## 1 Introduction  
The combination of ductile materials and brittle materials can result in a lightweight material, which prevents penetration and effectively protects the human body [1, 2]. Fiber-reinforced composite laminate is suitable for protection against higher-tethality fragmentation threats [3]. Therefore, fiber-reinforced laminate behind ceramic could perform significantly as a ductile material in protecting a human torso [4, 5, 6]. In addition, fiber-reinforced laminate could also be made into a protective helmet as a weight-critical application [3]. Ultra-high-molecular-weight polyethylene (UHMWPE) fiber has exceptional physical and mechanical properties, such as high impact resistance, high wear resistance, high chemical resistance, and low friction coefficient [7]. Therefore, it is widely used in ballistic protection, as well as the aerospace and military industries [8, 9]. In typical UHMWPE ballistic composite sheets, unidirectional (UD) layers of fibers are impregnated with a thermoplastic matrix, and they are stacked in 0\({}^{\circ}\)/90\({}^{\circ}\) arrangement [10]. For flexible applications like ballistic vests, UD layers are covered on both sides with a thin polymer film [10] and stacked to become a laminate as shown in Figure 1. This structure gives far better protection than fabrics with the same weight [11]. There were many experiments and numerical simulations studying the impact response of UHMWPE laminate [12; 13; 14; 15]; however, the mechanics of resisting impact threats remains poorly understood [16]. To achieve the necessary understanding of the mechanics of resisting impact, it is essential to study the dynamic compressive properties of UHMWPE fiber-reinforced laminate. Moreover, the methods applied in testing other fiber-reinforced composites are necessary as important references. For other fiber composites, [PERSON] [17] studied the compressive material properties and damage kinetics of cubic specimens of [0\({}^{\circ}\)/90\({}^{\circ}\)]\({}_{26}\) (26 repetitions of [0\({}^{\circ}\)/90\({}^{\circ}\)] stack) woven E-glass/vinyl ester laminate in the in-plane and out-of-plane directions from low to high strain rates. The results showed that a higher strain rate led to a higher maximal stress level. In addition, the maximal stresses obtained during dynamic compression tests were higher for the composite subjected to in-plane loading than for that subjected to out-of-plane loading at the same strain rate. Moreover, the specimens were mainly damaged in a crushing and shear failure mode under out-of-plane loading; as for the in-plane test, the failure was dominated by fiber buckling and delamination. [PERSON] [18] evaluated the rate dependence of the through-the-thickness and in-plane compression response of a three-dimensional (3D) 6% Z-fiber woven composite (3 DWC). It was found that 3 DWC showed an increase in strength in all three directions studied. In the warp and weft directions, the material had a clear transition in the failure mode dominated by kink band formation at low rates to delamination at much higher rates. For UHMWPE woven composites, [PERSON] [19] studied the compressive stress-strain curve, strain at yield stress, and impact energy absorption of UHMWPE/vinyl ester 2.5D angle interlocked woven composites under three high strain rates (360, 710, and 1120 s\({}^{-1}\)) and quasi-static compression. The results showed that the yield stress, strain at yield stress, and modulus all increased with the increased strain rate. [PERSON] [20] studied the dynamic compressive properties of UHMWPE interlaced biaxial weft knitted (IBWK) fabrics/vinyl ester resin composites. The results showed that the peak stress, compressive modulus, and specific fracture strain energy density increased with the increase in strain rate.
