Properties of cryogenic and low temperature composite materials – A review

Fibre-based polymer composites are used in applications were there is the risk of an explosive blast. This paper presents a comprehensive review of published research into the blast performance of fibre-based composite materials, which includes fibre-reinforced polymer (FRP) laminates, fibre metal laminates, and sandwich composites with FRP facesheets. The dynamic loading experienced by composite materials under surface contact, near-field and far-field blast events is described. The various test methods used to experimentally evaluate the response of composites to shock wave and blast loading are reviewed. Experimental and modelling studies into the deformation and damage of composites caused by shock waves are also reviewed. The mechanisms by which fibre-polymer laminates, fibre metal laminates and sandwich composites absorb the shock wave energy generated by an explosive blast are analysed. The paper also reviews methods used to improve the blast performance of composites.

Advances in understanding the response of fibre-based polymer composites to shock waves and explosive blasts

A new method for fabricating glass fiber composite sandwich panel with pyramidal truss cores was developed based on the vacuum assisted resin transfer molding technology. The microstructure and organizations of fabricated sandwich panels were examined by the scanning electron microscope. The out-of-plane compressive tests of composite sandwich panels were performed throughout the temperature range from −60 °C to 125 °C. Then the effects of temperature on the compressive strength, compressive modulus and failure mechanism were investigated and analyzed. Our results indicated that cryogenic temperature resulted in the increasing of the compressive modulus and strength, while high temperature caused the degradation of the compressive modulus and strength. The effect of temperature on failure mode of composite sandwich panel was also observed. Analytical expressions were presented to predict the compressive modulus and strength of composite sandwich panels at different temperatures.
