Weight: Fiberglass is heavier than carbon fiber, which can be a disadvantage in applications where weight is a critical factor. In aerospace engineering, the choice between carbon fiber vs. fiberglass is an often-debated topic among engineers, designers, and enthusiasts alike. Both materials have been widely used across various industries, from automotive to aerospace, sporting goods to marine. Weight: Carbon fiber is roughly a third lighter than fiberglass. This strength comes from its high tensile strength and low density, making it ideal for applications requiring both. In my opinion the big difference is carbons are $500 more,scratch easy, and are more prone to breaking. Haven't tried composite I just say the hype for carbons isn't worth it if you're not strictly competitively freediving.
