Abstract
A composite material comprising a polymer and a carbonized hemp filler, wherein the carbonized hemp filler is produced by carbonizing hemp at a temperature of at least 1100 C to produce a char; and milling the char to produce a particle size, wherein the filler comprises 95% of particles of less than 10 microns in size; and wherein the hemp filler comprises between 1 and 50% of the total mass of the composite.
Claims15
A composite material comprising a polymer and a hemp char filler, wherein the hemp char filler is produced by carbonizing a portion of hemp at a temperature of at least 1100° C. to produce a hemp char;
- and milling the hemp char to produce the hemp char filler having an average particle size of between 0.001 and 10 microns;
- adding into hemp char filler a portion of polymer and milling the hemp char filler and polymer together to form the composite material, wherein the hemp char filler comprises 95% of particles of between 0.001 and 10 microns in size;
- and wherein the hemp char filler comprises between 1% and 50% of the total mass of the composite material;
- and wherein the composite does not contain silanes or a dispersing agent to disperse the hemp particles into the polymer before forming the composite material.
A method of manufacturing a hemp based composite particles comprising:
- processing a portion of polymer to generate a polymer particle having an average particle size of between 0.001 and 10 microns, using a 30 Hz processing in an oscillating mill;
- processing a portion of hemp by cryomilling said hemp under liquid nitrogen at 30 Hz;
- and combining a portion of the polymer particle and a portion of the cryomilled hemp and milling them together at 30 Hz to form composite particles.
