Three-dimensional reinforcement of woven advanced polymer–matrix composites using aligned carbon nanotubes (CNTs) is explored experimentally and theoretically.
Radially-aligned CNTs grown in situ on the surface of fibers in a woven cloth provide significant three-dimensional reinforcement, as measuredby Mode I interlaminar fracture testing and tension-bearing experiments.
Aligned CNTs bridge the ply interfaces giving enhancement in both initiation and steady-state toughness, improving the already tough system by 76% in steady state (more than 1.5 kJ/m2 increase).

Bio-Based Orange Peel Epoxy Resins

Nisan 17, 2022

Portakal yağından yapılan biyo-bazlı epoksi reçinelerin gelecekte raylı araçlarda, spor ekipmanlarında, otomobillerde, mimaride, gemi yapımında ve iç tasarımda çok çeşitli uygulamalara hizmet etmesi beklenmektedir. Ayrıntılı bilgi  aşağıda yer almaktadır.

Sustainable alternatives are needed to reduce the use of petroleum-based polymers. The international project OrangeOil, in which the Fraunhofer IMWS is also involved in addition to the SKZ plastics center, provides a promising approach. The aim is to develop a bio-based epoxy resin system from orange peels – a residue from the production of juice and jam.
The hitherto widespread use of petroleum-derived polymers is becoming increasingly problematic. The bioeconomy approach is intended to provide more sustainable solutions, so that products are manufactured using renewable raw materials, biological residues and innovative processes. Natural oils and their extraction from organic waste and production residues are of particular interest for the chemical industry. They do not have to be obtained directly from crops or energy crops and do not compete for arable land for primary food production. The OrangeOil project meets these requirements and develops epoxy resin systems based on orange oil from orange peels. The project wants to make a contribution to the development of new production technologies and new materials for the processing industry and to meet both economic requirements and requirements for climate and environmental protection.
Wide range of applications for bio-based epoxy resins
Bio-based epoxy resins made from orange oil should in future serve a wide range of applications in rail vehicles, sports equipment, automobiles, architecture, shipbuilding and interior design. OrangeOil’s goal is to develop a bio-based two-component system for special applications, such as use as a pure resin layer in floor coverings and as a matrix component in fiber composite materials. The combination of the resin with natural fibers in biocomposites is considered particularly attractive due to its properties such as low density, high specific stiffness and the sustainability of the raw materials.
As part of the project, the partners SKZ, Fraunhofer Institute for Microstructure of Materials and Systems (IMWS) and TÜBITAK Marmara Research Center are investigating the production and handling of the resin and hardener components. After making the orange oil, it is epoxidized and used to make samples (pure resin and reinforced plastics). The bio-based resins and fiber-reinforced plastics are comprehensively characterized. The biogenic material is matched to the processing technology in order to ensure a reproducible process control through the creation of robust technical rules.
Interested companies can participate
The OrangeOil project started on October 1, 2021. Interested companies are invited to participate free of charge in the project-related committee of the OrangeOil research project (NR 299 EGB), to help shape the investigations and to find out about the current results. The project is funded as part of the CORNET program (Collective Research Networking). The initiative networks national and regional joint research programs from different countries in order to enable international research projects for the benefit of small and medium-sized companies. In Germany, CORNET is based on the joint industrial research (IGF) funded by the Federal Ministry for Economic Affairs and Climate Protection (BMWK).
