Fire resistance certification of aircraft composite materials

Fibres composite materials designed as glass fibre, carbon fibre and aramid fibre. They were used for chemical resistance, compressive strength, stiffness, impact resistance, and fire resistance. However, they had a number of limitations, including vandalism, accidental damage, short-term durability, high cost, and suitably qualified staff shortage. These problems could be solved by appropriate monitoring, suitably qualified designers and contractors. The design and use of fibre composite materials has become an important aspect of engineering.

This paper demonstrates how advanced composite materials as F.R.C.M. (fiber reinforced cementicius matrix) can offer high advantages for repairing ageing infrastructures. The FRCM strengthening system can be considered alternative to the well-known fibre-reinforced polymers (FRP) system. The FRCM system, in fact, permits the elimination of some disadvantages related to the use of organic resin, such as lack of fire resistance and low compatibility with the concrete substrate. In this study, a data comparison between non-reinforced and reinforced models is discussed. The specimens simulated a part of a bridge deck to repair or strengthen. The samples were no. 6 plates 70x70 cm ² long and 10 cm thick realized by a mix design concrete [1] of 30/35 class and reinforced by steel bars. The strengthening system consists in applying the composite biaxial sheet at the intrados of the deck in two layers orthogonal to each other.

Fiber reinforced polymer (FRP) are rapidly gaining popularity in various fields of civil engineering. For decades, these materials have been used to strengthen structures that are not exposed to fire, such as bridges. To apply this reinforcement method to increase the bearing capacity of structures of buildings and structures, fire resistance is an important feature for any material. Due to the small amount of research in this area, there is no technical documentation for these structures that regulates the coupling properties and mechanical characteristics at elevated temperatures necessary for design. There is also a need to develop a simple method for calculating the fire resistance and thickness of an insulating material for a reinforced structure. This article combines existing studies of the operation of fibers and a binder reinforcement system at high temperatures. The article also presents experimental results and numerical studies at elevated temperatures of various authors for isolated and non-insulated reinforced concrete structures reinforced with polymer composite materials. In addition, a comparison of the fire resistance of two main methods of reinforcing polymer composite materials is given: an externally bonded reinforcement and a near surface mounted method. Strengthening structures by near surface mounted method has great advantages compared to strengthening by externally bonded reinforcement.

Intermetallic Composite

Transmission electron microscopy of metallic/intermetallic composite materials is most challenging since the microscopist typically has great difficulty preparing specimens with uniform electron thin areas in adjacent phases. The application of ion milling for thinning foils from such materials has been quite effective. Although composite specimens prepared by ion milling have yielded much microstructural information, this technique has some inherent drawbacks such as the possible generation of ion damage near sample surfaces.

Definition Of

Although most materials contain more than one phase, and thus are multiphase materials, the definition of composite materials is commonly used to describe those materials containing more than one phase deliberately added to obtain certain desired physical properties. Composite materials are often classified according to their application, i.e. structural composites and electronic composites, but may also be classified according to the type of compounds making up the composite, i.e. metal/ceramic, ceramic/ceramie and metal/semiconductor composites. For structural composites it is also common to refer to the type of structural reinforcement; whisker-reinforced, fiber-reinforced, or particulate reinforced composites [1-4].For all types of composite materials, it is of fundamental importance to understand the relationship between the microstructure and the observed physical properties, and it is therefore vital to properly characterize the microstructure. The interfaces separating the different phases comprising the composite are of particular interest to understand. In structural composites the interface is often the weakest part, where fracture will nucleate, and in electronic composites structural defects at or near the interface will affect the critical electronic properties.
