introduction： Stiffening rib Ideal design In order to overcome the problems that may be caused by the large wall thickness，Use is an effective way to reduce wall thickness and increase rigidity。 Generally speaking，The rigidity of the component can be enhanced in the following ways §Increase wall thickness； §Increase the elastic modulus（Such as increasing the content of reinforced fiber）； §Design considerations。 If the material used in the design does not meet the required rigidity，Materials with greater elastic modulus should be selected。The simple way is to increase the content of reinforcement fibers in the plastic。however，Zaat
