Curved-Line Cutting Using a Flexible Circular Saw

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
We propose a flexible circular saw for high-speed cutting of curved lines in carbon fiber-reinforced plastic (CFRP). A conventional circular saw is appropriate for straight line cutting, but it cannot be applied to curved line cutting because of the ...

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

Polymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Performance evaluation of thick carbon fiber‐reinforced laminates manufactured using six‐magnetron microwave system

Polymer International, EarlyView.
IM7/Cycom 5320‐1 unidirectional prepreg has been used to fabricate 64‐layer laminated composites. A custom‐built six‐magnetron microwave applicator and an autoclave were employed to manufacture the composite panels. Mechanical performance of the microwave‐cured composites has been juxtaposed to autoclave‐cured composites in terms of uniaxial tensile ...

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

Journal 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.
