A preparation method of vinyl ester resin for optimizing heat-release during curing includes: (A) providing a vinyl ester, a solvent and a phase change material to perform mixture; (B) performing a heating process to remove the solvent, so as to obtain a vinyl ester resin containing the phase change material. Thereby, the organic PCM material with high heat absorption and good resin affinity can be used as the temperature control agent of the vinyl ester resin during the curing process for avoiding the defects such as bubbles and cracks being generated in the vinyl ester resin.

An improved vibration suppressed bicycle structure includes a frame and a handle set that have ceramic piezoelectric elements located thereon to couple with passive and active control energy consuming mechanisms to convert the vibration energy of the bicycle body into electric energy, which is consumed in heat or gathered for active control use. The invention can absorb vibration energy of the bicycle to enhance structural performance, reduce vibration, and give bicycle riders more comfort over long distance rides and improved maneuverability.
