“…It can be then defined target reduction of density. By using Equation (4) and taking into account that CB and CNT(N) have the same density, reduction of composite density form 1.14 to 1.07 g/cm 3 can be achieved by substituting 30% by mass of CB with the same amount of CNT(N). This composite would have 7.7 and 3.3 as volume% of CB and CNT(N), respectively.…”

“…Raman spectra of CNT(N) and CB are reported in Figure 2. The G peak is assigned to the E 2g Raman active mode of collective C=C stretching vibration of crystalline graphite (graphene), whereas the D peak appears when structural defects, such as holes, sp 3 or sp carbon atoms, dangling bonds, distortions from planarity, grafted functional groups or confinement (e.g. by edges) affect the graphitic layers [36][37][38][39][40][41][42][43][44].…”

“…The variation of matrix density is below 6%, and this gives an uncertainty of the density of the composite even lower. The density of the SBR matrix, ρ m , was estimated equal to 0.98 g/cm 3 . G′ γmin interfacial area values of Equation (4) Table 1 and Table 2 with CB, CNT(B) and HSAG (from [25]) as the carbon allotropes φ CNT /(φ CB + φ CNT ), ranges from 0, for composites based only on CB, to 1 for composites based only on CNT(N).…”

Abstract. This work presents high surface area sp 2 carbon allotropes as important tools to design and prepare lightweight materials. Composites were prepared based on either carbon black (CB) or carbon nanotubes (CNT) or hybrid CB/CNT filler systems, with either poly(1,4-cis-isoprene) or poly(styrene-co-butadiene) as the polymer matrix. A correlation was established between the specific interfacial area (i.a.), i.e. the surface made available by the filler per unit volume of composite, and the initial modulus of the composite (G′ γmin ), determined through dynamic mechanical shear tests. Experimental points could be fitted with a common line, a sort of master curve, up to about 30.2 and 9.8 mass% as CB and CNT content, respectively. The equation of such master curve allowed to correlate modulus and density of the composite. Thanks to the master curve, composites with the same modulus and lower density could be designed by substituting part of CB with lower amount of the carbon allotrope with larger surface area, CNT. This work establishes a quantitative correlation as a tool to design lightweight materials and paves the way for large scale application in polymer matrices of innovative sp 2 carbon allotropes.

“…Due to the lightness of aluminium alloys relative to steel, the total weight of a vehicle can be reduced by 28% [3]. This allows to reduce fuel consumption and consequently the emission of harmful contaminant agents into the atmosphere [4]. Several numerical and experimental studies have been conducted with the purpose of maximising the crashworthiness performance of thin-walled structures [5,6].…”

Abstract. In this paper finite element software Abaqus was used to analyse the effect of cross-sectional shape on the crashworthiness performance of multi-cell profiles. An emphasis was placed on the modelling of the damage initiation criteria and its evolution during the crash event. The structures evaluated included square and circular multi-cell cross-sections fabricated with aluminium alloy EN AW-7108 T6. During the crash simulations, the structures were subjected to axial impact loads using a 500-kg rigid body striker with an initial velocity of 10 m/s. Accordingly to our results, profiles with circular cross-section base presented better crashworthiness performance than square profiles. An increase in crush force efficiency to 36.9% and specific energy to 35.4% was observed when a circular cross-section has been reinforced in the transversal and longitudinal directions. Finally, it was corroborated that the addition of the damage initiation criteria allowed for more reliable crash simulations of the structures.

Numerical and Experimental Investigation on the Self‐Healing Potential of Interpenetrating Metal–Ceramic Composites

et al. 2023

An interpenetrating metal ceramic composite (IMCC) has been investigated regarding the potential as well as the feasibility of self‐healing. Triggered by heating, cracks in the damaged composite located mainly in the Al2O3 ceramic or at the interface could be filled and closed by the liquid AlSi10Mg metal alloy. This healing procedure promises to reduce stress concentrations at crack tips and to improve the mechanical properties compared to the predamaged composite. Two different numerical approaches have been introduced to investigate this assumption and the potential of self‐healed IMCCs for a best case scenario: 1) A simple 2D model to analyze the reduction of stress concentrations in front of a crack tip within the ceramic due to healing and 2) a 3D model based on CT‐scan reconstructed microstructures to study how macroscopic mechanical properties can be restored depending on the amount of predamage. Further, the self‐healing approach has been investigated experimentally for the same composite. Despite the fact that experimental self‐healing of the investigated IMCC is only moderately feasible so far, the study shows the great potential that can still be exploited in order to extend the service life time of IMCC engineering components.
