Fiberglass-reinforced necks for liquid nitrogen vessels
This article examines the effect of the chemical composition of glass fibers on the physicomechanical properties of the fiberglass-reinforced plastics based on these fibers at temperatures of 293 and 77/sup 0/K. The strength of the fiberglass-reinforced plastic in tensile loading is determined mainly by the strength of the glass fibers. The results indicate that the strength of the fiberglass reinforced plastic based on the fibers of nonalkaline composition at 77/sup 0/K and the strength of the fiberglass-reinforced plastic based on fibers of high-modulus glass at 293/sup 0/K are almost identical and equal. The increase of the strength of the fiberglass-reinforced plastic in bending with the reduction of temperature from 293 to 77/sup 0/K for all the fiberglass-reinforced plastics examined equals on average 88%. It is concluded that the fibers based on the alumoborosilicate nonalkaline glass are most suitable for the manufacture of the fiberglass-reinforced plastics working at cryogenic temperatures.
