Char derived from pyrolysis of plastic wastes represents about 20 wt.% of the released pyrolysis products. In order to maximize the economic benefits and applications of this fraction, this research aims to refine and reprocess char derived from plastic waste into carbon particles, then using it as a micro-filler material for light material applications. The experiments were performed on char derived from pyrolysis of metallised food packaging plastics wastes (MFPWs) that represent the most complicated part in plastic waste, and their char is usually loaded with aluminium elements. The experiments started with treating MFPWs in pyrolysis plant with a capacity of 250 g, followed by separation of char from other pyrolysis products. The derived char was exposed to a milling process followed by a leaching process to separate Al fraction and other heavy metals. The liberated carbon particles were exposed to functionalization process to remove any contamination and amorphous impurities. The functionalized carbon black particles in the form of spherical microparticles (FBC: 0.25, 0.5, 0.75, and 1 wt.%) were used to enhance the mechanical impact, and thermal behaviour of fiberglass/epoxy composite laminates. The composite panels were prepared using vacuum-assisted resin transfer and curing processes. The morphology and the composition of FBC were examined using SEM-EDS and FTIR. Also, SEM and Optical Microscope were used to observe dispersion of FBC, microstructure, impact mechanism, and surface morphology of the fabricated matrix. The mechanical and impact properties of the panels were tested according to ASTM-D7025 and ISO 6603-2 standards, respectively. Finally, thermal behaviour of the panels was studied using a thermogravimetric analysis. The results showed that 0.75 wt.% of FBC were enough to improve the modulus of elasticity of panels by ∼22%, compared to a pure sample. In addition, thermal stability and energy impact absorption at the same concentration of FBCs were improved by 21% (in the main decomposition zone) and 38%, respectively.

来自塑料废物的热解的炭占释放的热解产物的约20重量％。为了使该馏分的经济利益和应用最大化，本研究旨在将塑料废料中的焦炭提炼和再加工成碳颗粒，然后将其用作轻质材料应用中的微填料材料。实验是对金属化食品包装塑料废料（MFPW）的热解炭进行的，该废料代表了塑料废料中最复杂的部分，其炭中通常含有铝元素。实验开始于在热解装置中处理250 g的MFPW，然后将焦炭与其他热解产物分离。将衍生的焦炭进行研磨处理，然后进行浸提处理以分离Al馏分和其他重金属。将释放的碳颗粒暴露于功能化过程中，以去除任何污染物和无定形杂质。球形微粒（FBC：0.25、0.5、0.75和1 wt。％）形式的功能化炭黑颗粒用于增强玻璃纤维/环氧树脂复合层压板的机械冲击和热性能。复合板使用真空辅助树脂转移和固化工艺制备。使用SEM-EDS和FTIR检查了FBC的形态和组成。另外，使用SEM和光学显微镜观察FBC的分散，组织的微观结构，冲击机理和表面形态。面板的机械性能和冲击性能分别根据ASTM-D7025和ISO 6603-2标准进行了测试。最后，使用热重分析研究了面板的热行为。结果表明，与纯样品相比，0.75 wt。％的FBC足以将面板的弹性模量提高约22％。此外，在相同浓度的FBCs下，热稳定性和能量冲击吸收分别提高了21％（在主分解区）和38％。
