Correlating phenolic resin chemical structure with thermo-mechanical properties

该项目将与DSTL资助的其他预测酚醛树脂和酚醛树脂基复合材料吸湿影响的工作同时进行。这项工作的一个问题是缺乏从基本和系统的角度对酚醛树脂性质的理解。一系列酚醛树脂将由不同的苯酚与甲醛的比例导致样品具有不同的性能。然后将对这些树脂进行测试，以了解基本化学结构与最终树脂性能之间的联系。接下来将制备特定品种的复合样品，以观察纤维如何影响酚醛树脂的化学性质。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.
