Correlating phenolic resin chemical structure with thermo-mechanical properties

该项目将与DSTL资助的其他工作并行进行，以预测酚醛树脂和酚醛树脂基复合材料中吸湿性的影响。这项工作的问题之一是从基础和系统的角度缺乏对酚醛树脂性能的了解。一系列酚醛树脂将以不同的苯酚和甲醛比例制成，从而产生具有不同性质的样品。然后将对这些进行测试，以了解基本化学结构和最终树脂性能之间的联系。随后将制备特定品种的复合样品，以了解纤维对酚醛树脂化学的影响。该项目还将使用获得的数据作为聚合物和聚合物复合材料性能的混合模型的输入和验证。

This project will run in parallel with other DSTL funded work predicting the impact of moisture absorption in phenolic resins and phenolic resin based composites. One of the issues with this work is a lack of understanding of phenolic resin properties from a fundamental and systematic point of view. A series of phenolic resins will be made with varying phenol to formaldehyde ratios resulting in samples with varying properties. These will then be tested to understand the link between the basic chemical structure and the properties of the final resin. This will be followed by preparing composite samples of a specific variety to see how the fibres affect the phenolic resin chemistry. The project will also involve using the data obtained as input to and validation for a hybrid model for both polymer and polymer composite properties.
