” Bamboo has nearly the same strength as a mild steel while showing more versatility,” says Dr. Milani, the founding director of the Materials and Manufacturing Research Institute. “With its low weight, expense, and plentiful availability, bamboo is a product that has terrific pledge but previously had one big downside.”
Bamboo is one of the worlds most collected and used natural fibers with more than 30-million tonnes produced annually. Its natural fibers can absorb water and break down and deteriorate over time due to wetness uptake and weathering.
Using a procedure called plastination to dehydrate the bamboo, the research group then use it as a reinforcement with other fibers and products. Then they cure it into a new high-performance hybrid biocomposite.
Established by Gunther von Hagens in 1977, plastination has actually been extensively utilized for the long-term conservation of animal, human and fungal remains, and now has actually found its way to innovative products applications. Plastination ensures toughness of the composite material for both brief- and long-lasting usage, states Daanvir Dhir, the reports co-author and recent UBC Okanagan graduate.
” The plastinated-bamboo composite was combined with glass and polymer fibers to develop a material that is lighter and yet more durable than comparable composites,” states Dhir. “This work is distinct as there are no earlier studies investigating using such plastinated natural fibers in artificial fiber strengthened polymer composites.”
Dhir states this new resilient hybrid bamboo/woven glass fiber/polypropylene composite, treated with the plastination strategy has a promising future.
Supported by industrial partner NetZero Enterprises Inc., the research study shows that including just a small quantity of plastinated products to the bamboo can increase the effect absorption capacity of the composite– without losing its flexible homes. This likewise reduces the products destruction rate.
More work needs to be done on the optimization of this process as Dhir says plastination is currently lengthy. He notes the advantage of finding the best structure of plastinated natural fibers will result in a substantial decrease of non-degradable waste in many industries, with a lower ecological footprint.
Future research studies are underway to investigate the effect and optimize of plastinating other natural fibers, such as flax and hemp. The scientists also suggest a life process analysis of the products must be carried out under different applications and compared to non-plastinated samples. This will supply a much better image of the corresponding compromise in between the ecological footprint and mechanical durability impacts.
” Biocomposites continue to find new applications under the circular economy paradigm,” includes Dr. Milani. “The developments in the methods utilized to establish these composites will make sure benefits well into the future.”
The research study appears in the Journal Composite Structures.

A respected plant, bamboo has actually long been considered a good building material in numerous countries. Now, UBC Okanagan scientists have actually created a way to make it even stronger.
When used to maintain bodies, plastination now strengthens biocomposites.
UBC Okanagan scientists have adapted a method– originally developed to embalm human remains– to reinforce the homes of biocomposites and make them stronger.
With the development of green composites and new materials, it is simple to neglect products like bamboo and other natural fibers, discusses UBCO Professor of Mechanical Engineering Dr. Abbas Milani. These fibers are now utilized in many applications such as clothing, the vehicle market, packaging, and building and construction.
His research study group has actually now found a method not only to strengthen these fibers, but decrease their tendency to degrade over time, making them much more eco-friendly.
