I just finished my Ph.D. in mech engineering with an emphasis on composite design. Believe it or not I got paid to make carbon fiber and glass fiber race car/boat/airplane parts for the 5 years of grad school. Not much money, but school was free. I feel like the kid that got to play in the sandbox while everybody else hit the books:-)
I'm really into the vacuum infusion method of making parts, as this produces a relatively cheap part without voids in the matrix.
Funny thing... I was expressly forbade from ever making a kevlar part in graduate school. Something about poor adhesion to the matrix, poor compressive properties, water absorption, etc. I haven't really looked into it much myself. Can you tell me the virtues of a Kevlar composite? I'd like to hear a different perspective.
