This work investigates composites from renewable resources that exhibit high flexibility. The effect of three different weft-knitted structures on the tensile properties, flexural tear resistance and puncture impact properties is analyzed in combination with two flexible matrix materials. Furthermore, potential knitted compared to a woven fabric comprehensively discussed. total absorbed energy tests were unaffected by material. Among structures, highest strength, achieved interlock...
Abstract This work describes the development and characterization of mechanical flexible epoxy resins based on epoxidized vegetable oils (EVO) sebacic acid. Different oil types (linseed oil, hempseed soybean oil) with varying equivalent weight (EEW) were used. Formulation processing parameters systematically optimized by differential scanning calorimetry Fourier‐transform infrared spectroscopy. The effect EVO type EEW thermo‐mechanical properties investigated dynamic analysis tensile tests...
In this work, the concept of fracture toughness improvement via spatial variation mechanical properties is applied to a composite with 100% bio-based carbon content based on epoxidized linseed oil. By proper selection hardener, either citric acid or sebacic acid, were adjusted in way that bio-composite exhibits stiff-soft-stiff layer architecture. Samples two different thicknesses soft interlayer (approx. 0.1 mm and 1.3 mm) subsequently analyzed regarding their final performance. Specimen...
Abstract The tensile behavior of a flexible epoxy resin reinforced with knitted reinforcements from various fiber materials was comprehensively studied in the wale and course direction. By measuring dry yarns, temperature‐treated fabrics composites, effect material fabric on properties analyzed. interlock knit structure strongly affected deformation composites which differed significantly fabrics. monitored using digital image correlation revealed formation cracks high local strain...
