PET 发泡材料被广泛应用于结构芯材、风电叶片、运动器材、船舶等领域。在2019年之前，低密度PET 泡沫芯材的复合结构材料的关键技术主要由国外企业垄断，严重制约我国相关产业的健康发展。不过，我国自主研发的新型发泡技术已经上市——“免干燥PET 反应挤出发泡一体化成型机组”的出现，不论是对丰富我国聚酯工业产品结构、扩宽PET 应用领域，还是促进我国高性能发泡材料制备技术及应用领域的开发，都具有十分重要的意义。本期会客室，北京化工大学教授、博导何亚东将详解这一技术的开发与应用。
如今，电动汽车（EV）市场正蓬勃发展。与汽车生产中使用的传统材料相比，复合材料有许多优点。它们可以很容易地加工成复杂的形状，并提供长期的性能和效率收益，同时复合材料技术的不断提升进一步拓宽了其应用范围。《汽车电气化推动复合材料创新》一文就阐述了电动汽车技术为复合材料的应用带来的新机遇。
近年来， 世界对可持续能源的开发越发重视。TreeComposites 是荷兰的一家复合接头设计和制造商，其开发了一种玻璃纤维增强塑料（GFRP）复材接头，用于连接WTG 基础结构中的钢管构件，取代了资源密集型焊接，显著降低了碳排放。
