties of the fiber. This article covers furnace design, temperature profiling from stabilization through high-temperature carbonization, and process optimization strategies for consistent fiber quality.
PAN oxidation (stabilization) is the most critical and time-consuming step in carbon fiber production, converting thermoplastic PAN precursor into thermoset oxidized PAN that can survive carbonization. This article examines oxidation kinetics, temperature profiling, and process optimization for high-quality carbon fiber.
Carbon fiber composite bogie frames achieve 35-50% mass reduction compared to welded steel while maintaining structural integrity. This article examines manufacturing processes, fatigue performance, and lifecycle cost benefits for high-speed rail and metro applications.
Carbon fiber optical benches achieve near-zero coefficient of thermal expansion (CTE) through quasi-isotropic layup of high-modulus carbon fiber.
Tennis racket frames use a blend of high-modulus and standard-modulus carbon fiber to balance stiffness for power with flexibility for comfort.
Modern badminton rackets use high-modulus carbon fiber with stiffness ratings from 80 to 100+ flex points. This article explains how carbon fiber layup, resin content, and frame geometry affect racket performance.
Carbon fiber trade policy is shaped by national security concerns, anti-dumping duties, and industrial policy. This article maps the current tariff landscape — US Section 232 steel/aluminum tariffs affecting CF products, EU anti-dumping duties on Chinese CF, and emerging trade routes through Turkey and India.
