Abstract

A composite material and a related method of manufacturing a component. The composite material may be comprised of plastic material in an amount between about 60% and about 70% by weight, cellulosic material in an amount between about 20% and about 30% by weight, and glass material in an amount up to about 20% by weight. The composite material may be injection molded to form a component.

Claims (72)

1. A method of manufacturing a component, said method comprising:

providing a composite comprising:

(a) plastic material in an amount between 63% and 67% by weight;

(b) cellulosic material in an amount between 20% and 30% by weight; and

(c) glass material in an amount between 0.1% and 20% by weight; and

injection molding said composite to form said component.

2. The method of claim 1 wherein said plastic material is in an amount of about 65% by weight.

3. The method of claim 1 wherein said plastic material is comprised of polyethylene.

4. The method of claim 1 wherein said cellulosic material is in an amount between 23% and 27% by weight.

5. The method of claim 1 wherein said cellulosic material is in an amount of about 25% by weight.

6. The method of claim 1 wherein said glass material is in an amount between 6% and 14% by weight.

7. The method of claim 1 wherein said glass material is in an amount of about 10% by weight.

8. The method of claim 1 wherein said glass material is comprised of fiberglass.

9. The method of claim 1 wherein said component is a spindle.

10. The method of claim 1 wherein said component is a post cap.

11. A method of manufacturing a spindle, said method comprising:

providing a composite comprising:

(a) polyethylene in an amount between 60% and 70% by weight;

(b) cellulosic material in an amount between 20% and 30% by weight; and

(c) glass material in an amount between 0.1% and 20% by weight; and

injection molding said composite to form said spindle.

12. The method of claim 11 wherein said glass material is comprised of fiberglass.

13. A spindle comprised of a composite, said composite comprising:

polyethylene in an amount between 60% and 70% by weight;

cellulosic material in an amount between 20% and 30% by weight; and

glass material in an amount between 0.1% and 20% by weight.

14. The spindle of claim 13 wherein said glass material is comprised of fiberglass.

15. A method of manufacturing a component, said method comprising:

providing a composite comprising:

(a) plastic material in an amount between 60% and 70% by weight;

(b) cellulosic material in an amount between 23% and 27% by weight; and

(c) glass material in an amount between 0.1% and 20% by weight; and

injection molding said composite to form said component.

16. The method of claim 15 wherein said plastic material is comprised of polyethylene.

17. The method of claim 15 wherein said cellulosic material is in an amount of about 25% by weight.

18. The method of claim 15 wherein said glass material is in an amount between 6% and 14% by weight.

19. The method of claim 15 wherein said glass material is in an amount of about 10% by weight.

20. The method of claim 15 wherein said glass material is comprised of fiberglass.

21. The method of claim 15 wherein said component is a spindle.

22. The method of claim 15 wherein said component is a post cap.

23. A method of manufacturing a spindle, said method comprising:

providing a composite comprising:

(a) plastic material in an amount between 60% and 70% by weight;

(b) cellulosic material in an amount between 20% and 30% by weight; and

(c) glass material in an amount between 0.1% and 20% by weight; and

injection molding said composite to form said spindle.

24. The method of claim 23 wherein said plastic material is in an amount between 63% and 67% by weight.

25. The method of claim 23 wherein said plastic material is in an amount of about 65% by weight.

26. The method of claim 23 wherein said cellulosic material is in an amount between 23% and 27% by weight.

27. The method of claim 23 wherein said cellulosic material is in an amount of about 25% by weight.

28. The method of claim 23 wherein said glass material is in an amount between 6% and 14% by weight.

29. The method of claim 23 wherein said glass material is in an amount of about 10% by weight.

30. The method of claim 23 wherein said glass material is comprised of fiberglass.

31. The method of claim 23 wherein said composite comprises:

said plastic material in an amount between 63% and 67% by weight;

said cellulosic material in an amount between 23% and 27% by weight; and

said glass material in an amount between 6% and 14% by weight.

32. The method of claim 31 wherein said plastic material is comprised of polyethylene.

33. The method of claim 31 wherein said glass material is comprised of fiberglass.

34. A method of manufacturing a component, said method comprising:

providing a composite comprising:

(a) plastic material in an amount between 63% and 67% by weight;

(b) cellulosic material in an amount between 23% and 27% by weight; and

(c) glass material in an amount between 6% and 14% by weight; and

injection molding said composite to form said component.

35. The method of claim 34 wherein said plastic material is comprised of polyethylene.

36. The method of claim 34 wherein said glass material is comprised of fiberglass.

37. The method of claim 34 wherein said component is a spindle.

38. The method of claim 34 wherein said component is a post cap.

39. The method of claim 34 wherein said plastic material is in an amount of about 65% by weight.

40. The method of claim 34 wherein said cellulosic material is in an amount of about 25% by weight.
