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...

Because of their high strength and energy dissipation capacity, aramid fibers are used widely as the material of choice for body armor and similar applications. Their use as reinforcement of concrete panels, whether prestressed or not, poses significant challenges because of their relatively low fiber-to-fiber friction coefficient and limited bond strength between fibers and cementitious matrix...

In this research, an attempt was made to find the permeability of RC beam with AFRP by making use hydraulic conductivity test and a double-ring infiltrometer. Based on state-of-the-art methodology, three different samples, Kelvar 29, 49 149, were considered as laminates prevent deflection beams. Accelerated corrosion carried out using impressed current, induced calculated galvanostatic method. ...

Fiber structures, yarn structures, and mechanical properties of fibers namely tensile modulus, tenacity, and elongation, are the key performance indicators of fabric cut resistance. p-aramid and UHDPE (Ultra High Density Polyethylene) based high performance fibers are most commonly used for protection against mechanical risks. Specially engineered composite yarns and fabrics enhance cut resista...

Introduction In the 1970s, exterior bonded steel reinforcement was used sporadically to reinforce bridges to attain higher service load capacities. This steel post-strengthening system consisted of steel straps bonded with epoxies to the exterior of concrete beams. An alternative to the steel retrofit is woven carbon fiber reinforced polymer fabric applied in the same manner as steel. Carbon fi...

Abstract Hybrid laminates with continuous fiber reinforcement, such as glass reinforced aluminium laminate (GLARE), aramid aluminum (ARALL), or carbon (CARALL), have been developed to increase the lightweight potential and fatigue resistance applied for aircraft structures. However, use of thermosetting matrices imposes material limitations regarding recycling, malleability, manufacturing-cycle...

This paper reports on the synthesis of Cannabis indica fiber-reinforced composites using Urea-Resorcinol-Formaldehyde (URF) as a novel matrix through compression molding technique. The polycondensation between urea, resorcinol, and formaldehyde in different molar ratios was applied to the synthesis of the URF polymer matrix. A thermosetting matrix based composite, reinforced with lignocellulose...

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 ...
