Abstract

Thermosetting bismaleimide (BMI) resin and its composites have been widely used in the aerospace field, but the design and preparation of BMI composites with integrated structure and function still remains a challenge. Herein, a series of fluorine bismaleimide (FBMI) resins were synthesized using 2,2′-bis(trifluoromethyl)-4,4′-diaminobiphenyl (TFMB) and 4,4′-diphenylmethane bismaleimide as the monomers, and the flexible piezoelectric sensors were fabricated by compounding it with glass fiber fabrics (GF). The fabricated films demonstrate exceptional thermal stability with a Td5% value up to 440?°C. Moreover, the tensile strength and modulus of composite films are mainly in the range of 160?~?256?MPa and 3.55?~?5.29 GPa, respectively. Remarkably, the FBMI-GF exhibits outstanding piezoelectric properties with an output voltage reaching 4?V. In particular, the fabricated piezoelectric sensor FBMI-50 demonstrates the most optimal piezoelectric performance with a short response time of 40?ms. Furthermore, the sensor exhibits outstanding capability of detecting different motion states of the human body with stable output voltage (3?V) after 5000 working cycles, indicating excellent stability and durability. This study firstly reported the piezoelectric property of the BMI composites and provides a novel candidate for the fabrication of structure–function integrated composites in aerospace and microelectronic fields.
