Introduction

As a number of space debris and space structures in low earth orbit (LEO) increases, risk of collision has also increased [1][2]. Space debris is usually flying LEO at a speed of 8 - 9 km/s. With its immense kinetic energy, collision is more likely to leave fatal damage onto a space structure [3][4][5]. For reducing such damage, thin metal Whipple Bumper is installed as outer shields off of foundation wall. Whipple shields prevent direct hit to foundation wall as well as reducing damage by letting debris in fragments; thus, diffusing debris kinetic energy. [6][7][8]. Shimizu et al. studied PEEK resin the matrix CFRPs mechanical properties against low speed impact under low (243 K) to high (453 K) temperature environment [9]. On this research, influence of impact velocity and temperature on CFRP is studied by creating high speed collision under cryogenic temperature. In addition, the research focused on laminated constitution to understand CFRPs mechanical property. Specimens composed of two carbon fiber plates are arranged to have two different laminated constitutions.
