Properties of composite materials for cryogenic applications

The effect of low temperatures on the intermediate and high velocity impact response of CFRPs

“…Korab et al [10] and Rogers et al [11] carried out tests to obtain thermal expansion coefficients for cross-ply, woven, and unidirectional laminates. Giesy [12] described the variation of the laminate strength with temperatures from 2 269 to 23 8C and found a slight increase in tension and a small decrease in compression at low temperature as compared with those at room temperature, while Schutz [13] observed an increase in both tensile and compressive strengths. Morino et al [14] and Aoki et al [15] analyzed the interlaminar fracture process and showed that matrix cracking is the main problem when CFRPs are considered for cryogenic applications.…”

Static behavior of CFRPs at low temperatures

“…These conditions affect the mechanical properties of the material by two reasons [3,4]: (a) the variation of the properties of the constituents of the material and (b) the appearance of residual stresses inside the material due to the mismatch between the thermal expansion coefficients of fibers and of the matrix. It is necessary, therefore, to carry out a mechanical characterization over the complete range of temperatures that can be reached during the operational life of components made of these materials [5].…”

“…Baschek and Hartwing [17] computed the thermal stresses in an industrial piece manufactured with graphite fiber cross ply laminates subjected to thermal loading at temperatures ranging from 50 up to 179 8C, taking into account the temperature dependence on the thermal expansion coefficients of the materials. Schutz [3] summarized the quasi static properties of different polymer matrix composite materials at tem peratures ranging from 20 to 269 8C. In CFRP uni directional laminates, the Young modulus and the ultimate tensile stress increase as the temperature decreases.…”

Design and Manufacture of a Fiber Pyro Expanded Perlite/Epoxy Composite for Thermal Insulation

“…The class of epoxy resin utilized to make the composite material is used as the matrix. The reinforcement uses fibers such as boron, alumina, aramid, S-glass, E-glass and carbon in applications relate to cryogenic engineering fields [1].…”
