Problems solved by technology

At present, the resin matrix of hollow composite materials mainly adopts thermosetting resins. However, thermosetting resins have the disadvantages of being non-recyclable, polluting the environment, and causing harm to workers’ bodies. Moreover, the preparation process of three-dimensional integral hollow composite materials is costly, long-term, and difficult to produce. Low efficiency, not conducive to industrial production
