聚乳酸（PLA）低聚物作为偶联剂在磷酸盐基玻璃纤维/PLA复合材料中显示出更高的界面剪切强度。为了影响玻璃纤维表面的粘结，使用具有不同端基的短链PLA低聚物作为偶联剂。通过缩合反应制备了具有钠盐端基、羧酸端基以及1、2和5个羟基的低分子量聚乳酸，并将其施涂到纤维表面。发现施胶纤维/聚乳酸复合材料的力学性能提高。XPS和TG分析表明，偶联剂在纤维表面的存在。SEM分析进一步证实了偶联剂的存在。(C)2010爱思唯尔有限公司版权所有
Polylactic acid (PLA) oligomers as coupling agents have shown higher interfacial shear strength in phosphate based glass fibres/PLA composites To influence bonding on the glass fibre surface, short chain PLA oligomers with different end groups were used as coupling agents. The low molecular weight PLA with a sodium salt terminal group, a carboxylic acid end group and also with one, two and five hydroxyl groups were produced and applied on the fibre surface through a condensation reaction Mechanical properties of the sized fibres/PLA composites were found to be increased XPS and TG analyses showed the presence of the coupling agents on the fibres surface SEM analysis further confirms the presence of the agents.
