Effect of graphite orientation distribution on thermal

2021/1/1Graphite has the negative value of CTE so that the CTE of composite could be reduced while Cu matrix is reinforced by graphite. Therefore, a CTE of composite which is much smaller than the CTE of Cu (17.5 10 −6 K −1 ) could be obtained by preparing graphite/Cu composite.

Graphite film/aluminum laminate composites with

2016/1/15For graphite film/aluminum laminate composites, it is very easy to control the orientation and distribution of the graphite films by controlling the stacking of graphite films and metal foils. Therefore, it is easier to bring the enhancement effect of the graphite films into full play than other kind of reinforcements such as graphite flakes and CFs. 3).

Pre

Pre-preg is a composite material made from pre-impregnated fibers and a partially cured polymer matrix, such as epoxy or phenolic resin, or even thermoplastic mixed with liquid rubbers or resins. The fibers often take the form of a weave and the matrix is used to bond them together and to other components during manufacture.
