1. A remoldable shape memory bismaleimide resin, wherein a preparation method of the remoldable shape memory bismaleimide resin comprises the following steps:
(1) in the presence of a quaternary ammonium salt, reacting a 2-allylphenyl glycidyl ether with adipic acid to prepare bis(3-(2-allylphenoxy)-2-hydroxypropyl)adipate;
(2) mixing bis(3-(2-allylphenoxy)-2-hydroxypropyl)adipate, bismaleimide, and a zinc compound to obtain a remoldable shape memory bismaleimide resin system;
(3) curing and post-treating the remoldable shape memory bismaleimide resin system to prepare the remoldable shape memory bismaleimide resin.
