Most literature I've read states that debulking is necessary for prepregs, as it helps remove the air trapped by the resin between the plies. I'm just not sure whether this would be necessary for a dry stack of...

    Apologies if I'm asking such a stupid question but can anyone here tell me the formula to calculate the loading on 3 supports of a beam when there is unequal spacing between them and the beam has a single offset point load? The point load is 1020kg offset 950mm from the left. Support 1 is at...
