In this review paper, recent developments in the Fused Filament Fabrication (FFF) approach are provided for composite materials. Influencing parameters FFF process such as road width, print speed, layer thickness, feed rate and build temperature of model (both liquefier envelope temperature), fiber orientation, position, volume fraction, infill orientation have been studied. These considered st...

Strengthening of existing circular reinforced concrete columns by CFRP confinement

Reinforced polymers have recently gained interest because of their high stiffness associated with the classical features and cost-effectiveness polymers. A further characteristic, suitable for several applications, is possibility to provide frictional wear resistance. The response commercially available reinforced materials was here investigated in a wide range contact boundary conditions. Expe...

This paper presents the results of a study on the axial compressive strength of columnsstrengthened with FRP wrap. The experimental part of the study included testing 6 reinforcedconcrete columns in two series. The first series comprised three similar circular reinforced concretecolumns strengthened with FRP wrap. The second series consisted of three similar square columns,two with sharp corner...

frps (fiber reinforced polymer) possess many favorable characteristics suitable and applicable for construction industry when compared with steel reinforcement. there are new ideas to use frps as longitudinal or transverse reinforcement for new concrete elements particularly for bridge decks or beams. although high tensile strength of frp is main characteristic for applications at both areas, i...

the creep behavior of basalt fiber reinforced epoxy (bfre) and glass fiber reinforced epoxy (gfre) composites was studied through tensile testing at high temperature. to study the effect of reinforcing epoxy, the micro glass powder (mgp) was added at various volume percentage into the epoxy resin in bfre composites. the initial strain for all the specimens were evaluated and compared with each ...
