Thanks for the replies guys, really appreciate it. I was actually a little worried about delam but forgot about CTE. I think this will be a no go for me; there are too many uncertainties involved. I'm going to have to look at an alternative solution. @Compositespro, quick question with regards...

Hi guys, i have an application where i am bolting a structure to a CF laminate. I need to use a plate (drilled & tapped); embedded fasteners won't work for my application. I have other features moulded on the rear face, so ideally i would rather not mount the plate on that face. Are there any...

Thanks for the replies, you've answered my question. Is there a way to improve the consolidation of the dry fibres and prevent wrinkling or voids? I will essentially have a sandwich construction of dry fibre laminate at the bottom, followed by a think foam filler (closed cell), and then another...

Is it necessary to debulk a dry stack of carbon fiber plies prior to resin infusion? 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...

Yes that's the one.

I'm transferring my company's pipes & fittings speadsheet over to 2016 and was wondering what the current opinions are of it. The code seems to be a significant overhaul from previous versions. I've worked with BS4994 & BS7159 and they seem easier to digest. What's the general thoughts on the...

The formula was correct but I had duplicated d1, d2, & d3. The wrong input was then being referenced for the main formula. So basically, instead of using the height of each rectangle, the centroid was used.

I have it all working ok now. It might not look elegant, but I'm confident that they're right as they match the cad section properties. I thought I'd upload the results in case someone else may be looking for something similar. I've also included the results based on the Y-axis. Thanks for all...

Thanks hokie66. I've got it working now. I was doing this late last night and completely overlooked the basic stuff . I thought it was the formula itself that I had wrong.

Hi Everyone, I'm trying to calculate the deflection of a beam but I'm not 100% sure about my calculation of the second moment area. I've compared it to the section properties in a cad model and they don't seem to add up. I'd be grateful if someone could have a quick look over my formula and...

Sorry for the late reply, but thanks for all the help guys. Its much appreciated.

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...
