Summary: In this paper, the densification mechanics of polymeric syntactic foams under compressive loading are investigated using computational models and regression analysis. It is found that microballoon crushing strength and volume fraction have the highest influence on densification stress and energy, while interfacial bonding has the least impact. In addition, the design aspects of syntactic foams with specific overall density are discussed by mapping microballoon volume fraction and wall thickness.

Summary: This paper investigates the mechanical properties of a 20% fiber glass reinforced diglycidyl ether of bisphenol A epoxy resin (GF/EP) after high temperature aging. Tensile and flexural stress-strain curves of the composite were measured between 85-145 °C in air. The results show a gradual decrease in tensile and flexural strength with increasing aging temperature. Microscopic analysis reveals separation between the glass fibers (GFs) and the epoxy matrix (EP) as well as evident pullout of the GFs. The degradation of mechanical properties can be attributed to cross-linking and chain scission in the composite's initial molecular structure, oxidation of the EP matrix, and the difference in coefficients of thermal expansion between the GFs and EP matrix.

Summary: The study investigates the impact of controlling resin content on the microstructure and mechanical properties of composite materials. The behavior of resin is found to determine the thickness, density, and void of the composite laminate, which leads to differences in mechanical properties. Tensile strength shows no significant differences with increasing resin content, but Young's modulus decreases. In compression tests, the combined effect of reinforcement and resin influences mechanical properties, with lower void content resulting in higher compressive strength and increasing resin content leading to a decrease in Young's modulus.

The method introduces an improved integral approximation scheme to enhance the convolution solution accuracy, which is applicable to any causal kernel function. The mathematical derivation and calculation procedure based on the composite explicit method are formulated for non-viscous damping systems. Numerical simulations of representative examples demonstrate that the adopted composite explicit method exhibits better stability and accuracy properties compared to other explicit methods.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
