Aluminum-plastic composite panel is a kind of new type energy-saving and environmental-friendly curtain wall decorative material, and is widely used in building exterior wall, curtain wall board, old building reconstruction and renovation and other projects. With the development and improvement of production and application technology, the performance and functions of aluminum-plastic composite panel products have been optimized continuously; especially at present, all countries in the world have more and more strict requirements on fire safety, and the fire safety standards of buildings also have been improved continuously. In this context, all the manufacturing enterprises have been actively developing new techniques to produce new type aluminum-plastic composite panels, and have significantly improved the fireproof and flame-retardant properties of the products on the basis of ensuring all the performance levels of the products being acceptable. This paper proposes optimal design suggestions via detection analysis on three groups of aluminum-plastic composite panel samples, and is of important practical significance to the research and development of the aluminum-plastic composite panel with low-combustion-heat and flame-retardant core material.

Curtain walls are the façade of choice in high-rise buildings and an indispensable element of architecture for a contemporary city. In conventional curtain walls, the glass panels are simply supported by the metal framing which transfers any imposed load to the building structure. The absence of composite action between glass and metal results in deep frames, protruding to the inside, occupying valuable space and causing visual disruption. In response to the limited performance of conventional systems, an innovative frame-integrated unitized curtain wall is proposed to reduce structural depth to one fifth (80%) allowing an inside flush finish and gaining nettable space. The novel curtain wall is achieved by bonding a pultruded glass fiber reinforced polymer (GFRP) frame to the glass producing a composite insulated glass unit (IGU). This paper selects the candidate frame and adhesive materials performing mechanical tests on GFRP pultrusions to characterize strength and elasticity and on GFRP-glass connections to identify failure module and strength. The material test results are used in a computer-based numerical model of a GFRP-glass composite unitized panel to predict the structural performance when subjected to realistic wind loads. The results confirm the reduction to one fifth is possible since the allowable deflections are within limits. It also indicates that the GFRP areas adjacent to the support might require reinforcing to reduce shear stresses.

In this study, bamboo charcoal (BC) was used as a substitute filler for bamboo powder (BP) in a lignocellulose-plastic composite made from polylactic acid (PLA), with aluminum hypophosphite (AHP) added as a fire retardant. A set of BC/PLA/AHP composites were successfully prepared and tested for flame-retardancy properties. Objectives were to (a) assess compatibility and dispersibility of BC and AHP fillers in PLA matrix, and (b) improve flame-retardant properties of PLA composite. BC reduced flexural properties while co-addition of AHP enhanced bonding between PLA and BC, improving strength and ductility properties. Adding AHP drastically reduced the heat release rate and total heat release of the composites by 72.2% compared with pure PLA. The formation of carbonized surface layers in the BC/PLA/AHP composites effectively improved the fire performance index (FPI) and reduced the fire growth index (FGI). Flame-retardant performance was significantly improved with limiting oxygen index (LOI) of BC/PLA/AHP composite increased to 31 vol%, providing a V-0 rating in UL-94 vertical flame test. Adding AHP promoted earlier initial thermal degradation of the surface of BC/PLA/AHP composites with a carbon residue rate up to 40.3%, providing a protective layer of char. Further raw material and char residue analysis are presented in Part II of this series.

Purpose – The purpose of this paper is to present a systematic approach for the evaluation and selection of curtain wall systems for medium-high rise building construction. Design/methodology/approach – The authors have identified the different types of curtain wall systems that are commonly used in the building construction industry in Saudi Arabia; examined the various performance as well as financial and non-financial criteria affecting the evaluation and selection of these systems; and subjected the identified different types of curtain wall systems to several filtering processes, namely feasibility ranking, evaluation by comparison and weighted evaluation to facilitate making a decision on the most suitable system to select. Findings – The analysis of the collected data indicated that the precast concrete curtain wall system is considered to be the first choice. The second choice is the prefabricated brick panel curtain wall system. Originality/value – Curtain walls are the most recognized elements of contemporary structures today. There exists ample variety of materials and designs that could be utilized for the development of these building elements. This paper is of practical value to project owners, architects and design professionals endeavoring on the process of selecting and specifying curtain wall systems in their projects.

The developing economy and convenience of traffic makes the building more and more large, and the traffic is also increasing quickly. The light pollution caused by glass curtain walls in high-rise building makes the traffic safety problems more and more serious. Enough attention should be paid towards it. A simulation software was written in order to make a graphic simulation of the sun's running status, analysis of various types of architectural glass curtain wall and building orientation on light pollution regional distribution effect. It's summed up that the use of decumbent form glass curtain wall can be effective in controlling light pollution area size and can reduce the glare range by properly reversing buildings, in order to avoid light pollution’s influence on traffic safety.

The feasibility of wood-plastic composite (WPC) and efficiency of impact strength improvement by toughening agents were discussed using waste polypropylene (PP) from e-wastes as experimental materials. The researching results indicated that it could be used in manufacturing wood-plastic composite while the impact strength of waste PP decreased by 47.3% comparing with new PP. Adding polyethylene octene elastomer (POE) and styrene-butadiene-styrene (SBS) could effectively enhance the impact strength of WPC. When adding 15% of POE and SBS individually, the impact strength increased by 113.2% and 43.4%. The modulus of rupture (MOR) and modulus of elasticity (MOE) lowered when toughening agents were added, which should be made into consideration in practical application according to the property of materials comprehensively.
