Development of a scaled vehicle underbelly blast test method

Over the last three years TNO has explored the possibilities of fiber-reinforced composites to provide vehicle underbelly protection against blast loading. This work consists of three parts: • Numerical analysis of full-scale blast loading conditions in comparison to scaled blast loading conditions. • The development of a test method suitable to...

Development of fiber-reinforced composite material for blast protection

This paper shows how standard fiber-reinforced composite materials have limited resistance against blast loading. Their relatively high brittleness in comparison to metals causes them to fail early under out-of-plane blast loading. Their failure appears to be mainly caused by exceedance of strain to failure by local bending, fully absorbing the...

Investigation of vulnerability of aircraft structure and materials towards cabin explosions

Damage Tolerance of aircraft fuselage structures has a strong link to explosion resistance. Though accidental explosions can and do occur, intentional explosions are more common as the terrorist threat increases. Structural toughness is as welcome in these scenarios as it is under penetration of non contained engine debris. Guidelines in...
