The Macro Fiber Composite™ (MFC) is the leading low-profile actuator and sensor offering high performance, flexibility and reliability in a cost- competitive device. The MFC was invented by NASA in 1999. In 2002, Smart Material started commercializing this invention worldwide as NASA's licensed manufacturer and distributor.

The NASA Macro-Fiber Composite actuator is a flexible piezoelectric composite device designed for controlling vibrations and shape deformations in high performance aerospace structures.

The Macro-Fiber Composite (MFC) actuator is a low-cost piezoelectric device designed for controlling vibration, noise, and deflections in composite structural beams and panels.

2009年3月1日 · Nowadays, lightweight structures with integrated piezoelectric materials Lead Zirconate Titanate (PZT) and Macro Fibre Composite (MFC) used as actuators or sensors have obtained considerable...

In this paper, we present an overview of our most recent work in the development of the NASA MFC actuator device. In particular, we detail results from an extensive engineering properties characterization effort on laboratory reference MFC specimens, and describe our experiences in developing a single-crystal piezoelectric MFC actuator device.

2024年1月1日 · Lead-free piezoceramic macro-fiber composite actuator (MFCA) is successfully fabricated. The lead-free MFCA achieves a comparable or even superior displacement comparing to lead-based counterpart. Large induced displacement with high stable output over 10 5 cycles is achieved by only superimposing a positive dc bias.

MFC (Macro Fiber Composite) is a thin slice piezoelectric composite material with large displacement output and fast response, which can be sticked or embedded in structures easily, so the research on vibration control of beam and plate …

The poling of fibers and in-plane voltage actuation allows the MFC to create the d33 piezoelectric effect, which is stronger than the d31 effect used by the traditional PZT actuators with poling and voltage actuation through the thickness.
