Study on Machining Parameters and Mechanical Properties of Hybrid Agave Sisalana and Glass Fiber-reinforced Polyester Composites (A/GFRP)

ABSTRACT

Agave fiber/polymer matrix composites have recently been used in automotive, aerospace, and construction field, where they will be secure for shape-made applications. Hand lay-up is used to make Agave and Glass fiber-reinforced polyester composites (A/GFRP), Agave fiber-reinforced polyester composites (AFRP), and Glass fiber-reinforced polyester composites (GFRP). The impact energy absorbed and tensile strength for A/GFRP material are higher than those for AFRP material. Drilling of GFRP, AFRP, and A/GFRP composites is carried out by using carbide twist drill D 5407060 of 6 mm diameter. Process parameters include two distinct speeds (800 rpm and 1200 rpm) and two distinct feeds (0.02 mm/rev and 0.04 mm/rev). The influences of processing parameters on thrust force and delamination while drilling GFRP, AFRP, and A/GFRP materials are investigated. For the optimum process parameter (feed = 0.02 mm/rev and 800 rpm) for GFRP, AFRP, and A/GFRP, the thrust force and delamination factor are limited at these feed rate conditions. In comparison to AFRP, delamination is minimum for A/GFRP drilled with carbide tools at lower feed rates as per microstructural examination. The Taguchi technique is used to determine the best feed and speed parameters for machining responses, and it demonstrates that acceptable values are achievable with A/GFRP.

摘要

龙舌兰纤维/聚合物基复合材料最近已被应用于汽车、航空航天和建筑领域, 在这些领域, 它们将安全地用于成型应用. 手糊用于制造龙舌兰和玻璃纤维增强聚酯复合材料 (A/GFRP) 、龙舌兰纤维增强聚酯复合材料 (AFRP) 和玻璃纤维增强聚酯复合材料 (GFRP). A/GFRP材料的冲击能量吸收和拉伸强度均高于AFRP材料. 使用直径为6mm的硬质合金麻花钻D5407060对GFRP、AFRP和A/GFRP复合材料进行钻孔. 工艺参数包括两种不同的速度 (800rpm和1200rpm) 和两种不同的进给 (0.02mm/rev和0.04mm/rev). 研究了加工参数对钻削GFRP、AFRP和A/GFRP材料时推力和分层的影响. 对于GFRP、AFRP和A/GFRP的最佳工艺参数 (进给=0.02mm/rev和800rpm), 推力和分层系数在这些进给速度条件下受到限制. 与AFRP相比, 根据微观结构检查, 使用硬质合金刀具在较低进给率下钻孔的A/GFRP的分层最小. 田口技术用于确定加工响应的最佳进给和速度参数, 并证明了A/GFRP可达到可接受的值.
