Application Focus Areas
Automotive Powertrain Components
Exceptional stiffness and thermal stability (HDT 208 °C) enable reliable performance in engine brackets, timing chain covers, and transmission housings – replacing metal with significant weight reduction without compromising durability under sustained thermal‑mechanical stress.
Aerospace & UAV Structures
Ultra‑high modulus and low density deliver critical weight savings in drone arms, landing gear struts, and fuselage reinforcement frames, enhancing flight endurance and structural integrity under dynamic loading.
Precision Industrial Gearing
High flexural modulus and excellent creep resistance ensure precise gear tooth geometry, reduced wear, and extended service life in heavy‑duty transmission and conveyor systems.
Robotics & Automation End‑Effectors
A combination of high stiffness, low moisture absorption, and dimensional stability ensures consistent positioning accuracy in robotic grippers, tool changers, and sensor mounts under varying environmental conditions.
Q: What makes PA6 LCF40 different from standard PA6 GF40?
A: Unlike conventional short‑glass compounds, PA6‑BC04A uses 40% long carbon fibers that remain continuous within the pellet. This unique architecture delivers significantly higher tensile modulus (30,998 MPa vs. ~15,000 MPa for short‑glass PA6‑GF40), better creep resistance, and superior thermal stability – enabling thinner‑wall designs and direct metal replacement in highly loaded applications.
Q: Can PA6 LCF40 be processed on standard injection molding machines?
A: Yes. PA6‑BC04A is designed for conventional injection molding equipment. However, due to the high carbon fiber content, we recommend using a low‑shear screw design (18:1–24:1 L/D ratio), free‑flow check valve, and large‑diameter nozzle to preserve fiber length and achieve optimal mechanical properties.
Q: What are the key processing considerations for PA6 LCF40?
A: Critical factors include: thorough pre‑drying to below 0.05% moisture content to prevent hydrolysis, maintaining melt temperature between 243–270 °C to avoid carbonization, using mold temperatures of 54–95 °C for optimal surface finish and dimensional stability, and minimizing residence time to prevent thermal degradation of the carbon fiber‑matrix interface.
