Fiber-reinforced thermosetting composites are of great significance in aerospace,marine,automotive,wind power,and civil engineering fields.They have outstanding advantages and can reduce weight and enhance performance,especially by replacing steel pieces.However,nonreversible cured deformation is an obstacle to the rapid development of these composite components.Studies in this field typically focus on the numerical prediction of the effects of cured deformation on composite components,which helps engineers design and modify the mold to compensate for deformation.In this review we discuss the latest achievements relating to cured deformation mechanisms,prediction models,and control strategies in fiber-reinforced material fields.In particular,different intrinsic and extrinsic factors that affect cured deformation are summarized and five main control strategies are proposed:die surface compensation,process optimization,structural optimization,tool-part contact optimization,and development of other methods.In addition,the effects of these factors on controlling deformation are compared.Unlike previous studies,this study integrates control strategies and the main mechanisms involved to achieve a more comprehensive view of cured deformation in thermosetting composites.
