This study presented a novel utilization of biomass solid waste, named Polyalthia longifolia (Mast tree) seed as a reinforcement in a composite, using a compression molding technique. An attempt was made to reinforce vinyl ester matrix (VE) with Polyalthia longifolia seed filler (PLSF), ranging from 5 to 50 wt% loadings. Mechanical properties of the fabricated Polyalthia longifolia seed filler/vinyl ester (PLSF-VE) composite samples were tested and analyzed. The results showed that the PLSF-VE composite exhibited optimum mechanical properties at 25 % wt of filler loading; ultimate tensile strength and modulus were approximately 32.50 MPa and 1.23 GPa, respectively. The ultimate flexural, impact strengths and hardness were observed around 125 MPa, 31.09 kJ/m² and 36.50, respectively. The heat deflection test and thermo-gravimetric analysis depicted that the PLSF-VE composites withstood up to 66 °C and 430 °C, respectively. Furthermore, the PLSF and its various composite samples were studied, using energy-dispersive X-ray (EDX), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM).

这项研究提出了一种新的利用生物质固体废物的方法，即利用压缩成型技术，将名为Polyalthia longifolia（肥大树）种子作为复合材料的增强材料。有人企图加强乙烯基酯矩阵（VE）与垂枝暗罗种子填料（PLSF），范围从5至50重量％的负载量。测试并分析了制作的长白花种子填料/乙烯基酯（PLSF-VE）复合材料样品的机械性能。结果表明，PLSF-VE复合材料在25％wt的填料填充量下表现出最佳的力学性能。极限抗拉强度和模量分别约为32.50 MPa和1.23 GPa。在125 MPa（31.09 kJ / m）附近观察到极限挠曲，冲击强度和硬度²和36.50。热变形测试和热重分析表明，PLSF-VE复合材料分别承受了66°C和430°C的高温。此外，使用能量色散X射线（EDX），X射线衍射（XRD），傅里叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）对PLSF及其各种复合样品进行了研究。
