Advanced composites have revolutionized design and manufacturing. Today’s composite materials offer exceptional strength-to-weight ratios along with other properties that make them ideal for so many applications. But to get it right, manufacturers need to pay attention to a few critical elements. Fiber orientation and ferocity are two of them.
A composite material is only as good as its ability to perform. Both fiber orientation and porosity affect performance in measurable ways. Therefore, great care needs to be taken in the design stage to ensure a finished product that meets specifications.
Fiber orientation refers to the alignment of the fibers in a glass fiber or carbon fiber composite. This property is considered a mechanical property as it affects the overall performance of a composite. Fiber orientation influences:
In some cases, manufacturing processes have an unavoidable impact on fiber orientation. So everything from flow patterns to layup processes needs to be designed to accommodate the right orientation for the part being produced.
Ultimately, how fibers are aligned in relation to both load and part shape is critical to the part’s strength and stiffness. In turn, strength and stiffness influence part performance.
Ferocity within the advanced composites arena relates to the presence of voids within a composite structure. Ideally, manufacturers want to avoid porosity at all costs. Whether or not it is possible to eliminate voids entirely, manufacturers seek to minimize them as much as possible.
Porosity matters because it impacts:
Material porosity is important enough that quality control processes are designed to minimize it. Manufacturers rely on a variety of technologies and strategies, like vacuum-assisted resin transfer molding, to reduce void content.
Based on what the industry knows about fiber orientation and porosity, manufacturers adopt different strategies to optimize part performance. For example, customizing fiber orientation to match the anticipated load directions is common practice. If a part requires multidirectional layups in order to accommodate complex fiber alignment, investing in those layups is well worth the time and effort.
Some manufacturers rely on computer aided design and simulation tools to determine fiber orientation. In aerospace for example, some of the most complex designs would not be possible without advanced design and simulation tools.
Advanced composites make it possible to build larger passenger aircraft while simultaneously increasing fuel efficiency. They contribute to better designs for military applications, marine applications, and automotive manufacturing. Without them, modern manufacturing wouldn’t be what it is.
Manufacturing advanced composites is a science. It is a science that pays a lot of attention to the details, like fiber orientation and porosity. Getting it right means producing strong, durable, and reliable materials modern manufacturing relies on.
