The helmet is a mandatory tool for safe production, and bamboo helmets can be used as an alternative to the traditional plastic safety helmet. In this study, bamboo helmets were modified with urea-formaldehyde resin and have shown excellent impact resistance, good color sensitivity, and high gloss. The excellent performance of the bamboo helmet comes from the structure designed by imitating the gradient characteristics of bamboo and the modification of urea-formaldehyde resin. The pores and defects of bamboo in the helmet modified by urea-formaldehyde resin are filled and repaired. The chemical combination of urea-formaldehyde resin and bamboo reduces bamboo&rsquo:s crystallinity and improves the bamboo helmet&rsquo:s impact resistance. The development of bamboo helmets provides a supplement and option for the traditional helmet market while opening up new ways of bamboo utilization.
