I am looking for a supplier for airbus specification DAN 1216-01 material. It is a chop strand glass fiber reinforced phenolic material used typically in aircraft interiors.
Does anyone know of a supplier who stocks this material?
I am using MSC.FEA 2008 R1. Its basically a patran bundled with nastran. The default unit is always inches. Is there anyway of changing the default unit to meters?

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.
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?
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?
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...
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.

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...
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?
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?
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.
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.
The company I work for in South Africa is trying to decide on package to model complicated composite structures. In my country reasonable support can only be obtained for Ansys and MSC Nastran so these are the only packages considered. We are faced with Ansys Workbench and MSC Nastran and...
