Definition Of

The need to reduce the overall weight of aeronautical and space structures while preserving or even improving their performances make the research and development in the field of advanced composite materials necessary for the advancement of aerospace technologies. This paper provides an overview of composite materials and their fiber reinforcement technology in aerospace field. We discuss the reasons for aircraft manufacturers and airlines to use composites and illustrate the definition of composite material. Then, we list the advantages and disadvantage of composite materials and cite different fiber reinforcement technologies of carbon fibers, aramid fiber, UHMWPE, etc. At last, we summarize the present and future applications of composites materials in aerospace and other civil fields.

The strikes of the meteoroids represent a serious danger for transformable space structures. Multilayer plates and shells made of hybrid composite materials can be effectively used for protection and thermal control of such structures. The results of the analysis of the thermal regime and shock resistance of a multilayer structure flying in a circular orbit 400 km high are presented.

Advanced Composite Materials

Advanced composite materials are playing an increasingly important role in the design and fabrication of high performance space structures. Composite materials may be tailored for a particular application to establish a unique combination of high specific stiffness and strength, dimensional stability and specific damping which makes these materials ideal candidates for many applications in the hostile space environment. Demonstrative examples of typical applications to primary structures and payloads, each with a different set of performance requirements, are presented in this paper. Unfortunately, the use of polymer matrix composites for very long exposure to space has not been without problems due to various environmental effects which are discussed. The use of metal matrix composites is proposed as a possible solution to the problem. However, an understanding of the fundamental properties of composites and their response to space environmental effects is essential before the full benefit of these materials can be realized.

Nowadays scientific researchers aim to develop new material designs for space structures that can withstand the harsh conditions in space environment. Another goal is to reduce the weight and the launching cost of the structures. A solution to those needs is to integrate fiber reinforced polymers in spacecraft structural components. Radiation shielding is a requirement that has to be met by the materials used to manufacture space structures. Protons are one of the many charged particles that can influence the integrity of materials in space. In the present study three material designs were developed and their ability to shield proton beam irradiation was evaluated. The material designs consist in advanced composite materials (carbon fiber reinforced polymers - CFRPs) that integrate the concept Low Z - High Z - Low Z (tantalum foil) and metallic coatings. Simulations were performed to determine the penetration depth of an ion beam (energy 15 MeV) in the proposed material designs. It was observed that the beam�s penetration depth through a CFRP sample with Ta foil (sample�s thickness 2.08 mm) was about 75% of the sample�s thickness, 58% for CFRP sample with Babbitt coating (sample�s thickness 2.28 mm), 56% for the CFRP sample with Zn coating (sample�s thickness 2.28 mm) and 55% for the CFRP sample with Zn/Monel coating (sample�s thickness 2.28 mm). It seems that the proposed material designs provide ion beam protection similar with an aluminum sample of 2 mm thickness. The experimental procedure confirmed the results obtained from the simulations, all the material designs providing protection in case of proton beam irradiation with an energy of 15.8 MeV.

Modern polymer composite materials with high specific characteristics of strength and stiffness allow creating strong, durable and geometrically stable space structures. To expand the scope of application of composite materials and increase the competitiveness of space structures, it is necessary to further improve design methods with the widespread use of multiscale computational modeling of deformation and fracture processes. The paper presents the results of analysis on the strength and dimensional stability of structures made of polymer composites. A metal-composite high-pressure tank for electric propulsion systems and the design of precision reflectors for space- and ground-based antennas are considered. The methods and results of experimental and computational studies on the stress-strain and ultimate states of structures are described. The methods and means of non-destructive testing, the results of the analysis on the stress-strain state and full-scale tests of the tank structure are described. Generalized estimates of the load-carrying capacity of reflector structures under given operating conditions are given.

The paper considers the problem of sensitivity of large precision space structures made of high-modulus fibrous polymer composite materials to external and internal microdynamic effects. This problem is related to the extent of structure forming elements, as well as to an abrupt increase in the elastic modulus of the material when passing the threshold of low stresses. It is found that under low loading in the orbital flight conditions the calculated values of the elastic modulus of large precision space structures made of high-modulus fibrous polymer composite materials may be higher than the real ones by more than 20 times, which must be taken into account in the calculations. Possible ways to reduce the sensitivity of such space structures made of high-modulus fibrous polymer composite materials to external and internal microdynamic effects are shown.
