The company works on the development of various biopolimere materials and with the combination of such materials we also manufacture the resulted so-called biocomposite materials.
Another great advantage over the modern composite materials is, that is also absorbs vibration and creates a support effect in a composite system (Which proposes new structural innovation possibilities). The first biocomposite materials were used in the ancient-times and the first tool utilizing such technology was the composite-bow.
It was made of the combination of horns, wood, tendons, adhesive and bones. Tendons are rugged to fibers and after a special treatment are soaked in adhesive and are finally dried. They were made similar like a modern fiber epoxy sheet.
As a sole entrepreneur I’ve been manufacturing bows for over twenty years from horn and tendon.
The idea of utilizing biocomposite materials was never far from me.
We’ve gathered a deep insight into material science by spending years with the different segments of it.
The most raw materials for our bows were developed by us that also involve the modern and synthetic composite materials.
The real thrust that we achieved when ‘Naturcomposite LLC’ was founded was the discovery of the technique how particular glues made from natural raw materials can be made highly water resistant with increased strength.
The word ‘Biocomposite’ as its name may reflect means the combinations of multiple components that disintegrate (with time in nature) to achieve a new stronger combined material with better features.
We’ve made researches with various biopolymers that may have different initial materials.
A few possible biocomposite materials:
The silk of the spider is a very strong material, also hard to gather, but contains the same fibrin whey as for example the blood of the cattle. If different steel oxides are combined with the fibrin of cattle blood, and are made to form a matrix, a very strong and resistant material can be achieved, that is also suitable to substitute natural bones.
Another albumin that can result in porcelain like material is a calcium-albuminate matching with the one found in sea oysters.
With the mixture of animal- and plant whey combined with chemically modified horn wastage, a material with very similar features can be achieved like the horn sheet.
Corn starch can be used to produce packing foil that degrades easily.
By brewing corn, alcohol and so called PLA plastic can be produced that degrade easily. It is mainly suitable as packaging material, as it is softened by heat and is not mechanically solid.
A so called material ‘Zein’ can be extracted from corn whey that from soy with expansion a sponge-like material can be created that degrades.
From the materials listed above, strengthened fiber and matrix materials can also be created, or can solely be used.
To achieve their best features it is a must to combine various materials with different procedures.
The know-how of the procedure highly influences the quality and features of the final product.
The features of the fiber strengthened biocomposite materials are the most significant.
Fibers found in nature, for e.g. flax and hemp are unfortunately not suitable to create a perfect biocomposite material,
as they not adhere to matrix materials and their flexibility indicators are also not satisfactory.
With specific procedures, natural carbon fibers can be created that can be successfully combined with biopolymers,
with high flexibility modulus and low weight, like plastic based carbonized fibers.
Weight indicators show 0,9 gram/ cm3 compared to 1,7 gram/cm3.
Of course with other procedures there are other natural fibers that can be used to achieve new natur-composite materials with perfect features.
Such natur-composite and biocomposite raw materials can be advantageous at many fields, but we concentrate on Manufacturing sports equipment.
Apart from the main profile we also constantly research the different possible opportunities for these materials to be used.
Such fields, for e.g.:
- Vehicle dashboard and other component panels
- Packaging material that degrade in nature
- Plastic trays in fast food restaurants.
- As insulation against current such as light switches or backpanel of mobile phones
Some biocomposite materials are extraordinarily spectacular and decorative, can be half transparent, when touched their natural origin can also be felt.
Technically, due to their high strength they are suitable for mechanically stressed products as well.
As a result of the above, another activity of the firm is the development and manufacturing of bicycles.
What is a ‘biopolimere’? What does ‘biocomposite’ mean?
The different composite materials are already wide spread in the industry nowadays, such as carbon fiber or glass-fiber combined with synthetic resin.
The biggest disadvantage of such materials is that they almost never disintegrate in nature. On the other hand their strength / weight ratio and the durability are both significant.
A biocomposite material disintegrates in nature; however it is still light and very strong mechanically.
