Bio-resins: new structural renewable materials for bio-composite applications

Cardona, Francisco (2012) Bio-resins: new structural renewable materials for bio-composite applications. In: 4th KKU International Engineering Conference: Driving Together Towards ASEAN Economic Community (KKU-IENC 2012) , 10-12 May 2012, Khon Kaen University, Thailand.


Bio-resins are an emerging industrial technology derived from natural renewable components such as Plant-based Oils. Bio-resins can be obtained from the epoxidation of Vegetable Oils, which creates suitable thermoset resins known as Epoxidized Vegetable Oils (EVO). This initial process can be followed by a 2nd chemical functionalization known as the acrylation process of the epoxidized oils, which generates the acrylated-type of bio-resins (AEVO). The current international interest on bio-resins stems largely from increasing regulation and public concern for a pollution-free environment and the need for sustainable alternatives to reduce the dependence on fosil fuels. The synthesized bio-resins can be used as the matrix of 100 % bio-composites with the application of Natural Fibers such as Flax, Hemp, Bamboo or Jute fibers between others, used as natural reinforcement to the bio-composites. At the Centre of Excellence in Engineered Fibre Composites (CEEFC– USQ university, Australia) we have been working in the last 10 years on the development and characterization of bio-composites. In a particular investigation we established the mechanical properties (tensile, flexural and Charpy impact resistance) of bio-composites made of epoxidized hemp oil (EHO) reinforced with natural Jute fibbers and synthetic Glass fibber mats. The EHO bio-resins were synthesized as world-first in the CEEFC laboratories. These bio-composites were investigated and compared with samples containing commercially produced epoxidized soybean oil (ESO) and a synthetic commercial epoxy resin. EHO based bio-resins and related bio-composites were found to have superior mechanical and impact resistance properties in comparison with equivalent structural materials made with the commercially available ESO bio-resins.
