Epoxy resins are widely applied in the automotive and electronic industries. However, pure epoxy resins are brittle and thus possess poor mechanical properties. Herein, we report a facile method for improving the impact-peel and adhesive strengths of epoxy resins via the incorporation of two different types of polyether amines (monoamine-based and diamine-based prepolymers). A comparative study was performed to investigate the potential advantages of incorporating a prepolymer into an epoxy resin matrix. It was discovered that the incorporation of a diamine prepolymer significantly improved th

Nowadays the mechanical properties of epoxy resin used to paste CFRP strengthening the concrete structures, has a sharp drop in more than 60°C. Four CFRP-strengthened concrete one-way slabs were studied in the fire, one using epoxy resin and the other three using inorganic adhesive (Magnesium Oxychloride Cement). The experimental results show that :(a) The fire resistance performance of CFRP-strengthened concrete slab by inorganic adhesive with 15mm thickness fire protection was better than the slab without fire protection; (b) Without considering the impact of burst, the fire resistance perfo

First, tests have been performed with bulk adhesive specimens (epoxy and polyurethane) immersed in water and motor oil during independent periods of time (1 at 128 days) in order to study the diffusion of water and motor oil into the adhesive.

In this study, the effect of bond thickness upon shear strength and fracture toughness of epoxy adhesively bonded joint with dissimilar adherents was addressed. The bond thickness, t between the adherents was controlled to be ranged between 0.1 mm and 1.2 mm. Finite element analyses were also executed by commercial ANSYS 11 code to investigate the stress distributions within the adhesive layer of adhesive joint. As a result, shear strength of adhesive joint reduces with increasing bond thickness. The strength of shear adhesive joint was also depended on elastic modulus of adherent. Moreover, t

In addition to shear strength measurements, the adhesive density profile was also assessed.
