In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

open access: yesJournal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Fatigue behaviour of a C/C-composite under interlaminar shear loading conditions

open access: yes, 2022
The fatigue behaviour of a carbon fibre reinforced carbon under interlaminar shear loading conditions was investigated at room temperature. Two different testing procedures were applied: the conventional short-beam-bending test and a new compression ...

Investigating Crack Resistance Behavior of Polypropylene Using J integral, J‐R Curve and Fractographic Analysis

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...

Quantifying Fiber Bridging in Mode I Fatigue Delamination of CFRP/GFRP Hybrid Laminates Using a Superposed Traction–Separation Model

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Hybrid CFRP/GFRP laminates offer an attractive balance between mechanical performance, damage tolerance, and cost efficiency. However, fiber bridging during mode I delamination increases crack‐growth resistance while masking the intrinsic fatigue behavior of the material. This study applies a traction–separation‐based superposition approach to
