And also we have no technicians in our uni..No machines..All we do is on our own with our own hands. So i need to decide if it is manufacturable and then manufacture it. I live in Oman..where we are still way back in terms of technology :( And yes accuracy and tolerances will be a problem in...
Hi Thanks for your reply! We already competed once with an aluminum chassis, but it was a little heavy.(mainly 100x40x2mm rectangular hollow sections). Though it could be made lighter no doubt. The reason i wanted to go for the composite chassis is because we already have all the materials...
Actually We have no test lab and no such test equipment. But the loadings and stresses in Shell Eco Marathon, where top speeds are about 40km/h max. I beleive it is not as complex as the FSAE designs.. Normally static loads are about 500-700N at each wheel suspension point. Also for the side...
I modelled the plies and core seperately, it can be easily done in ANSYS Acp. We currently have a complete sheet i.e. (48"x96") of 30mm thick Nomex and a little shorter of 9mm thick Nomex..density 48kg/m3. Yeah this kind of 2x2 twill weave is normally used for cosmetic purposes. But we have...
Hi Guys! I am new here. I am currently doing my bachelor thesis on the Shell Eco marathon prototype car. I am thinking of making the chassis this time with carbon fibre+nomex sandwich pannels. So the carbon fibre we already have in stock is 3K 2x2 twill 200gsm carbon fabric. I am using Ansys...
