With the experience in composite parts manufacturing, EFW in the early s started with its own development of new sandwich panel and laminate part lay ups, materials, semi finished products as well as the sophistication of existing and implementation of new manufacturing technologies.

Sandwich panels are an important composite structure in aerospace applications as well as in high performance automobiles, boats and wind turbinesTypically a sandwich panel is comprised of a low stiffness, low density inner core enclosed by two stiff outer skins, as shown in Figure , where the whole assembly is held together by some sort of

But it is hugeThousands of pounds of advanced composites materials, including thermoset prepregs, honeycomb core and advanced engineering thermoplastics, are used in each aircraft according to one source, more than , lb , kg for a single Boeing .
