Tell us what you actually want then we can stop playing 20 guesses.

Can we have a clue as to the environment of use, hot, cold, humid, chemicals, food contact, etc etc.

Chris. I am not convinced that there are glass fibres available that are suitable o reinforce a clear plastic that also have a similar RI. I would be very interested to find such a thing if it does exist.

My Trend Micro Antivirus software blocked your site as dangerous.
Can you post pics on a safe site.
Without doing sums, I expect an amorphous grade of PET should do it.

The design you now show requires exceptional tensile and flex mod as well as good impact.
Frankly that design is not really suited to plastics, especially the threaded part.

Pat, do you believe it's possible to add fibers w/ the same RI as a high quality grade of PMMA to negate the bending but still remain clear, as demon said?
RE: transparent plastic with high yield
To successfully reinforce plastics several things need to happen
1) The matrix resin has to wet the fibre.
2) The matrix resin has to bond to the fibre.
3) The interface between the matrix resin and the glass must be durable in the environment of use.
4) The glass fibre needs to be strong and to have a high aspect ratio to be an effective reinforcment.
To obtain all four, coatings are normally used, so it requires a combination of a glass that can be drawn to a very fine fibre, is strong, will accept the correct coatings, is clear and has the same RI as the plastic and the same deal for the coating and all three components need to be durable in the application.
To begin an investigation would require a sizable market to justify commercially. I will make some inquiries. They might also involve Chris.
I doubt acrylic can be made to withstand more shock loading by the addition of glass.
Just how clear do you need this re discoloration and re haze and refraction as these will make a big difference.
Can you indicate the size of the market in tonnes per year.
Can you identify at least what continent or region you are in.
