Introduction

With the continuous development of modern industry, the demand for high-performance materials has grown increasingly urgent. Among these, benzoxazine (BMI)-modified ultraviolet (UV)-curable resins, as a new type of composite material, have garnered significant attention due to their excellent properties.
