Abstract Glass/Biofibers/Epoxy methacrylate of bisphenol-C (G/BF/EBCMAS) sandwich composites was prepared by compression molding. G/BF/EBCMAS showed good mechanical and good to excellent electrical properties and excellent chemical resistance. Studied properties are compared with EBCMAS and G/EBCMAS. In comparison with G/EBCMAS, G/BF/EBCMAS showed considerable decline of tensile strength (18-63.4%), flexural strength (18.8-38.7%), flexural modulus (12.8-50.7%), Izod impact strength (17.4-43.5%), Barcol hardness (2.1-16.7%) and dielectric strength (23.8-76.8%) except flexural strength of G/BM/EBCMAS. G/WC/EBCMAS (96.7%), G/B/EBCMAS (79.2%), G/GN/EBCMAS (83.3%) and G/RH/EBCMAS (97.9%) showed decline of volume resistivity, whereas other sandwich composites showed 1150-58233% improvement. The decrease in mechanical properties and dielectric strength of G/BF/EBCMAS sandwich… More >

Abstract Nowadays, the production of consumer goods is based on the use of non-renewable raw materials, which in recent years has been performing as a problem for the environment. Considering the large number of available biofibers in nature, their use in the development of polymeric composites has inevitably emerged, it is also necessary to take into account the countless discarded plastics that still have the potential to be reused. In this work, fibers were extracted from pineapple crown residues and utilized to compose sustainable composites using recycled polypropylene from cups discarded in the trash as a matrix. However, it is known… More >
