What material are the black liners used in Aerotech and Cesaroni reloads? I know they are "phenolic," but what type/grade/etc.?
"Plastic" is a very general term applied to many materials. What we commonly refer to as "fiberglass" (cured resin reinforced with glass cloth) is properly FRP - fiberglass reinforced plastic. I was just curious if anyone knew offhand what specific type/grade/whatever the liners are. But, thanks for replying.This is what's on CTI's Motor Data Safety Sheets for 24 - 98 mm:
There articles contain cylinders of ammonium perchlorate composite propellant, encased in inert plastic parts.
The forward closure also contains a few grams of black powder. ProX Rocket motor reload kits are classified
as explosives, and may cause serious injury, including death if used improperly. All explosives are dangerous
and must be handled carefully and used following approved safety procedures under the direction of competent,
experienced personnel in accordance with all applicable federal, state and local laws and regulations. Avoid
inhaling exhaust products.
Cardboard tubes contain various plastic parts. Inside the plastic tube are cylinders of composite propellant
(rocket fuel). The forward closure also contains a small quantity of black powder. All parts are odourless solids.
AT uses both spiral and/or convolute wound paper, and phenolic/paper liners.What material are the black liners used in Aerotech and Cesaroni reloads? I know they are "phenolic," but what type/grade/etc.?
