Abstract: High thermal-dimensional stability is crucial for high-precision applications, e.g., unmanned monitoring of Moon surface environment, etc. This study designs a novel 3D carbon fibre reinforced plastic (CFRP) composite lattice with high thermal-dimensional stability. First, the planar CFRP composite lattice was designed with a continuous carbon fibre reinforced polyamide (PA) central cross-lattice interlocked with four short carbon fibre reinforced PA outer-strips, fabricated via fused filament fabrication. Second, a novel three-dimensional (3D) composite lattice structure was developed and calculated, exhibiting a negative effective CTE at −0.18×10−6/℃, based on the planar composite lattices. Third, lightweight optimisation was conducted for high thermal-dimensional-stability.
Keywords: Continuous carbon fibre, finite element analysis, coefficient of thermal expansion, FFF, thermal-dimensional stability.
