The Impact

This research discusses about comparison, testing, and analyzing composite materials for develop the building panels for lightweigh-wall applications made from wood-industrial waste materials. Wood sawdust is used as a composite cement mixture as a binder of all materials with the mixture 0%, 5%, 10%, 15%, and 20% of total weight. This research uses quantitative methods with blocks as a sample sizes 10cm x 3cm x 1cm. The test includes flexible test, porosity test, and composite walldensity test to find out mechanical and physical properties of composite material. The result of this research shows that the usage of wood sawdust as a mixture for making composite panel with 0.4 water-factor at 28 days-age get the optimum value at 15% of mixture variation with flexibility of 7.18 MPa, density 1.61 kg/m³ and compressive strength of 58.42, MPa. These results indicate that the wall panel meets the requirement of SNI 03-0349-1989 with concrete steel-brick level IV as a non-structural brick. Based on these results, it can be concluded that composite panel can be used on the wall as an effort to reduce the impact of the ruins of the building, and reduce the danger as a disaster mitigation effort.

Operational Factors

One of the principal criteria of aircraft composite design strength on the conditions of damage tolerance is the minimum defect size of accidental impact damage that is sure to be located during regular maintenance checks. Construction strength with similar (BVID – Barely Visible Impact Damage) and smaller damages must be ensured under design load. The analysis of operational factors affecting the criterion value is conducted in the paper. The effects of personnel qualification, surface color, level of contamination, distance to the object as well as defect size variations during the time due to relaxation of inner strains in the damaged construction were studied.Research was carried out using 90 carbon fiber three stinger panels of different color and contamination levels which were subject to impact damages by a 25 mm spherical striker. Totally 80 blows were struck when applying energy within the range of 3–107 J. In the visual damage detectability test under different conditions 42 experts were participated including 25 airlines inspectors. For the statistical analysis of empirical data and determination of dependence for the damage detection probability on its size, the Weibull function was utilized. Determination of BVID size using "90/95" criterion was performed by means of the bootstrap method (95% of inspectors must detect not less than 90% of defects with the size not smaller than BVID). The results obtained in this study enabled to access the degree of various operational factors impact on reliability of damage detectability during the visual inspection and determine BVID values depending on the combination of the given factors. In particular, it was demonstrated that from all the viewing distances the defects in polymer composite materials are more detectable on the blue surface than on the gray and red ones. Conducted research demonstrated a significant effect of relaxation (the reduction effect of the surface defect sizes in the composite panel affected by different factors during time span) on the probability of defect detectability during operation. Also water saturation of the construction under excessive temperatures has the critical compared with other factors impact on relaxation of damages in polymer composite materials. The obtained results accord with the data in foreign publications making them more supplement and specific. On the basis of conducted research the entire range of recommendations for aircraft designers and operators utilizing composite constructions is formulated.

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.

Epoxidized Linseed Oil

Flammability of polymer composite appears to be one of the greatest threats and hence limits its advanced applications. Polymer composite materials can be designed to obtain wide ranges of properties in comparison with traditional materials. However, almost common polymers include the intrinsic flammability, restricting their applications in spite of their flexibility and performance efficiency. In this study, a material based on epoxy Epikote 240 resin 90 phr and epoxidized linseed oil 10 phr was prepared. In order to improve the material's flame retardancy ability but maintain its mechanical strength, the mixture of flame retardants including 9 phr antimony trioxide and 11 phr chlorinated paraffins along with amin compounds as a curing agent were added into the material. In addition, E-glass woven fabric (E 600g/m2 ) was used to improve mechanical strength of the material. As a result, the material was considered as the flame- retardant material with LOI index to be 30.3%.
