This research focused on the fabrication of flame‐retardant green composites by utilizing inexpensive bio‐waste eggshell powder (ESP) as a flame‐retardant additive to polypropylene (PP)/abaca fibers (AF) composites (AF/ESP‐PP). The optimization of AF reinforcement in composites examines various wt% (5‐20) of fibers in the light of mechanical properties. Fifteen weight percentage of AF reinforcement showing the highest tensile (26 MPa) and flexural (46 MPa) strength compared to the remaining composites. Spectral (Fourier‐transform infrared spectroscopy) and micro (scanning electron microscope) analysis support the improvement of mechanical strength of the composites in connection with the interaction between AF with PP. Besides, different wt% (2, 4, 6, and 8) of ESP were incorporated into the AF/PP composites and examine the thermal and flame‐retardant properties by thermogravimetric analysis, horizontal burn test, and microcalorimetry, respectively. An improvement in thermal stability 9.82 wt% at 700°C, horizontal burn test results and decrement in peak heat release rate to 947 W/g.

聚丙烯/蕉麻纤维生态复合材料：生物废料添加剂对阻燃性和机械性能的影响

这项研究致力于通过利用廉价的生物垃圾蛋壳粉（ESP）作为聚丙烯（PP）/蕉麻纤维（AF）复合材料（AF / ESP-PP）的阻燃添加剂，来制造阻燃绿色复合材料。复合材料中AF增强的优化根据机械性能检查了各种wt％（5-20​​）的纤维。与其余复合材料相比，AF增强材料的15重量百分比显示出最高的拉伸强度（26 MPa）和弯曲强度（46 MPa）。光谱（傅里叶变换红外光谱）和显微（扫描电子显微镜）分析支持与AF和PP之间的相互作用相关的复合材料机械强度的提高。此外，不同的wt％（2、4、6，和8）的ESP被掺入到AF / PP复合材料中，并分别通过热重分析，水平燃烧试验和微量量热法检查其热和阻燃性能。在700°C下的热稳定性提高了9.82 wt％，水平燃烧测试结果得到改善，并且峰值放热速率降低到947 W / g。
