Compressive strength prediction of CCF300/QY8911 unidirectional fiber reinforced composites

A method for the compressive strength prediction of unidirectional fiber reinforced composite was proposed. Based on the fiber microbuckling mechanism and fiber kinking mechanism, an investigation on the compressive strength prediction of CCF300/QY8911 unidirectional fiber reinforced composites was made. Combining the fiber microbuckling mechanism and fiber kinking mechanism together, which were both responsible for the failure, a combined model for compressive strength prediction of the unidirectional CCF300/QY8911 composite was proposed. According to the compression between the predicted results and measured date, it shows that to compare with the microbuckling model and the kinking model, the combined model makes a better agreement that keep the difference less than 5%.
