在台灣,摩托車是大多數人的交通工具,性能好,機動性高,但遭遇事故時,受傷的往往是摩托車之騎士,因此需要有效且安全的防護措施,所以政府規定騎乘機車須配戴安全帽,安全帽可以在你受到撞擊時,即時保護頭部。安全帽樣式非常多種,可以完整保護頭部的是全罩式安全帽,目前市面上所受的全罩式安全帽之重量對頸部而言是有負擔的,本研究目的在於探討安全帽內部聚苯乙烯受撞擊過後情況,在與碳纖維複合材結合,希望運用碳纖維高強度、質量輕的特性,可以大幅使安全帽的重量減輕,同時也可達到保護頭部的功能。
聚苯乙烯為多孔性材質,本研究除了試驗安全帽用之聚苯乙烯之外,也另外比較市面上另外兩種密度不同的聚苯乙烯,探討孔隙度對應力應變曲線的引響。本實驗使用Al7075之霍普金森桿進行衝擊試驗,除了單純聚苯乙烯之外,也搭配碳纖維的黏貼,探討撞擊後黏貼碳纖維的聚苯乙烯受力情況。

In Taiwan, the motorcycle is most people's transportation, good performance, high mobility. When an accident, the injured is often the rider of the motorcycle. Therefore, we need protective measures to protect our life. The government stipulate a law. Riding motorcycles must wear helmet. Because an accident happened, it will be protect your head immediately. Helmet have many type. Protect your head of helmet type only Aurvana helmet. But this type is too heavy for the neck, the purpose of this study is to discuss a safety helmet’s polystyrene by the situation after the collision, combine with carbon fiber composite, hope to use the characteristics of carbon fiber, high strength, light quality, reduce the weight of helmet.
Polystyrene is porous material, this study investigate the polystyrene of helmet, and two kinds of different density polystyrene. Discussing the porosity effects of stress and strain. The experiment using splite hopkinson pressure bar, investigate the adhesive carbon fiber and no adhesive carbon fiber of polystyrene after impact.
