碳纖維和玻璃纖維組合增強塑料組分

含量和孔隙含量的測定

1范圍

本文件規(guī)定了測定碳纖維和玻璃纖維組合增強塑料中碳纖維含量、玻璃纖維含量、樹脂含量和孔隙

含量的原理、試樣、試驗儀器與試劑、試驗步驟、結果計算及試驗報告等。

本文件適用于濃硫酸在一定條件下能使樹脂基體完全消化且對纖維僅產生輕微腐蝕的碳纖維和玻璃

纖維組合增強塑料。

2規(guī)范性引用文件

下列文件中的內容通過文中的規(guī)范性引用而構成本文件必不可少的條款。其中，注日期的引用文

件，僅該日期對應的版本適用于本文件；不注日期的引用文件，其最新版本（包括所有的修改單）適用

于本文件。

GB/T1033.1塑料非泡沫塑料密度的測定第1部分：浸漬法、液體比重瓶法和滴定法

GB/T30019碳纖維密度的測定

GB/T40724碳纖維及其復合材料術語

GB/T41063玻璃纖維密度的測定

3術語和定義

GB/T40724界定的術語和定義適用于本文件。

4原理

已知質量的試樣，基體部分被熱硫酸介質消化，熱硫酸消化基體后，含有增強材料的殘余物經過

濾、清洗、干燥、冷卻和稱量，再在一定溫度下灼燒、冷卻、再稱量。試樣消化損失部分為基體樹脂，

灼燒損失部分為碳纖維，灼燒后剩余部分為玻璃纖維，由此可計算出纖維增強塑料中各組分質量含量。

根據(jù)纖維增強塑料、碳纖維、玻璃纖維和樹脂澆鑄體的密度，分別計算出纖維增強塑料中各組分的體積

含量及孔隙含量。
