Effect of curing temperature and layering pattern on performance studies: a novel hybrid composite

The effect of curing temperature and layering pattern on mechanical and free vibrational properties (natural frequency and damping) of Sansevieria cylindrica/coconut sheath fiber reinforced hybrid unsaturated polyester (USP) composites is discussed. The hybrid composites were compression molded using different layering sequences. Curing was carried out at different temperatures (30 degrees C and 60 degrees C). The results show that Sansevieria cylindrica/USP composites are stronger than the coconut sheath/USP composites. At higher curing temperatures, a significant improvement in strength was observed in all composites and layering pattern also played a vital role in enhancing composite strength, with coconut sheath/Sansevieria cylindrica/Sansevieria cylindrica stack yielding a higher strength compared to the other composites. In addition, curing temperature and layering pattern produced a similar effect on the vibrational characteristics of the composites.
