@WKTaylor Great information thanks @sparweb Yes, certification aspects are covered stand alone air conditioning and ventilation requirements is another issue we are trying to address, we know how to hook up with aircraft system, but since there is a requirement that it need to be removed in 30...

Hello, We may get a program on developing main deck ULD, for crew bunks and not storage. Customer wants it to be handled (fork lift), sustain abuse and extreme conditions of tarmac, but main purpose is to be utilized as crew bunk during non-ttl operations. I was wondering what is main material...

Sorry for vaguness in my post. One part (cureved panle) has embedded metal in composite panel, for which we have helicoils. Mating part is also composit part with thru inserts in them. The hole alignments happens two flat sides of curved panel. I will take the recommendations and look thru how...

Hello, I am not sure if there is such thing, but we are facing issues aling parts at final assy, one part comes with helicoil preinstalled in them and other part with thru hole, alignining these is a nightmare. I was wondering if there is solution to have floated helicoil or nut inset? We can...

@edstainless Any lead on consultants?

@geesaman.d We are working with existing manufacturing company there. We will be giving them component level to final assembly manufacturing work, we are paying for labor only and we will be repsonsible for materials. This involves machined parts, composite manufacturing and sub/ final assembly.

Hello, We are US based mid-scale interior manufacturing company and looking for options to outsource manufacturing to Mexico. I was wondering, if there are any research papers/ case studies that can help us plan better this activity, if someone has direct experience that will helpful as well...

Yes, it is for aircraft interior products

WKTaylor Great info, we had very similar experience in how we prepare lap shear coupons and any incosistencies results in high variation in results. However, I don't understand why would FLAM/ fire properties test need to be done as well. I assume lap shear alone satisfy needs of potential...

So basically chemical properties might alter during shipping and also supplier may have issues. Thanks you!

I agree with what you are saying, however I want to understand logic behind these receiving insection test requirements

Hello, We use number of OEM adhesives for Aicraft Interior Applications, they come with receiving insection testing requirements such as lap shear & flamability. These are batch tested by the supplier, so wondering why there are requirements to test again after you receive them? Is there a risk...

Compositepro: Hate to do it here, but couldn't find your contact information, do you do consulting ?

I am working with panel layup where we have Thermoplastic, nomex core and aluminum parts. Due to CTE differences, thermoplastic doesn't adhere well with aluminum, what are the recommended finishes on embedded aluminum ?

Yes, I am reading that material as we speak, I actually have handbook from them, but it doesn't go in to details of the what cure cycles work best for this material. My original question is what are the recommended books/ research in this area, I do like to read :) Thanks for the response anyways.

Some additional information: Thermoplastic skin we are planning to use comes in RTL solid laminate it has CTE of 3.1/F Adhesive we are using is fabric type with activation temp around 270F We are making curved panels about 0.50-0.75" thick and like you said I am trying to come up with...

Steel has CTE 8-12 and max service temp of 1000 F, so material wise it should be fine.

We are making curved panel with thermoplastic face sheet + Nomex core + thermoplastic face sheet lay up in a tool and then using oven, I was wondering is it a better practice to preform the facesheet to required curvature prior to putting in tool ? Also where can I find guidance/ reading...

Hi, I am doing some long beam coupon test using composite panel with build up: Nomex core and phenolic glass fabric skin, purpose of this test is to do qualification of panel process. ASTM D5467 lists out acceptable/ unacceptable failure modes, but coupons which I am testing fails in dis-bond...
