Hugoniot equations of state and spall strength, concerning high-pressure shock compression and high-strain-rate tension, are derived from free-surface velocity measurements.

As impact velocity increases, spall strength for both the composites first increases and subsequently decreases due to the competing effects of shock-induced heating and strain-rate hardening. Crack nucleation and propagation depends on interface strength, fiber length and fiber orientation.

To address these weaknesses, a novel embedded microvascular network was developed using hollow channels designed to deliver a low-viscosity 80%ENB–20%DCPD healing agent. Numerical simulations coupled with experimental validation were conducted to assess impact damage, flow behavior, and healing efficiency. Results revealed that the deltoid and adhesive interface regions exhibit the highest stress concentration and damage propagation under impact.

This work introduces a non-destructive, pipe-level identification methodology that determines the full in-plane orthotropic elastic response of multi-material composite pipes using only axial loading and internal pressure tests. A trace-based stiffness formulation is developed for pipes composed of a PVC liner and a fiber-reinforced polymer composite wrap, enabling direct identification of axial and hoop Young’s modulus and the associated Poisson’s ratios from pipe level measurements. The in-plane shear modulus is subsequently inferred from the invariant trace of the reduced stiffness matrix (Tsai’s modulus), eliminating the need for torsion testing or coupon extraction. The results provide structural scale validation that the trace-based formulation, originally developed for unidirectional carbon fiber composites, can be successfully extended to woven glass fiber reinforced polymer (GFRP) composites. Four nominally identical pipes were tested under axial tension, axial compression, and internal pressure, with three repeated runs per loading mode. Despite identical constituents and processing conditions, measurable pipe to pipe variability was observed. These findings demonstrate that reliance on unidirectional ply data or coupon level surrogates is insufficient for reliable structural prediction of multilayer composite pipes and that pipe-level characterization is required. Finite element simulations using the identified properties reproduced the measured axial and hoop surface strains within the experimental 95% confidence bands for all load cases.

As part of an eco-design approach, we studied the processing of a flax/polypropylene (PP) composite. The ability of companies to adapt to demand is also a key factor in the ecological transition. While the manufacture of this composite using the bending method has already been studied, the way in which it is shaped has received little attention. In this study, the feasibility of bending composite samples (size 100 × 15 × 3.4 mm) at an angle of 90 degrees is evaluated. For its thermoplastic properties, the PP has been chosen, so it can be transformed more than one time, contrary to the epoxy. As a result, the manufacturing and storage of flat plates upstream will then allow elements to be shaped on demand, since only the bending stage would remain. Flax fibers are found in large quantities in France and are natural fibers with interesting properties. Process conditions were experimented with to achieve external bending without detrimental damage to mechanical behavior. Those conditions are related to the process fabrication: tools temperature (die and punch up to 145 °C), preheating of the material (160 °C), heat flux around the sample (flow up to 0.115 m<sup>3</sup>/s), implementation process (holding time between 240 and 360 s and cycles), fold orientation (45° or 0°), … The influence of the various parameters on fold quality (visual and mechanical) is analyzed by experimental design and strength tests (threshold higher than 117.3 MPa).
