What is natural fibre composites?4 answersNatural fiber composites (NFCs) are composite materials made from renewable resources, combining reinforcing fibers from plants like jute, flax, hemp, and others with a matrix, often derived from biomass. These composites offer a sustainable alternative to conventional materials, addressing environmental concerns and the need for lightweight, low-carbon footprint materials. NFCs exhibit excellent mechanical properties, making them suitable for various applications in industries such as automotive, aerospace, and furniture. To enhance compatibility between the fibers and the polymer matrix, surface modifications like chemical treatments are often necessary. The utilization of NFCs is on the rise, with industries shifting towards sustainable alternatives due to diminishing petroleum reserves and the eco-friendly nature of natural fibers.
What the highest impact strength of natural fiber composite?5 answersThe highest impact strength of natural fiber composites was found to be 54 kJ/m2 in a study involving flax and glass fiber-reinforced laminates. Another research highlighted that the impact strength of flax fiber-reinforced composites reached 44 J/m for 7 layers, while jute fiber composites had a lower impact strength of 37 J/m for 5 layers. Additionally, a study on composites using pine needle fibers and pistachio shell fillers reported an increase in impact strength compared to neat epoxy samples, with the highest impact strength of 23.33 kJ/m2 observed in a hybrid composite with natural fillers and pine needle fibers.
