The selection of suitable composite material for high-strength industrial applications, from the list of available alternatives, is a tedious task as it requires an optimized structural performance-based solution. This study aimed to optimize the concentration of fillers, i.e., vinyl tri-ethoxy silane and absorbed gamma-dose, to enhance the properties of an industrial scale polymer, i.e., ultra-high molecular weight polyethylene (UHMWPE). The UHMWPE hybrids, in addition to silane, were treated with (30, 65, and 100 kGy) gamma dose and then tested for ten application-specific structural and performance attributes. The relative importance of attributes based on an 11-point fuzzy conversation was used for establishing the material assessment graph and corresponding adjacency matrix. Afterwards, the normalized values of attributes were used to establish the decision matrix for each alternative. The normalization was performed after the identification of high obligatory valued (HOV) and low obligatory valued (LOV) attributes. After this, suitability index values (SIVs) were calculated for ranking the hybrids that revealed hybrids 65 kGy irradiated the hybrid as the best choice and ranked as first among the existing alternatives. The major responsible factors were higher oxidation strength, a dense cross-linking network, and elongation at break. The values of the aforementioned factors for 65 kGy irradiated hybrids were 0.24, 91, and 360 MPa, respectively, as opposed to 0.54, 75, and 324 MPa for 100 kGy irradiated hybrids, thus placing the latter in second place regarding higher values of Yield Strength and Young Modulus. Finally, it is believed that the reported results and proposed model in this study will improve preoperative planning as far as considering these hybrids for high-strength industrial applications including total joint arthroplasty, textile-machinery pickers, dump trucks lining ships, and harbors bumpers and sliding, etc.
从可用的替代材料列表中选择适合高强度工业应用的复合材料是一项繁琐的任务，因为这需要基于优化结构性能的解决方案。本研究旨在优化填料（即乙烯基三乙氧基硅烷）的浓度以及吸收的伽马剂量，以提高工业规模聚合物（即超高分子量聚乙烯，UHMWPE）的性能。除硅烷外，UHMWPE杂化材料还接受了（30、65和100千戈瑞）的伽马剂量处理，然后针对十个特定应用的结构和性能属性进行测试。基于11点模糊对话的属性相对重要性用于建立材料评估图和相应的邻接矩阵。之后，使用属性的归一化值为每个替代方案建立决策矩阵。归一化是在确定高强制值（HOV）和低强制值（LOV）属性之后进行的。在此之后，计算适用性指数值（SIV）以对杂化材料进行排名，结果显示65千戈瑞辐照的杂化材料是最佳选择，在现有替代方案中排名第一。主要的影响因素是较高的氧化强度、致密的交联网络和断裂伸长率。65千戈瑞辐照杂化材料的上述因素值分别为0.24、9 和360兆帕，而100千戈瑞辐照杂化材料的相应值为0.54、75和324兆帕，因此就屈服强度和杨氏模量的较高值而言，后者位居第二。最后，相信本研究报告的结果和提出的模型将改善术前规划，即在考虑将这些杂化材料用于包括全关节置换术、纺织机械投梭器、自卸卡车衬里、船舶和港口缓冲器及滑动装置等高强度工业应用方面。
