In the world of composite manufacturing, the term "prepreg tack" often surfaces as a pivotal factor dictating the success of automated processes like Automated Fiber Placement (AFP) and Automated Tape Laying (ATL). This seemingly obscure term holds immense significance in the realm of carbon fiber reinforced plastics, which are crucial for lightweight construction in modern aviation and beyond. This blog delves into the intricate world of prepreg tack, guided by insights from a comprehensive research article titled "A Review of Mechanisms, Measurement, and Manufacturing Implication." The Essence of Prepreg Tack: At its core, prepreg tack refers to the stickiness of prepreg materials—pre-impregnated with resin fibers—that facilitates their placement and adhesion during automated lay-up processes without intervening in the curing stage of epoxy. This property is not just about being sticky; it embodies a complex interplay of adhesive and cohesive forces influenced by a myriad of factors, including environmental conditions, machine parameters, and intrinsic material properties. Understanding and optimizing prepreg tack is thus a dance with physics, chemistry, and engineering. Read more: addcomposites.com/...
