200933118 九、發明說明: t發明所Λ之技術領域3 本發明係關於一種包含纖維層之非固結堆疊體及一層 或多層創傷減少層之多層材料片。 5 【先前技術】 此種多層材料片係用於軟性防彈物件,諸如防彈背心 及軟性盔曱系統。此種物件之一項重要要求顯然係可停止 衝擊該物件之子彈。但此外,也重要地須限制物件的變形, 特別為創傷或背面變形(B F D ),例如軟性盔甲系統可停止衝 1〇擊的子彈免於穿透該系統,但可能於其非衝擊侧上變形太 嚴重因而對欲藉該盔曱系統保護之設備及人受損。技藝界 已經提示於軟性防彈物件限制BFD之解決之道。此等解決 之道通常提示係添加創傷減少層至該多層材料片之背面, 亦即與面對彈道威脅側(亦即撞擊側)相對之表面。 15 包含一纖維層堆疊體及數層創傷減少層之多層材料片 由US 2003/0200861A1為已知。本公開文獻揭示包含至少兩 小堆之-總成之身體蓋甲系統,各小堆含有多層纖維層。 根據US 2003/0200861A卜第-小堆包含多層纖維層,其係 配置來於第一小堆之前接收來自於子彈的衝擊,允許子彈 減1·曼速度。於第一小堆之纖維層可配置成針刺鼓形式。第 =堆耗散該衝擊之輪入能,對抗第二小堆被子彈所完全 透。於第二小堆之纖維層可呈防彈纖維之編織物形式。 二所揭下之多層㈣#之小堆經常係額成第—小堆係位 “隹疊體外側。因此’根據US 2G03/0200861A1之教示, 200933118 用來減慢子彈速度之纖維層須位於多層材料片之背面。經 由減慢衝擊時的子彈速度,顯然可減少創傷。 雖然根據US 2003/0200861A1之多層材料片顯示滿意 的防彈效能,但此種效能仍可更進一步改良。 5 【發明内容】 本發明之目的係提供一種比較已知材料具有於減少創 傷或背面變形之改良防彈性質之多層材料片。 根據本發明之目的可經由提供一種包含一纖維層堆疊 體以及一個或多個創傷減少層小堆之軟性防彈物件而達 10成,其中該等小堆中之至少一者係位於該堆疊體内部。出 乎意外地發現此種特徵之特定組合比較已知之多層材料 片’可獲得呈減少創傷或背面變形形式之改良防彈效能。 更特定言之’多層材料片之平均BFD出乎意外地小於聚類 似重量之已知多層材料片之BFD。此點特別可用於需要質 15輕之用途’諸如防彈背心。低重量對防彈背心的穿戴者提 供最大舒適。因根據本發明之材料片比較已知材料片提供 改良之安全邊際,因此可由較少纖維層所組成因而質量較 輕0
