Reinforcement pullout strength

As briefly noted in Section 41.1.4, PLCs provide mechanical strength without the problems of easy separation of the reinforcement from the flexible matrix (fiber pullout)... 

Flax fibers have recently been investigated as reinforcement in polymeric foam matrices for current components used in the transportation industry (Fuqua et al. 2010). Despite the fact that plywood bus floorboards are chemically treated to prevent decay, they stUl require repeated replacement over the lifecycle of a transit vehicle (Vaidya et al. 2004). Mechanical testing of both flexural performance and fastener pullout capabilities of flax-fiber/soy-based PU foam composites demonstrated that they could serve as a suitable flooring replacement in mass transit vehicles. Stmctures ranging from 55% to 70% renewable material by weight with an inexpensive lower quality flax mat (i.e., 40% shive content and 60% fiber) could produce flexural strength comparable to pl3rwood with little environmental impact (Fuqua et al. 2010). 

A most important additional requirement for the reinforcement function is that the geotextUe is made to have a good bonding strength, T, with the soil, so as to resist slippage of the soil over fabric surface or the pullout of the fabric from the soil. Evidently in order to ensure effective...
