In order to obtain the inter-yarn friction coefficient in aramid fibers, a new methodology is developed. Experimental yarn pull-out test and 3D numerical model have perfomed in Kevlar (R) 129 (K129) aramid. An optimization of classic numerical models in order to simulate pull-out tests and obtain the inter-yarn friction is carried out. Numerical simulation results were compared to experimental yarn pull-out curves and based on linear dependence of the pull-out load with the friction coefficient, the inter-yarn friction coefficient of K129 aramid has been obtained.
