Abstract Laser joining merges as a novel technique for the connection of carbon fiber reinforced thermoplastics composite (CFRTP) and metal. Besides, machining grooves on the metal surface presents a surface pre-treating method to enhance the strength of laser joining joint between CFRTP and metal. In this study, the laser joining of CFRTP and Ti6Al4V alloy is performed with different groove dimensions. The effect of groove dimension on interface morphology and failure load is analyzed. In addition, the formation mechanism of the interface and the fracture mode of the joint are further elucidated. The results indicate that the structurally sound connection and maximum failure load are attained with an appropriate groove dimension (groove width: 0.7 mm, groove depth: 0.25 mm, and aspect ratio: 0.36). At a narrower groove, the bubbles inside the resin caused by thermal decomposition of the matrix resin are obtained, while at a deeper groove, the gaps and holes are observed in the interface of the joint, both resulting in a lower failure load.

To use Carbon Fiber Reinforced Thermoplastics (CFRTP) for automobile applications, mechanical properties of CFRTP under actual operating temperatures are needed to be clarified. When focusing on heat resistance of CFRTP, to use Polyphenylenesulfide (PPS) for the matrix is desirable. However, the effect of high temperature on mechanical properties of CFRTP using PPS has not been clarified yet. In this study, single fiber pull-out tests of CF/PPS model composites under high temperature were conducted to reveal the fiber/matrix interfacial properties.

AbstractThermoplastic resins used as a matrix of fiber reinforced thermoplastics (FRTPs) are composed of high polymers that remain highly viscous even at a higher temperature than their melting points. As a result, they need an even higher temperature, a higher pressure and a longer processing time to allow them to bond with fibers that require large and specialized equipment. In contrast, fiber-reinforced thermoset plastics (FRPs) can be easily molded owing to the use of lower viscosity liquid resin as the matrix using simpler devices. In this paper, a new fabrication method of FRTPs using

Function of functionally-graded (FG) foams as energy absorption material for impact was discussed on the basis of theoretical analysis, and fabrication process of the foams was proposed in the paper. The FG foams were found to be useful as impact absorber due to progressively local fracture or cushion in the theoretical analysis. Next the fabrication process of the FG foams was suggested. The graded dispersion of the micro-balloons was conducted before curing the matrix resin in the process. The density distributions in the FG foams were confirmed to be predicted by the numerical analysis on the basis of floating the micro-balloons. Finally, compression tests were carried out to evaluate mechanical properties.
