dependent mechanical properties of the composites. Isotropic composites with uniform fibre content distribution through the specimen thickness were also prepared for comparison with the spatially-graded composite. When the face of a sample with high glass
fibre content was loaded, the ¯exural strength and the impact energy of the composite showed improved values by comparison with
those of the isotropic composite. On the other hand, poor ¯exural strength and impact energy were observed when the face of the
sample with low fibre content was loaded. Finite-element analysis was performed to investigate the stress/strain distribution of the
deformed model structure with the variation of moduli through the thickness. Despite having the same fibre content, the glass-fibre-
mat/PP composites could have the characteristic mechanical properties with different spatial distributions of fibre content.
