Abstract

A composite product includes basalt fibers and a liquid polymer resin mixed with a curing agent and infused into the basalt fibers. A method of making the composite product includes mixing a liquid polymer resin with a curing agent to form a resin matrix; infusing the resin matrix into basalt fibers; and curing the basalt fibers infused with the resin matrix to form the composite product. The method may further include adding an additive including at least one of graphene or graphite to the liquid polymer resin and the curing agent, and mixing the additive with them to form the resin matrix which is infused into the basalt fibers. It may further include weighing the additive, at about 0.1% to 0.3% of a weight of the liquid polymer resin and curing agent, to be added to the liquid polymer resin and curing agent.

First claim

What is claimed is:

1 . A composite product comprising:
basalt fibers; and a liquid polymer resin mixed with a curing agent and infused into the basalt fibers.

2 . The composite product of claim 1 , further comprising:
an additive including at least one of graphene or graphite mixed with the liquid polymer resin and the curing agent and infused into the basalt fibers.

3 . The composite product of claim 2 ,
wherein the additive is weighed at about 0.1% to 0.3% of a weight of the liquid polymer resin and curing agent.

4 . The composite product of claim 2 ,
wherein the additive includes at least one of graphene nanoparticles or graphite nanoparticles.

5 . The composite product of claim 1 ,
wherein the basalt fibers are provided as a basalt fibers fabric which is infused with the liquid polymer resin mixed with the curing agent and cured to form a composite panel.

6 . The composite product of claim 1 ,
wherein the liquid polymer resin comprises at least one of thermoset epoxies or aliphatic amines.

7 . The composite product of claim 1 ,
wherein the liquid polymer resin comprises DGEBF, hydrogenated DGEBF, and neopentyl glycol diglycidyl ether, and the curing agent comprises TETA.

8 . A method of making a composite product, the method comprising:
mixing a liquid polymer resin with a curing agent to form a resin matrix; infusing the resin matrix into basalt fibers; and curing the basalt fibers infused with the resin matrix to form the composite product.

9 . The method of claim 8 , further comprising:
adding an additive including at least one of graphene or graphite to the liquid polymer resin and the curing agent; and mixing the additive with the liquid polymer resin and the curing agent to form the resin matrix which is infused into the basalt fibers.

10 . The method of claim 9 , further comprising:
weighing the additive, at about 0.1% to 0.3% of a weight of the liquid polymer resin and curing agent, to be added to the liquid polymer resin and curing agent.

11 . The method of claim 9 ,
wherein the additive includes at least one of graphene nanoparticles or graphite nanoparticles.

12 . The method of claim 8 , further comprising:
forming a basalt plain weave fabric of the basalt fibers which is infused with the liquid polymer resin mixed with the curing agent; and curing the infused basalt plain weave fabric to form a composite panel.

13 . The method of claim 12 , further comprising:
laying up the basalt plain weave fabric by hand which is infused with the liquid polymer resin mixed with the curing agent.

14 . A composite product made by the method of claim 8 .

15 . A composite product made by the method of claim 8 which further comprises:
adding an additive including at least one of graphene or graphite to the liquid polymer resin and the curing agent; and
mixing the additive with the liquid polymer resin and the curing agent to form the resin matrix which is infused into the basalt fibers.

16 . A composite product made by the method of claim 8 which further comprises:
weighing an additive, at about 0.1% to 0.3% of a weight of the liquid polymer resin and curing agent, to be added to the liquid polymer resin and curing agent, the additive including at least one of graphene or graphite; and
mixing the additive with the liquid polymer resin and the curing agent to form the resin matrix which is infused into the basalt fibers.

17 . The composite product of claim 16 ,
wherein the additive includes at least one of graphene nanoparticles or graphite nanoparticles.

18 . A composite product made by the method of claim 8 which further comprises:
laying up a basalt plain weave fabric of the basalt fibers by hand which is infused with the liquid polymer resin mixed with the curing agent; and
curing the infused basalt plain weave fabric to form a composite panel.

19 . A composite product made by the method of claim 8 ,
wherein the liquid polymer resin comprises at least one of thermoset epoxies or aliphatic amines.

20 . A composite product made by the method of claim 8 ,
wherein the liquid polymer resin comprises DGEBF, hydrogenated DGEBF, and neopentyl glycol diglycidyl ether, and the curing agent comprises TETA.
