That model looks better. In my experience, the "bubbles" occur when the surfaces are not fair.

Helps if I attach somethinghttp://files.engineering.com/getfile.aspx?folder=b8ef3282-74cd-47c2-9b9a-02982e0cc255&file=imported-model_11-16-09_half_with_chamfer_step_file.zip

There is a lot of discontinuity in the surfaces of the original model. How about this method to get 1/2 half?

I see in the model that there is a tiny fillet or chamfer, I did not look closely enough to tell which, in the original model. I think you need to get rid of that and then you will be able to do it. Another method might be to draft from an edge but I am not sure how far you want to go up the seam.

Which edge do you want to be chamfered? Have you posted this question on the Solid Edge bulletin board?http://files.engineering.com/getfile.aspx?folder=32f77c1d-daf6-4618-9b54-c48aeb8fbe5a&file=chamfer_location.jpg

Have you tried any of the Lantor products? We have had success on infused parts using Lantor Finishmat against the gelcooat, then a layer of continuous strand mat then a layer of Lantor Soric TF followed by the structural laminate. All those plies go onto the mold in a dry state.

Look in CE 12215-5. They have a method for calculating strength and stiffness for a given volume fraction. It is not exact, but it is very close.

Why not use ExpresRoute?

Does anyone have a formula for calculating a ply thickness for a fabric if you know the resin fraction, the fiber density, and how much pressure is used for the lamination (open mold, vacuum bag, autoclave)? If you could share it with me then that would be appreciated. Regards, Peter Smith

Does anyone know of any good, (hopefully one part) adhesive to bond a stainless steel bracket to a piece of stainless steel sheet metal? Needs to be applied on a vertical wall at room temperature but still adhere at 30 degrees F. Wants to be able to have a shear strength of about 100 psi...

Weld a thick wall tube into the flagpole for the pin(s) to bear against. You can then also weld a doubler onto the outside of the flagpole to locally reinforce the wall.

We are a yacht builder that uses Solid Edge. We build nine different powerboat models and seven different sailboat models, and we have an MRP system. We are trying to devise a way to tie the drawings to the MRP but still keep the drawings esy to identify when we search using Windows Explorer...

We are in the process of creating a standard file name or numbering system for our Engineering department. Is there a numbering or naming standard that is simple to use and robust? Is one preferred over the other? We build yachts so we have drawings ranging from laminate schedules to carpentry...

Steve, We are presently using an Excel spreadsheet to handle strength and stiffness criteria, but am interested in skin buckling and core shear problems. I am especially interested in core shear when the core is thick and the skins get thin. Any help you can give as to what types of programs...

I am looking for software to analyze strength and stiffness of cored composite laminates that are subjected to uniform loads. Typical laminates are Kevlar/E-glass on one face, a core made from Balsa, or PVC, or SAN, and then Carbon on the inner skin. Does any know of a robust software package to...
