Bio resins are obtained from renewable sources such as vegetable oils, starch or sugars, and are produced through low energy impact processes. These resins, such as those based on polylactic acid (PLA) or vegetable polyurethanes, have mechanical properties comparable to traditional petroleum-based resins, but with the advantage of being biodegradable and recyclable.
Alongside bio resins, natural fibers are gaining more and more space as reinforcement for composite materials. In particular, linen fiber stands out for its high performance and low environmental impact. This fibre, obtained from the processing of the flax plant, offers:


• good mechanical resistance
• low density
• excellent thermal and acoustic insulation
• biodegradability and recyclability

Polymer matrix composites reinforced with flax fiber are used in numerous applications, such as the automotive industry for the production of interior panels, construction for thermal and acoustic insulation, and the furnishing sector for the production of furniture and furnishing.
In addition to flax fibres, other natural fibers such as hemp, jute and kenaf are used in the creation of bio-composite materials, offering sustainable solutions for a wide range of applications.
The use of resins and natural fibers in composite materials represents an important step towards a greener future. These bio materials, in addition to reducing environmental impact, offer competitive performance and low costs, making them an increasingly attractive choice for producers and consumers attentive to sustainability.
