I've been asked to reverse engineer an obsolete valve for a one-off application. I've attached pictures of the cross-section of the original valve to illustrate the configuration. I am worried about not being able to achieve leak-tightness due to the metal to metal seating. Please help point...
The ASME B&PV Code Section III, Division 1, Subsection NF (supports) provides a material exemption in NF-1110(e) for:
"compression dynamic stops used as stops for seismic and other dynamic loads that are designed primarily for compressive loading and are not connected to the support or pressure...
in the previous post, i included an example of a blade with large bundles. here is an example of one using smaller bundles.http://files.engineering.com/getfile.aspx?folder=86c68b0c-88c6-4c97-b129-fe1a322a5e0b&file=easton_blade.jpg
"Larger bundles carry larger loads per bundle but have proportionately less surface area to transfer to other bundles. So shear stresses between resin and fiber bundles increases."
are you saying that larger bundles ('checkerboard' as i called it) will delaminate easier compared to smaller...
I am specifically interested in carbon fiber re-inforced composites. Generally I see relatively finely woven patterns. However, in some materials i have seen a larger weave, more resembling a checkerboard, where there is less weaving of the fibers per length. I understand the finer weaving is...
