AI Thread Summary
Automobile glass must have high impact resistance, with laminated glass used for windshields and toughened glass for side windows. Compressive and tensile strengths are important, but shatter resistance is crucial for safety, especially in emergencies. Acrylic materials are generally avoided due to their susceptibility to UV damage, which can impair visibility, and their inability to shatter safely in submerged situations. Some suppliers claim to offer UV-resistant acrylic with warranties, but concerns about cost and performance remain. Overall, glass remains the preferred choice for automotive applications due to its safety and durability.

I just wanted to understand what are the main properties required for an automobile glass. I understand that for a windshield of an automobile, the material must have high impact resistance but do compressive and tensile strengths also matter that much?
For the window glasses in automobiles what properties are required?

I have generally observed that the windshield is made of laminated glass and the other glasses are generally toughened glasses.

why acrylic material sheets not used commonly in place of these glasses?

The issue with acrylic is that it tends to be susceptible to UV damage that would cloud the users vision. Have you ever seen a car with old, yellowed headlights? It's the same thing.
Acrylic can't be used for the side windows either because the side windows need to be shatter-able in case the vehicle becomes submerged.

Aside from that... I'm not too sure.
 
but i have seen a few suppliers of acrylic saying that their material doesn't yellow when exposed to sunlight and UV rays and some even give a warranty of 10 years.

i agree that the cars side glasses must me shatter-able so as to break open during emergency, but i suppose for other type of applications say in construction equipment they might be used. But i am not sure is acrylic costly compared to glass?
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below.

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
