Two types of polymer waste materials, poly(ethylene terephthalate) (PET) and polycarbonate based Colombian Resin (CR-39), were used for the designing of fully recycled composite materials. Waste PET was employed for the synthesis of thermoset unsaturated polyester resin (UPR), while CR-39 was used as reinforcement in the UPR matrix. Prior to mixing, CR-39 particles were subjected to oxidation and chemical activation using acids/base and ethanol amine, respectively. The effect of the modifier type and variable loading of the activated CR-39 particles on mechanical and dynamic-mechanical properties of the corresponding composites was investigated. The greatest improvement in the tensile and flexural strength of UPR resin was achieved with the composite containing 0.5 wt% of amine activated filler particles, 96.0% and 62.2%, respectively. The Arrhenius equation was used to calculate the activation energy for glass transition from dynamic mechanical properties measured at various frequencies. The activation energy of the main transition for UPR resin and composites were calculated to be 173 and 350 kJ·mol⁻¹ indicating that reinforcement results in an increase in the energy barrier to macromolecules viscoelastic relaxation. In addition, erosion resistance was studied during exposure of samples to cavitation tests. According to the obtained results, these materials can be applied in construction and mining industry.

两种类型的聚合物废料，聚对苯二甲酸乙二醇酯 (PET) 和聚碳酸酯基哥伦比亚树脂 (CR-39)，用于设计完全回收的复合材料。废 PET 用于合成热固性不饱和聚酯树脂 (UPR)，而 CR-39 则用作 UPR 基体中的增强材料。在混合之前，分别使用酸/碱和乙醇胺对 CR-39 颗粒进行氧化和化学活化。研究了改性剂类型和活化 CR-39 颗粒的可变负载对相应复合材料的机械和动态机械性能的影响。UPR 树脂的拉伸和弯曲强度的最大改进是在复合材料中分别含有 0.5%（重量）、96.0% 和 62.2% 的胺活化填料颗粒。Arrhenius 方程用于根据在不同频率下测量的动态机械性能计算玻璃化转变的活化能。UPR树脂和复合材料的主跃迁活化能为173和350 kJ·mol^-1表明增强导致大分子粘弹性松弛的能垒增加。此外，在样品暴露于空化试验期间研究了抗侵蚀性。根据所得结果，这些材料可用于建筑和采矿业。
