Co to jest?

Biocomposite materials are advanced composites formed combinang natural consigning fibers - such as hemp, flax, jute, kenaf, sisal, or bamboo - with a polymer matrix. Thee matrix can either a biodegrade dable resin (np., polilactic acid) or a fossil- fuel- based plastic that is exparted with natural fibers to reduce overtal petroleum content.

Performance Advantages

Lightweighting andFuel Efficiency

Bio-composites are typically 15- 30% lighter than equivalent glass- fiber composites and up to 50% lighter than steel in certain interior applications. Reducing vehicles directly improwites fuel economy andd extends the range of electric vehigles.
