Needs Change, Materials Change, Composites Grow

Composite use continues to grow in the aerospace field.  My recent article in Aerospace Manufacturing and Design  discusses some of the benefits and challenges with the use of composites and notes that simulation will continue to play a critical role in the growth and acceptance of composites in aerospace as well as other industries.  Here’s a preview of what you’ll read in AM&D:


Composites, of course, weigh considerably less than conventional aluminum and titanium materials, and they offer a number of other benefits as well.

Carbon fiber reinforced plastic (CFRP) is inherently very stiff; therefore, when it is used to build a fuselage, the aircraft’s core structure is stiffer than with other materials. As a result, cabin pressure can be at a higher level when flying, more closely approximating air pressure near the ground. With higher pressure in the cabin, studies show that passengers experience less fatigue while flying, and there will be less ear popping when landing. In addition, windows can be larger with a stiffer fuselage, so passengers will not have to duck down to see out the window.

Altair continues to develop expertise and innovative software to address the design, analysis, and optimization of composite structures, so check back for more thoughts on the subject as we continue the conversation.
