    Silver steel corrosion plating or replacement

    We have silver steel(BS1407) threaded studs which will have chrome plated nuts placed on them. What is the best corrosion protection for the studs. We are considering nickel plating the studs. Our other option is to replace the studs with a different material.

    Aluminium AL6086-T6 hardness

    The nominal Brinell hardness for Aluminium Al6082-T6 is 95Hb. What is the tolerance on the hardness? Is the there a hardness limit beyond which the material cannot be accepted as Al6082-T6?

    Re: Brittle Cracking of Al6082-T6

    I have an Aluminium part which cracked in a brittle fashion from a hole when an insert was put into the hole. This was done at room temperature and the AL6082-T6 was chromic acid anodised. Can Al 6082-T6 crack in a brittle fashion?

    Thickness effect in compression testing

    I am testing a plastic foam core to verify its properties in uniaxial compression. We think the material we have is too soft. The specification ISO 844 I have to use specifies a thickness of 50mm. The core I can get is only 30mm thick. Will this make a difference? If it does will it be stronger...

    stainless steel identification

    I have attached chemical and hardness specifications for two materials i have named old and new. The hardness was done on 0.5mm thick plates. Why would the chemical analysis be in spec and the hardness be outside spec. Note maximums are given unles a range is given in table below. C...

    Cocuring Decorative laminate

    The company that I work is trying to cocure decorative laminates (thermoplastic cover sheets) onto our thermoset prepreg parts. We would thermoform the laminate first then place it in the mould. Does anyone know if this is feasible and where I can get further information on this subject? The...

    coordinate system inversion

    I have been modelling a surface meshed object in Patran 2005r2. I was rotating the part when I noticed the coordinate system (and the part) suddenly change from a left hand system to a right hand system. Somemore deft movements with the mouse and it inverted back. Why does this happen? I have...

    Diamond coatings for drill bits

    The company I work for requires drill bits to be coated with an ultrahard substance like diamond. The drill bit shape is quite unique so we can make the steel substrate of the drill and send it off to be be coated. Are there any companies out there that would coat these bits?

    Laser guided Prepreg Layups

    We make mainly aircraft seats and various seat components which can have very complex shapes and plies. Our longest lay up instruction (just for prepreg placement) is close to 100 pages. The size of these templates are not an issue it is just the large number and often the customer requires new...

    Laser guided Prepreg Layups

    The company I work is looking to invest in a laser projection system for prepreg layups. We manufacture composite parts for aircraft interiors. Does anyone have any recommendations or experience in these systems and how much they would cost?

    Laminate thickness calculator

    There is a german standard DIN 29971 that might be useful as a first approximation. It assume 0 void content and no resin flow. All the variables can be gotten from the prepreg suppliers. It does not account for the processing parameters. = (prepreg areal mass)*(fibre mass fraction)/(fibre...

    Re: Aluminium 7075-T7351

    Thanks for the post Does the aging temperature change? According to a data sheet on Matweb* there are 2 aging temperatures aging temperature at 107°C (225°F) then followed by 162 °C (325°F) does the aging temperature change? *http://www.matweb.com/search/SpecificMaterialPrint.asp?bassnum=MA7075T73

    Re: Aluminium 7075-T7351

    We are removing Aluminium 7075-T7351 from a part and we need to heat it up to remove it. What is the maximum temperature we can go to without changing the mechanical properties? We only need to spend about five minutes at that temperature.

    MSC Nastran vs MSC Marc

    What is the difference between MSC Marc and MSC Nastran? MSC Marc seems to have more capabilities (with non linear situations) but MSC Nastran is more expensive.
