In this work, we study and characterize 20%- and 30%-reinforced rubber tire powder and polypropylene composite to apply it in the engine encapsulation of commercial vehicles. We produce a prototype with 20% of rubber tire powder due to its better processability and carry out external noise analysis and the results show it is similar to the already available material and within the limits established by law, besides presenting a substantial 54-weight% decrease. In addition, the material guarantees a minimization of sound pollution - through the attenuation of noise by the composite - and environmental, by the reduction of inappropriate disposal of waste tires.
在这项工作中，我们研究并表征了20%和30%增强的橡胶轮胎粉末与聚丙烯复合材料，以将其应用于商用车的发动机封装。由于其更好的加工性能，我们生产了一种含有20%橡胶轮胎粉末的原型，并进行了外部噪声分析，结果表明它与现有材料相似，且在法律规定的范围内，此外重量还大幅减少了54%。此外，该材料通过复合材料对噪声的衰减保证了声污染的最小化，并且通过减少废旧轮胎的不当处置实现了对环境的保护。
