Acrylic Canopy / Windows Bolted Joint
Acrylic Canopy / Windows Bolted Joint
(OP)
I am looking for information on bolting an acrylic canopy or window to an airframe. I have seen the edges of the acrylic windows wrapped with fiberglass to provide bearing strength and elastomer bushings used. The end goal is a bushing/material combo (and process) that will provide a published bearing capability without extensive testing. Are there any published processes and analysis methods?

otherwise, using an NAS spacer would protect the plastic from clamp-up stresses.

Use an NAS aluminum spacer with a medium-to-hard rubber tube-sleeve around the OD of the spacer.
Spacer prevents crushing, rubber prevents direct contact between hole and metal spacer... and allows some degree of expansion/contraction.
Drilling acrylic is tricky! Special drill-bit geometry is required for decent holes.
