This entry was posted in Trends. Nevertheless, opportunities do exist to lower the cost of utilizing them. In addition, DoD-funded research could be focused on standardization of procurement specifications.

Areas in which current analysis methods are weak, and where historical data would be beneficial, include compression after impact both solid laminate and sandwich structuremechanically fastened joints, delamination growth, and fatigue.

Although prices for carbon fiber from SAF- and textile-based precursors prices have dropped to an all-time low, current PAN-based processes are unlikely to allow further cost reduction. Thus, one would not expect downward changes in the prices of these materials.

The same phenomenon is responsible for their relatively low compressive properties.

Applications such as brakes and electronics could create high-volume markets that can be satisfied only by pitch-based carbon fibers. Suppliers of the small-tow carbon fiber 3k to 12k filaments are working to reduce their costs while maintaining fiber properties.

Increases in electrical conductivity of as much as eight orders of magnitude at 1 weight percent of filler have been observed. Hoboken, New Jersey, Investment should be made in fundamental studies that couple online monitoring of the development of molecular orientation during flow, solidification, and heat treatment to the verification of fundamental process and product models that incorporate molecular detail.

Each block consists of testing and analysis that increase in complexity with each successive block and builds on knowledge gained in previous blocks. Composite material procurement specifications represent one area in which unneeded testing may be imposed. Detailed analysis and profiles of additional market players.

The process is largely a manual process lacking quality control and automation.

Suppliers of the small-tow carbon fiber 3k to 12k filaments are working to reduce their costs while maintaining fiber properties. Work is already going on in pitch-based fibers 17 and PAN precursors. First, does a wider distribution of properties such as strength, for example, affect the realizable properties of the final part and, if it does, can this effect be predicted reliably and accommodated in the final composite design?

The failure occurred inside the graphite fiber composite instead of in the adhesive. Currently, there are rigorous statistical methods for selecting the numbers of specimens tested at the lowest building block level coupon testing to obtain material property basis values.

Interfaces 3 8 This success was observed at a loading of 5 weight percent MWNT. This molecular ordering or lack thereof ultimately determines the mechanical properties of high-performance fibers.

When assembly of subcomponents is necessary, good fit without the need for rework or additional operations is essential. However, for this market to grow, the price of high-thermal-conductivity pitch-based carbon fibers must be reduced significantly.

Investment in programs developing new nanostructured micron-scale fibers with nanoscale structure and nanoscale-diameter fibers is critical to fibers exhibiting a step change in properties.
