Please I need a full solution to this Composite Materials problem
A non-engineer DIY youtuber is trying to prove that aramid fibre composites are effectively 'unbreakable' (think Captain America Vibranium shield unbreakable), despite the comments of his engineer followers assuring them that this is not the case. The youtuber's plan is to replicate a lay-up they have found online and build it themselves [45,-45,90,0]s. They will make a small flat composite plate and they will suspend themselves from it to show that it can carry their weight (95 kg) without any problems. Using this information and some characteristic values of composite constituents the engineer subscribers of the youtuber do a quick analysis using the Netting and 10% rule to prove that this will not work. Using the information provided and assuming that the resulting composite will have 90% (best case scenario) of its estimated strength due to problems caused from the manufacturing process. Aramid Fibre tensile strength 3620 MP Epoxy Matrix tensile strength 65 MPa Volume fraction of matrix 0.4 Ply thickness 0.150 Table: Typical properties of the materials used. mm I. What is the tensile strength of a composite lamina that is made of the constituents given?) II. What will be the load intensity applied on the composites x direction from the suspension of the youtuber? III. What will the actual applied stress on the composite on its x direction be? IV. What will the tensile strength of the lay-up be according to the netting and 10% rule? V. Will the composite hold the youtuber's weight or the whole endeavour will end up being a viral fails clip? Under what circumstances would this demonstration' work? (Justify your answer).
