 A hybrid material made of synthetic and vegetable fibers in a polyester matrix can substitute pure glass composites depending on the application, and its dynamical mechanical properties should be analyzed to understand the structure-property relationship. The study of various cure or glass interlaminar hybrid composites showed that higher hardness was observed when glass fiber was near the surface being tested, and the presence of two consecutive glass layers yielded competitive impact properties in comparison with pure glass composite. The dynamic mechanical analysis revealed that the pure glass composite had the highest storage modulus values, followed by G2, C2, S, while pure cure or yielded the lowest values. Higher dissipation energy was found for the G2, C2, S composite due to the four cure or layers grouped near the midplane. The higher glass transition temperature and the largest turn delta peak height and peak width at half height were found for the pure glass composite.
