While nanocomposite elastomers have been extensively studied, the role of micro-sized fillers in reinforcing composite elastomers remains less well defined. In this work, model composite elastomers consisting of polydimethylsiloxane and micro-sized aluminum fillers ranging from 1 μm to 50 μm were systematically investigated. Mechanical testing revealed that decreasing filler size significantly increased fracture energy, with the highest value observed in composites containing 1 μm aluminum. We demonstrate that this enhancement was attributed primarily to interfacial energy between fillers and the polymer matrix, as established through a refined neo-Hookean constitutive model combined with molecular dynamics simulations. Contrary to the bridging mechanisms observed in nanocomposites, analyses of polymer chain gyration radius, inter-filler spacing, and filler absorption layer thickness demonstrated that polymer chain bridging does not contribute to mechanical reinforcement in micro-filled systems. Instead, a coupling effect between absorption layer thickness and inter-filler distance governs modulus variation. A continental shelf-like model is proposed to conceptualize this coupling effect, and atomic force microscopy measurements validated both the interfacial absorption layer thickness.

Polyimide endows the composite aerogel with outstanding thermal resistance and superior mechanical strength, with a weight loss of only 5 % at 440 °C and a compressive stress of up to 100 kPa at 60 % strain.

Based on the multi-scale model, optimizations are conducted for weaving patterns and structural dimensions. Analysis of the meso-scale model prediction shows that symmetric plain-woven carbon/carbon composites exhibit superior thermal stability with low thermal strain. When the spreading ratio of elliptical cross-section bundles is increased, the negative thermal strain of the composite is further reduced. Hence, weave structures of the cell wall and the panel are determined.
