1. A method of attaching a composite member to a structure, comprising: forming a laminate of fabric impregnated with resin;applying heat at a first temperature to the impregnated laminate;applying a partial vacuum at a first vacuum pressure to the impregnated laminate to degas the resin and form a degassed, impregnated laminate;positioning the degassed, impregnated laminate on a structure; andcuring the degassed, impregnated laminate on the structure by applying heat at a second temperature and by applying vacuum at a second vacuum pressure, the second vacuum pressure greater than the first vacuum pressure,wherein only a same single vacuum enclosure is used when applying heat at the first temperature, when applying the partial vacuum at the first vacuum pressure, and when curing the degassed, impregnated laminate. 2. A method according to claim 1, wherein the applying heat at a second temperature includes applying heat at the second temperature, which is greater than the first temperature. 3. A method according to claim 1, wherein the vacuum at the second vacuum pressure is a full vacuum. 4. A method according to claim 1, further comprising positioning the impregnated laminate on a heating device. 5. A method according to claim 1, further comprising positioning the single enclosure around the impregnated laminate prior to applying heat at the first temperature. 6. A method according to claim 4, further comprising positioning the single enclosure around the impregnated laminate prior to applying heat at the first temperature. 7. A method of attaching a composite patch to a structure to repair the structure, comprising: forming a laminate of fabric impregnated with resin;shaping the laminate to correspond to an area of a structure needing repair;applying heat at a first temperature to the impregnated laminate;applying a partial vacuum at a first vacuum pressure to the impregnated laminate to degas the resin and form a degassed, impregnated laminate;positioning the degassed, impregnated laminate on the area of the structure needing repair; andcuring the degassed, impregnated laminate on the area needing repair by applying heat at a second temperature and by applying vacuum at a second vacuum pressure, the second vacuum pressure greater than the first vacuum pressure,wherein only a same single vacuum enclosure is used when applying heat at the first temperature, when applying the partial vacuum at the first vacuum pressure, and when curing the degassed, impregnated laminate. 8. A method according to claim 7, wherein the applying heat at a second temperature includes applying heat at the second temperature, which is greater than the first temperature. 9. A method according to claim 7, wherein the vacuum at the second vacuum pressure is a full vacuum. 10. A method according to claim 7, further comprising positioning the impregnated laminate on a heating device. 11. A method according to claim 7, further comprising positioning the single enclosure around the impregnated laminate prior to applying heat at the first temperature. 12. A method according to claim 10, further comprising positioning the single enclosure around the impregnated laminate prior to applying heat at the first temperature. 13. A method according to claim 7, wherein the structure is a vehicle and the curing occurs with the impregnated, degassed laminate positioned on the vehicle. 14. A method of attaching a composite patch to a structure to repair the structure, comprising: forming a laminate of fabric impregnated with resin;shaping the laminate to correspond to an area of a structure needing repair;applying the laminate to the area of the structure needing repair;subsequently to applying the laminate to the area, applying heat at a first temperature to the impregnated laminate and applying a partial vacuum at a first vacuum pressure to the impregnated laminate to degas the resin and form a degassed, impregnated laminate; andcuring the degassed, impregnated laminate on the area needing repair by applying heat at a second temperature and by applying vacuum at a second vacuum pressure, the second vacuum pressure greater than the first vacuum pressure,wherein only a same single vacuum enclosure is used when applying heat at the first temperature, when applying the partial vacuum at the first vacuum pressure, and when curing the degassed, impregnated laminate. 15. A method according to claim 14, wherein the applying heat at a second temperature includes applying heat at the second temperature, which is greater than the first temperature. 16. A method according to claim 14, wherein the vacuum at the second vacuum pressure is a full vacuum. 17. A method according to claim 14, further comprising positioning a heating device adjacent to the impregnated laminate. 18. A method according to claim 14, further comprising positioning the single enclosure around the impregnated laminate prior to applying heat at the first temperature. 19. A method according to claim 17, further comprising positioning the single enclosure around the impregnated laminate prior to applying heat at the first temperature. 20. A method according to claim 14, wherein the structure is a vehicle and the curing occurs with the laminate positioned on the vehicle. 21. The method according to claim 1, further comprising subsequently to applying the partial vacuum at the first vacuum pressure, applying vacuum at the second vacuum pressure greater than the first vacuum pressure to compact the laminate. 22. The method according to claim 7, further comprising subsequently to applying the partial vacuum at the first vacuum pressure, applying vacuum at the second vacuum pressure greater than the first vacuum pressure to compact the laminate. 23. The method according to claim 14, further comprising subsequently to applying the partial vacuum at the first vacuum pressure, applying vacuum at the second vacuum pressure greater than the first vacuum pressure to compact the laminate. 24. A method of attaching a composite member to a structure, comprising: forming a laminate of fabric impregnated with resin;applying heat at a first temperature to the impregnated laminate;applying a partial vacuum at a first vacuum pressure to the impregnated laminate to degas the resin and form a degassed, impregnated laminate;positioning the degassed, impregnated laminate on a structure; andcuring the degassed, impregnated laminate on the structure by applying heat at a second temperature and by applying vacuum at a second vacuum pressure, the second vacuum pressure greater than the first vacuum pressure,wherein the applying of heat at the first temperature, the applying of the partial vacuum at the first vacuum pressure, and the curing of the degassed, impregnated laminate is performed without using two or more vacuum enclosures. 25.
