The morphology of MAX phase composites is examined here. Specifically, crack branching is examined in Al - Ti2AlC composites showing the role of MAX phase distribution on the fracture performance of such materials. Ductile alloy phases serve to deflect cracks in the hard, yet tough, MAX phase.

The ICME Conference 2020, a HxGN LIVE event is a 3-days intensive online conference on October 6-8, 2020 for executives, R&D, manufacturing professionals, engineers, and designers to learn, explore and share about Integrated Computational Materials Engineering (ICME) to enable companies to blur the boundaries between manufacturing, materials and part performance for the optimal design of innovative quality products.
#IPPTPAN in collaboration with Department of Engineering at #NTU is offering four fully supported #PhD positions in the following fields:

Vitrimers are a groundbreaking development in polymer chemistry. This new class of polymers is neither thermoset, nor thermoplastic, but inherits properties from both polymer classes. Vitrimers were "invented" by Prof. Leibler in Paris in 2011 (https://en.wikipedia.org/wiki/Vitrimers).
Many applications can be imagined, but the application of vitrimers as the polymer matrix in fibre-reinforced composites, is particularly attractive, because the recycling of fibre-reinforced composites could be drastically improved.
A postdoctoral position in “Multi-Scale Modeling of Composites” is available in Tehrani Group in the Walker Department of Mechanical Engineering at UT Austin. The position starts in August 2020. The required qualifications for this position are as follows:
· Acquired a Ph.D. in Mechanical Engineering or a closely related field before the position start date.
Over the last years, UGent-MMS has developed the stand-alone BladeMesher software for generating finite element models of large wind turbine blades. The software reads in the material data and airfoil data of the wind turbine blade, and automatically constructs the geometry and finite element mesh for the blade. In a next step, the nodal and element information of the finite element mesh is written out to an input file for a commercial finite element solver (Abaqus in this case).
Thermoplastic composites are gaining more and more interest in automotive, aerospace and sports applications, because of the short cycle times and recycling possibilities. Besides short fibre-reinforced thermoplastics, also continuous fibre-reinforced thermoplastic composites are being considered for load-carrying structures. However, their behaviour during manufacturing and during in-service use is very different from the traditional thermoset composites (typically epoxy-based). The mechanical properties of thermoplastic composites are much more sensitive to temperature and loading rate.
