A key component in a country's plan to build a national rail network is high-speed trains. A key aspect in the design of high-speed trains is the structural feasibility of the train. Issues that may interfere with the operation of the train need to be anticipated and assessed as this can result in huge losses. The mascara section at the front of the train must be well designed to protect the driver from unexpected external disturbances. Therefore, the selection of materials to be used by the train is very important because the selection of materials will affect the crashworthiness of the train, especially at the front of the train, the mascara, which will protect the driver from unexpected external disturbances. Therefore, this study will investigate how the material type and skin type of the mascara affect the crashworthiness response of a high-speed train. The material to be evaluated is composite. This document reports on the evaluation of the response of a composite panel representing a mascara when hit by a foreign object such as a stone or a bird at high speed. The research began with a literature study on the impact aspects of birds on railroad, ABAQUS software, and composite materials. Next, composite specimens were made and tested for mechanical properties and to determine their resistance to high-speed impact and an external object modeled as a projectile. Simulations are then conducted to analyze the results and compare them with the experimental results. The damage and failure of the composite plate will be analyzed between the experimental and simulation results, as well as identifying the ballistic limit of the composite plate itself, so that for future research, composite materials can be further studied to improve the quality and crashworthiness of high-speed trains. From the experimental and simulation results, it can be said that the composite plates suffer the same damage of delamination and fiber damage, and when the material parameters are modified by multiplying the value by four, the composite plates are able to withstand the impact force when traveling at high speed.
