CLAIMS

1. A composite laminate structure comprising:

a core of non-woven thermoplastic/fiberglass mix matte;

a top layer located on one side of said core, said top layer including uni-directional structural tape of woven glass/thermoplastic composites; and

a bottom layer, on a side of said core opposite said top layer, said bottom layer including uni-directional structural tape of woven glass/thermoplastic composites, said top and bottom layers are sealed to said core.

2. The composite laminate structure of claim 1 wherein said top and bottom layers include continuous 0°- 90° fiberglass reinforced thermoplastic.

3. The composite laminate structure of claim 2 wherein the core includes a needle punched matte.

4. The composite laminate structure of claim 2 wherein the core includes a thermally treated matte.

5. The composite laminate structure of claim 2 wherein the core has an area weight of 100 to 2500 g/m2 and a thickness from 0.5 to 6 mm.

6. The composite laminate structure of claim 2 wherein the top and bottom layers are heat-fused to the non-woven thermoplastic/fiberglass mix matte.

7. The composite laminate structure of claim 2 wherein the core includes thermoplastic and reinforcing fibers supplied in the form of multi-fiber strands.

8. The composite laminate structure of claim 7 wherein multi-fiber strands are carded so that, there are few unopened and partially opened strands and the matte has a homogenous appearance.

9. The composite laminate structure of claim 8 wherein the carded matte has a lofty appearance prior to sealing with said top and bottom layers.

10. The composite laminate structure of claim 1 wherein said top and bottom layers uni directional continuous composites are oriented perpendicular to one another.

11. A method of manufacturing a composite laminate structure including the steps of:

providing a core of non-woven thermoplastic/fiberglass mix matte;

providing a top layer said top layer including continuous 0°- 90° fiberglass reinforced thermoplastic;

locating said top layer on one side of said core;

providing a bottom layer, said bottom layer including continuous 0°- 90° fiberglass reinforced thermoplastic;

locating said bottom layer on a side of said core opposite said top layer; and

sealing said top and bottom layers to said core.

12. The method of manufacturing a composite laminate structure as set forth in claim 11 wherein said top layer includes uni-directional structural tape of woven glass/thermoplastic composites.

13. The method of manufacturing a composite laminate structure as set forth in claim 12 wherein said bottom layer includes uni-directional structural tape of woven glass/thermoplastic composites.

14. The method of manufacturing a composite laminate structure as set forth in claim 13 including the step of needle punching said core prior to sealing to said top and bottom layers.

15 The method of manufacturing a composite laminate structure as set forth in claim 13 including the step of thermally treating said matte prior to sealing to said top and bottom layers.

16. The method of manufacturing a composite laminate structure as set forth in claim 13 wherein the core has an area weight of 100 to 2500 g/m2 and a thickness from 0.5 to 6 mm.

17. The method of manufacturing a composite laminate structure as set forth in claim 13 including the step of heat fusing said top and bottom layers to said non-woven thermoplastic/fiberglass mix matte.

18. The method of manufacturing a composite laminate structure as set forth in claim 13 including the steps of supplying thermoplastic and reinforcing fibers in the form of multi-fiber strands, blending the multi-fiber strands in an air stream, and depositing the multi-fiber strands on a moving belt,

19. The method of manufacturing a composite laminate structure as set forth in claim 13 including the steps of carding multi-fiber strands to reduce unopened and partially opened strands and providing the matte in a homogenous appearance.

20. The method of manufacturing a composite laminate structure as set forth in claim 13 including the step of orienting said uni-directional fiberglass reinforced thermoplastic in said top and bottom layers perpendicular to one another.
