In this paper, a new type of flame retardant (AF‐Fe) based on para‐aramid fiber (AF) which was modified with iron diethyl phosphinate was applied for thermoplastic polyurethane elastomer (TPU). The flame‐retardant properties of TPU were tested using cone calorimeter test, smoke density test, and thermogravimetric analysis/infrared spectrometry. The cone calorimeter test showed that AF‐Fe can greatly reduce the heat release rate, total heat release, smoke factor, and other parameters of TPU composites compared with the sample of TPU/AF. For example, the pHRR of the composite with 1.0 wt% AF‐Fe was reduced by 15.19% compared with the sample with the same content of pure AF. In addition, the smoke factor of TPU/AFFe3 was reduced by 50.52% and 15.63% compared with TPU0 and TPU/AF respectively. The results of smoke density test showed that the luminous flux of TPU/AFFe3 was increased by 79.26% compared with the sample of TPU/AF. The TG results revealed that the sample with TPU/AFFe3 had lower weight loss rate and higher char residue content at 700°C compared with the sample of TPU/AF.

Commercial concrete samples, tested under three-point-bending (3PB) test, are repaired with adhesive epoxy joint. Short Kevlar fiber is used together with the epoxy and hardener mixed resin to improve the fracture performance. Two different repairing methods are used, (a) with epoxy only, (b) with epoxy and short Kevlar fiber of 6 mm, and the experimental results of failure peak load are compared. The fracture energy is also measured. The short Kevlar fiber bridges the concrete fracture surfaces and epoxy joints, which requests a higher peak load or fracture energy. The interfacial fracture mechanism also alters because of the short Kevlar fiber. The fracture mechanisms of the concrete samples before and after repaired with the adhesive joint and Kevlar fiber are discussed.

“…Exist studies confirmed that, the long term structural performance of structures reinforced by the carbon-fiber plastic is influenced by potential interfacial fatigue and delamination. Recently, a new method to improve the interfacial toughness and strength of sandwich structures was proposed by applying short aramid-fiber mat between aluminum foam and carbon-fiber cloth [4,5]. Improvement in both Mode-I and II interfacial toughness and strength under quasi-static and impacting load were observed [6][7][8][9] due to the bridging effects ________________________ Shun Wang, Xiaofei Zhang*, School of Architecture and Engineering, Shenyang University, No.…”

The interfacial fracture and delamination mechanism of a concrete beam reinforced by carbon-fiber reinforced plastic was investigated in this study. Short aramid fiber mats were applied between the carbon-fiber cloth and concrete to improve the interfacial toughness. Four-point bending tests (FPB) were carried out to determine measure the critical strain energy release rate. By testing specimen with different amount of carbon-fiber cloth and aramid-fiber mat, the thickness influence was also investigated. SEM image of the splitting fibers explains the enhancement of the critical energy release rate the enhancement of the critical energy release rate was studied by EM image of the splitting fibers. The critical energy release rate of the interfacial delamination was also evaluated through the Finite element analysis (FEA) simulation and was used to verify the experimental result.
