Abstract

The main objective of this study is to compare the interpenetrating polymer networks’ (IPNs) physical strengths with different variants of fibers. In this study, E-glass, carbon, and a combination of E-glass and carbon fiber (hybrid) have been taken as the reinforcement. Similarly, three combinations of the IPNs were chosen as the matrix material, namely epoxy / polyurethane (EP), vinyl ester / polyurethane (VP) and epoxy/vinyl ester (EV) as IPN blends. In order to thoroughly understand the physical characteristics of the combination of blends and fibers, nine variants (laminates) were fabricated: combinations of epoxy / polyurethane / E-glass (EPG), epoxy / polyurethane / carbon (EPC), epoxy / vinyl ester / glass / carbon (EPGC-hybrid), vinyl ester / polyurethane / glass (VPG), vinyl ester / polyurethane / carbon (VPC), vinyl ester / polyurethane / glass / carbon (VPGC), epoxy / vinyl ester / glass (EVG), epoxy / vinyl ester / carbon (EVC), and epoxy / vinyl ester / glass / carbon (EVGC-hybrid), all with help of a hand-layup technique. Furthermore, mechanical tests such as tensile, flexural, impact, and HDT (heat distortion temperature) were performed on all the variants as per the ASTM standards. Results shows that carbon fiber reinforcement with all IPN combinations has shown extraordinary performance (double fold) over the E-glass fiber reinforcement, whereas the hybrid (combination of E-glass/carbon) laminates have shown excellent characteristics over E-glass fiber reinforcement, irrespective of IPN matrix material. All the results were compared with each other and their corresponding variations were plotted as bar charts.

Begitu juga, tiga kombinasi IPN dipilih sebagai bahan matrik, iaitu epoksi / poliuretan (EP), ester vinil / poliuretan (VP) dan epoksi / ester vinil (EV) sebagai campuran IPN.

ipns(乙烯/环氧/聚氨酯)对玻璃/碳纤维增强复合材料力学性能的影响

本研究的主要目的是比较不同纤维变体的互穿聚合物网络(ipn)的物理强度。本研究采用e -玻璃、碳纤维以及e -玻璃与碳纤维的复合材料(混杂)作为增强材料。同样，我们选择了三种IPN组合作为基体材料，即环氧树脂/聚氨酯(EP)、乙烯基酯/聚氨酯(VP)和环氧树脂/乙烯基酯(EV)作为IPN共混物。为了彻底了解共混物和纤维组合的物理特性，制备了9种变体(层压板):环氧树脂/聚氨酯/ e -玻璃(EPG)、环氧树脂/聚氨酯/碳(EPC)、环氧树脂/乙烯基酯/玻璃/碳(EPGC-hybrid)、乙烯基酯/聚氨酯/玻璃(VPG)、乙烯基酯/聚氨酯/碳(VPC)、乙烯基酯/聚氨酯/玻璃/碳(VPGC)、环氧树脂/乙烯基酯/玻璃(EVG)、环氧树脂/乙烯基酯/玻璃/碳(EVC)和环氧树脂/乙烯基酯/玻璃/碳(EVGC-hybrid)的组合。此外，根据ASTM标准，对所有变体进行了拉伸、弯曲、冲击和HDT(热变形温度)等机械测试。结果表明，所有IPN组合的碳纤维增强材料都比e -玻璃纤维增强材料表现出非凡的性能(双倍)，而混合(e -玻璃/碳的组合)层叠板比e -玻璃纤维增强材料表现出优异的特性，而与IPN基体材料无关。将所有结果相互比较，并绘制相应的条形图。摘要:目的研究龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草、龙胆草等。卡坚尼蒙古那巴凯龙胆卡卡- e，卡坚丹加本甘卡卡- e丹龙胆卡卡(杂交)塞巴盖企鹅。Begitu juga, tiga kombinasi IPN dipilih sebagai bahan matrik, iitu epoksi / poliuretan (EP)， ester vinil / poliuretan (VP)和epoksi / ester vinil (EV) sebagai campuran IPN。Bagi tujuan memahami secara ciri- fizikal gabungan campuran dan gentian, sembilan varian (lamina) dihasilkan, malaui kombinasi seperti epoksi / poliuretan / kaca- e (EPG)， epoksi / poliuretan /碳(EPC)， epoksi /酯乙烯/ kaca /碳(epgc - hybrid)，酯乙烯/ poliuretan / kaca /碳(VPGC)， epoksi /酯乙烯/ kaca /碳(EVG)， epoksi /酯乙烯/ kaca /碳(EVC)，环氧/酯/乙烯/乙烯/碳(evgc -杂化)登革技术鉴定天然青金石蒙古纳肯唐甘。Selain itu, ujian mekanikal seperti tegangan, lenturan, hentaman danhdt (suhu kelenturan panas) dilakukan paas semua varian mengikut piawan ASTM。Dapatan kajian menunjukkan bahawa, penguin gentian karbon dengan semua kombinasi IPN, telah menunjukkan prestasi luar biasa (dua kali ganda) daripada企鹅gentian kaka - e, manakala lamina杂交(campuran kaka - e / karbon) telah menunjukkan ciri-ciri sangat baik berbanding企鹅gentian kaka - e tanpa mengira bahan matrik IPN。Semua hasil dapatan dibandingkan antara satu sama lain dan padanan varasi diplot sebagai carta bar。
