“…V. Yakushin and his fellows have investigated the effect of HGM on the properties of low-density RPUF. 25 They indicated compressive property of RPUF would be enhanced by increase of HGM content. Chalivendra et al 26 found HGM had a great effect on compressive mechanical properties of RPUF, and the presence of HGM with intrinsic low density barely affected the density of HGM/RPUF.…”

Rigid polyurethane foam (RPUF) composites filled with expandable graphite (EG), hollow glass microspheres (HGM), and glass fibers (GF) have been synthesized and characterized by limiting oxygen index, radiation ignition, compressing and torsion testing, and scanning electron microscopy. The results indicate HGM and GF benefit to the mechanical properties, while EG is good for flame retardancy. Proper ingredient of additive can lead to good flame retardancy and mechanical properties of the RPUF. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40253.

“…looked into the flame‐retardancy property of hollow glass microsphere/RPUFs in the presence of expandable graphite, they indicated that when the hollow glass microsphere content arrived at 10 wt %, the compressive strength and modulus of the composites reached a maximum value. Yakushin and coworkers studied properties of RPUFs filled with glass microspheres, and it was established that the filled foam had compressive strength and modulus of elasticity in parallel (foam rise) direction 10%–13% higher than these for neat foam.…”

Some rigid polyurethane foam (RPUF) composites modified with microencapsulated red phosphorus (MRP), magnesium hydrate (Mg(OH)2), glass fiber (GF), and hollow glass bead (HGB) were prepared. The influence of the MRP, Mg(OH)2, GF, and HGB on the flame‐retardant, combustion, and mechanical properties of the filled RPUF composites was investigated. The results showed that the flame‐retardant and the combustion properties of the composites were obviously improved, the limiting oxygen index, half burning time and the residual mass/original mass ratio increased with increasing MRP/Mg(OH)2 weight fraction, especially in case of MRP/Mg(OH)2 weight fraction of 8 wt %; the carbon monoxide (CO) concentration decreased with increasing MRP/Mg(OH)2 weight fraction, When the composites were loaded appreciate content of the HGB and the GF, the maximum torque and compressive strength of the composites were improved. © 2018 Wiley Periodicals, Inc.

“…Yakushin et al investigated the properties of low-density rigid polyurethane foams with hollow glass 2 Shock and Vibration microspheres. The tension and compression properties in relation to the content of microspheres were determined in their work [12]. Alhozaimy et al found that the flexural toughness and impact resistance showed an increase in the presence of polypropylene fibers [13].…”

Researches on blast-resistant measures for underground structures such as tunnels and underground shopping malls are of great importance for their significant role in economic and social development. In this paper, a new blast-resistant method based on wave converters with spring oscillator for underground structures was put forward, so as to convert the shock wave with high frequency and high peak pressure to the periodic stress wave with low frequency and low peak pressure. The conception and calculation process of this new method were introduced. The mechanical characteristics and motion evolution law of wave converters were deduced theoretically. Based on the theoretical deduction results and finite difference software FLAC 3D , the dynamic responses of the new blast-resistant structure and the traditional one were both calculated. Results showed that, after the deployment of wave converters, the peak absolute values of the bending moment, shear force, and axial force of the structure decreased generally, which verified the good blast-resistant effect of the new blast-resistant method.
