Good Agreement

Some features of hydrogen bonding effects for the phenylon polymer matrix filled with a terlon fiber have been investigated at ab initio approximation. The results of calculations for isolated and dimerized structural forms of N-phenylbenzamide as a model compound are in good agreement with the spectral data for this composite material building.

In order to research the fatigue strength of gasket which is with new composite material in one plane, we designed and manufactured special testing equipment. The material of shaft of testing equipment is 30CrMnSi. In the experiment, the 30CrMnSi shaft was broken into two parts by suddenly. By structural analysis, static analysis and heat treatment analysis for shaft, we get the reason of fracture for shaft finally. The problem solved make the test goes well and can help design and manufacture testing equipment in the future.

Hybrid Composite Material

The fast growth of composite materials in the aerospace industry is due to its desired properties over conventional metals. In this paper, a detailed static structural analysis and vibrational analysis was carried out for the aircraft wing frontal spar using hybrid material and it was compared with different conventional materials used in aerospace industry like aluminium, CFRP (Carbon Fiber Reinforced Polymer). The carbon fiber and flax fiber were selected for composition in hybrid composite material since it shows an exceptional specific mechanical properties and good vibration damping properties. The frontal wing spar was designed using modelling software CATIA V5. Static structural analysis and modal analysis was performed using ANSYS software. Exploring the results of structural analysis, it was interpreted that the static structural efficiency of the hybrid composite material was exceptionally high compared to aluminium and it shows nearly equal specific mechanical properties compared to CFRP. This leads to reduction in cost of the structure. From the modal analysis the various natural frequencies for six modes are discussed. The analysis shows natural frequency of wing frontal spar using hybrid composite material exhibits similar deformation compared to CFRP. Hybrid composite material exhibits higher damping factor when compared to chosen materials. This behaviour of hybrid composite material shows that it could be effectively replaced in wing frontal spar instead of conventional materials like CFRP and aluminium.
