Allium sativum fiber has a high cellulose content of 69.82% and a low density of 1.32 g/cc. In the present study, various chemical treatments, namely, alkaline, benzoylation, and acetylation were carried out to enhance its properties. The effect of chemical treatments on the fiber and its effect on various properties of the brake pad is studied. Allium sativum raw fiber (ASRaw), alkaline-treated (ASa), benzoylation-treated (ASb), and acetylation treated-fibers (ASac) were reinforced for about 8 wt.% in the brake pads that were manufactured using compression molding and named as AS1, AS2, AS3, and AS4, respectively. The thermal degradation of the fiber is evaluated using thermogravimetric analysis (TGA) and is observed the thermal stability from 340°C to 359°C, 360°C, and 378°C, respectively. From X-ray diffraction (XRD), it was found that acetylation-treated fiber had shown a crystallinity index (CI) of 35.86% with a tensile strength of 723.28 ± 2.7 MPa. Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM) were used to study the organic substance behavior and surface morphology. The physical, thermal, and mechanical properties of the brake pads were carried out as per industrial standards.

葱属植物纤维纤维素含量高,为69.82%,低密度为1.32 g/cc. 在本研究中,我们进行了各种化学处理,即碱化、苯甲酰化和乙酰化,以提高其性能. 研究了化学处理对纤维的影响及其对刹车片各项性能的影响. 在采用模压成型工艺生产的刹车片中,分别添加了大蒜粗纤维(ASRaw)、碱处理(ASa)、苯甲酰化处理(ASb)和乙酰化处理(ASac),增强强度约为8 wt. %,分别命名为AS1、AS2、AS3和AS4. 采用热重分析法(TGA)对纤维的热降解进行了评价,并分别在340◦C至359◦C、360◦C和378◦C的温度下观察了纤维的热稳定性. X射线衍射(XRD)结果表明,经乙酰化处理的纤维结晶度指数(CI)为35.86%,抗拉强度为723.28±2.7 MPa. 利用傅里叶变换红外光谱(FT-IR)和扫描电镜(SEM)研究了有机物的行为和表面形貌. 根据工业标准对刹车片进行了物理、热学和力学性能测试.
