In this paper, the effect of low temperature on the dynamic behavior of laminated composite plate subjected to impact load has been investigated experimentally and numerically. A special refrigerator device was designed and manufactured to achieve the required test temperature up to -30◦C. Four types of fiber reinforced/ risen plates (E-glass woven roving/UP, E-glass mat chopped/UP, carbon/UP and carbon/EP) are produced using the wet hand layup technique at 30% volume fraction. The tensile tests are done according to ASTM D3039. The plate was fixed from all sides and a steel ball of 23g mass is freely dropped from height of 0.5 m. The dynamic response of the plate was measured using vibration data collector (TVC 200). In numerical analysis the drop load impact behavior of composite plates was modeled using ANSYS finite element software. The results show that the laminated plates have the same dynamic behavior but differ in magnitude. The mechanical properties improved and the deflection decreased as the temperature decrease. The deflection decrease as the fibers layers number increase. The plate deflection of use E-glass fibers is greater than that of use the carbon fibers. The effect of temperature on composite plates use E-glass fiber reinforced is higher than that of using carbon. The effect of temperature on the composite plates use polyester resin is less than that of using epoxy resin. The experimental and numerical results showed a good agreement.

Keywords: Composite laminate plate, Low temperature, Impact load, Dynamic response
