Sentence examples for composites are difficult from inspiring English sources

Carbon fiber reinforced polymer (CFRP) composites are difficult to cut materials due to their anisotropic structure and extremely abrasive nature of the carbon fibers.

However, the high temperature mechanical behaviors of these composites are difficult to be investigated because it is hard to measure these structural changes in the mechanical test.

Layered composites are "difficult-to-machine" materials as it is inhomogeneous due to the matrix properties, fibre orientation, and relative volume fraction of matrix.
