MOF-derived strategy to obtain CuCoOx functionalized HO-BN: A novel design to enhance the toughness, fire safety and heat resistance of bismaleimide resin

Fire in buildings is one of the major threats. This threat is increasing day by day. This problem necessitates the building designers, construction professionals and the fire professional to find the solution. A detailed study with analysis requires towards the existing fire safety measures. This study analysis results will reveals the adequacy of existing measures. In this article one of the multifunctional building is selected as research sample. In this building applied research type is adopted. Case study method is used to study the each component of the building. The planning parameters of the building and the designing of the structural position are observed in depth manner. The non-combustible materials are identified in the construction of the building. The heat resistance adequacy of each components of the building is evaluated with respect to codel recommendations. The basic concept of fire and life safety measures in buildings are common in international, national and the regional level. These recommendations are thoroughly applied in this research work. These works are analyses and the results or findings are derived. These results are summed up and explained about its objectives. The paper is concluded with comprehensive fire safety measures applications in buildings and recommends fire related various factors research in future. The ultimate aim of this article work is to safe guard lives and property in buildings.

Bismaleimide Resins

Novel carborane-containing bismaleimides with excellent heat resistance and dimensional stability for advanced composites are presented. First, a new kind of carborane-containing mono-maleimido-terminated monomer 1-(4-tolyl)-2-(4-maleimido phenyl)- o-carborane (CB-MI) was synthesized and characterized by FT-IR and 1H-NMR. Then, it was used as a modifier for bismaleimide resin 4,4’-bismaleimidodiphenylmethane (BDM) with different weight fraction of CB-MI. The curing behavior and thermal property of the CB-MI/BDM resin systems were studied and presented here. Results displayed that a wide processing window and low curing temperature provided a good processability for the CB-MI/BDM resin system. Due to the effect of carborane groups, the char yield at 600°C of the cured resin systems tended to be increased with the addition of CB-MI. Moreover, the coefficient of thermal expansion of the resin was found to be reduced with the increase of CB-MI, indicative of a remarkable dimensional stability. This study might open up great opportunities for the preparation and design of various novel bismaleimides in a simple and feasible way and the resins with good thermal property and processability at the same time.
