Maybe try dacron or nylon sail repair tape. Typically comes in 2, 3, 4" width. It sticks well and is strong. Available in marine supply houses. Comes in colors. Comes in clear also. Dacron repair tape is said to be stronger than nylon, but either is very strong.
Were I going to use it I would start by sealing an approx. 3" long piece 90 degrees at each end of the rip. Maybe one in the middle too. That should give strength where the tear may want to pull/run. Follow with lengthwise piece(s) (overlapped if necessary). Stitch the tape down and set the glue by rubbing with a spoon or rounded screwdriver handle end against a hard surface.
Cut any corners with a radius. Square corners tend to lift easier.
Normally I would recommend taping both sides for strength. For the awning I would just tape the top and keep an eye on it for signs of posible failure. Taping just the top should make the underside look more OEM unless the tape really matches the awning color closely.
Good luck. vic
