This paper examines the use of post-consumer denim fabric in combination with thermoset bio-resins in composite manufacturing for structural applications. Bio-epoxy and acrylated epoxidized soybean oil resin (AESO) were used as bio-resins with four different manufacturing techniques in order to create a wide scope of possibilities for research. The four techniques are: compression moulding (COM), vacuum infusion (VAC), resin transfer moulding (RTM) and hand lay-up (HND). The bio-resins were compared to a conventional polyester resin, as this is highly used for structural applications. To determine suitability for structural applications, the biocomposites were tested for their mechanical and thermal properties. Fabricated composites were characterised regarding porosity, water absorption and analysed through microscopic images of the composite. Results show both bio-epoxy and AESO are suitable for use in structural applications over a range of manufacturing techniques. Furthermore, biocomposites from bio-epoxy are superior to those from AESO resin. The conventional polyester has shown to be unsuitable for structural applications.

本文研究了消费后牛仔布与热固性生物树脂在结构应用复合材料制造中的结合使用。生物环氧树脂和丙烯酸酯化的环氧大豆油树脂（AESO）被用作具有四种不同制造技术的生物树脂，从而为研究提供了广泛的可能性。这四种技术是：压缩成型（COM），真空灌注（VAC），树脂传递成型（RTM）和手工铺网（HND）。将生物树脂与常规聚酯树脂进行了比较，因为该树脂高度用于结构应用。为了确定对结构应用的适合性，对生物复合材料的机械和热性能进行了测试。对制成的复合材料的孔隙率，吸水率进行表征，并通过复合材料的显微图像对其进行分析。结果表明，生物环氧和AESO均适用于一系列制造技术中的结构应用。此外，来自生物环氧树脂的生物复合材料优于来自AESO树脂的生物复合材料。常规聚酯已显示不适合结构应用。
