Abstract

AbstractCuring high‐performance carbon fiber reinforced polymer (CFRP) structures with economical and energy‐efficient off‐oven techniques is important for the widespread application of the composite. In this work, we reported a magnetic particle‐induced in situ heating method to controllably cure CFRP laminates with stacking sequences of [0]8, [0/90]4s and [0/45/90/−45]2s. Results showed that all the laminates can undergo a consistent, layup‐independent two‐staged heating protocol via regulating the magnetic field intensity. Under the same curing protocol, the three stacking‐sequenced CFRP laminates can be cured more completely under induction heating than oven heating, in addition to a moderately improved tensile and flexural properties. However, the porosity of the laminates slightly increased under induction heating. The proposed new curing method provides a new avenue to the fabrication of advanced CFRP composite structures without oven or autoclave.Highlights A particle‐induced in situ heating method to controllably cure carbon fiber reinforced polymer (CFRP) laminates was proposed. This method was capable to cure CFRP laminates with different stacking sequences. Mechanical property of laminates was moderately improved under this method.
