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.

该项目将与其他DSTL资助的预测酚醛树脂和酚醛树脂基复合材料吸湿影响的工作并行运行。这项工作的问题之一是缺乏从基本和系统的角度对酚醛树脂性能的理解。一系列的酚醛树脂将与不同的苯酚甲醛比例，导致样品具有不同的性能。然后将对这些进行测试，以了解基本化学结构与最终树脂性能之间的联系。随后将制备特定种类的复合材料样品，以观察纤维如何影响酚醛树脂的化学性质。该项目还将涉及使用所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。
