Abstract
Within this paper, behaviour simulations of various polymer matrix composite laminates subjected to three and four-point
bending using the finite element method have been carried out. The models have been designed and analyzed with MSC
Patran and MSC Nastran. Four types of composite laminates have been developed based especially on epoxy resin
reinforced with Chopped Strand Mats of various specific weights and RT800 glass fabrics, namely four layers 4 x CSM450,
four layers 4 x RT800-warp, four layers 4 x RT800-weft, eight layers 2 x CSM600/4 x RT800-warp/2 x CSM450 and eight
layers 2 x CSM600/4 x RT800-weft/2 x CSM450 composite laminates. Using the finite element method, strain distributions
of these four laminates subjected to three and four-point bending have been determined. The theoretical approach has
been compared with experimental data obtained on LR5KPlus Lloyd Instruments materials testing machine. The
comparison shows close values between both approaches..
