Structure
The structure of a bio-composite material typically consists of two
main components: a polymer matrix and reinforcing fibers derived
from natural sources.
Polymer Matrix:
Reinforcing Fibers:
The polymer matrix is typically a
include polylactic acid (PLA),
polyhydroxyalkanoates (PHA),
polybutylene succinate (PBS), and
other biodegradable polymers.

The reinforcing fibers are derived from natural
sources, such as plants or agricultural waste.

Common natural fibers used include jute, flax,
hemp, kenaf, sisal, and cotton, among others.

Serves as the base material that
holds the reinforcing fibers to the
composite structure.


It contributes to the biodegradability
and environmental friendliness of
the material.
These fibers are incorporated enhance the
mechanical properties of the composite, such
as tensile strength, stiffness, and impact
resistance.

The orientation and distribution of these fibers
within the polymer matrix can be tailored to
achieve specific performance characteristics.

Classification
Composition

Coupling Agents:

In some bio-composite formulations, coupling agents or compatibilizers may
be added to enhance the adhesion between the polymer matrix and natural
fibers.

Coupling agents can improve the overall mechanical properties and durability
of the material.

Fillers or Additives:

Depending on the application and desired properties, bio-composites may
include various additives or fillers, such as fire retardants, antioxidants,
colorants, and other functional additives.
Processing Method

The components of the bio-composite are typically combined
using various processing methods including:
1.
Compression molding
2.
Injection molding
3.
Extrusion
The choice of processing method can influence the distribution
and orientation of the reinforcing fibers within the polymer
matrix.
Manufacturing Of Biomass Based
Polypropylene
Biomass-based polypropylene is a type of polypropylene plastic that
is derived from renewable biomass sources, such as plants, rather
than from fossil fuels.
Process involve:
This can be achieved through processes like :

gasification

fermentation

other bio-based routes
