Abstract In this paper, knitted aramid fiber (AF) was used as the support, and graphene oxide (GO) was loaded on the support by the polydopamine (PDA) method. Epoxy resin (EP) was poured to obtain composite materials. The tribological and mechanical properties of the composites were tested, and the wear surface of the composites was characterized by scanning electron microscopy (SEM) and three-dimensional morphology. The results show that knitted AF can markedly improve the mechanical properties of the composites. As a two-dimensional material, GO plays an effective lubrication role, and GO effectively enhances the tribological properties of… More >

Abstract This study investigates the potential of Tin Slag Polymer Concrete (TSPC) strengthening through confinement using basalt fiber reinforced polymer (BFRP) and aramid fiber reinforced polymer (AFRP) confinement. TSPC short cylindrical column samples have been wrapped with BFRP and AFRP in a single layer (30 mm overlap) using Sikadur-330 epoxy and final samples were coded as TSPC-UC, TSPC-BF and TSPC-AF for unconfined, BFRP and AFRP for confined respectively. After curing for 30 days at room temperature, compressive test has been performed to know the strength, modulus, strain, fracture energy and failure modes of unconfined and confined… More >
