MANUFACTURING Specimen Manufacturing
Intec's specimens manufacturing department provides turn-key specimen fabrication. From panel fabrication through bonding, tabbing, machining and assembly, Intec provides the full spectrum of elements and specimens to test. The entire process can be FAA DAR witnessed so that specimens can be certified for use in allowables and qualification testing.
Test Panel Fabrication
Starting from raw materials (prepregs, cores, dry fabrics, resins, adhesives), our quality system tracks material, time, and shelf life, and assures ply orientation and location. Panel IDs are carried through the process cycle (autoclave, vacuum oven, press, RTM, out-of-oven cure, ambient cure). Intec's process equipment meets the rigorous aerospace requirements for process control, monitoring and reporting. (Standard processes up to 850 °F and 300 PSI.)
Tabbing
Whether Intec-manufactured or customer-supplied, test panels are generally tabbed as a group from a subpanel cut from the larger test panel. Film or paste adhesive is used to bond the tabs (doublers) onto the subpanel, using autoclave or press processes. The subpanel is then ready for specimen machining.
Specimen Machining
Intec has invested heavily in research and equipment to advance the science of specimen machining. Machining starts with the layout of specimen groups on the actual test panel. Diverging colored lines and photographs are used to document and track each specimen's location in the panel. Wet diamond cutters are use to slice or mill specimens into the desired shape, leaving high quality perpendicular edges (better than 10 rms). Holes are usually cut on backed specimens using drill point reamers, resulting in exceptional hole quality.
Calibrated digital measurement equipment is used to assure specimen conformity and to document dimensions required for test input.
