Details

Tittle:
Multifuntional, multireinforced polymer panels for vehicles with crashworthy capacity
Summary:
A Greek company has produced a novel multireinforced polymer panel. The panel exhibits outstanding resistance to axial buckling and to in-plane or out-of-plane shear forces. Its manufacturing process is simple and the panels are light and low-cost. The company is looking for research partners to develop the technology further, especially as an application for automobiles.
Description:
The Greek company specialises in material development and multiaxial testing, within the framework of many international industrial projects and in more than 30 European, competitive, four year research projects of the EC, the last 25 years.
Its latest technology involves the creation of high-durability, low-cost, low-weight panels especially suited for the automobile industry.
The new core-panel has been designed and manufactured based on a novel architecture. The matrix is reinforced with Carbon nanotubes (CNTs) and the composite with long fibers in the X -Y- Y directions. New processing equipment, including a mixer-reactor, has been developed for CNT reinforcement. It is also efficient for hybrid CNT/graphene reinforcement, which will increase the core durability and therefore will reduce further the panel cost.
The forming process is generic, suitable for use with polymer matrices of low or high viscosity. Initially the thermoplastic Polyether ether ketone (PEEK) and a lower cost PolyEtherKetone (PEK) were used. Presently an inexpensive thermoplastic polyurethane is employed. The manufacturing process is simple and cost-effective.
The company is seeking research partners to develop the product further and apply it in the manufacturing process of vehicles.
The Greek company is also considering further development of the product through research proposals under H2020.
Advantages and Innovations:
The developed panels exhibit a number

1. Outstanding resistance to axial buckling and to in-plane or out-of-plane shear forces. Long fatigue life at high stress level was measured for PEEK/CNTs and PEK/CNTs matrices. These arise from:
a. Effective CNT reinforcement (>230 % increase) of the matrix, based on new concept processing equipment (mixer -Y- reactor).
b. Satisfactory liquid powder impregnation, improved further with local differential movement of the fibers during compression molding.
c. Cell-core design based on an optimization technique, where mass-stiffness-damping are parametrically expressed as a function of the core´s geometry and material properties.
2. The manufacturing process is simple, continuous, low energy consuming and capable to produce tailored panels with varying cell geometry, including fastening parts to other components (panel density < 0,1 gr/cm^3). If the facing sheets are not fiber reinforced, the panel possesses high formability.
3. The extensive work-hardening behavior of the reinforced PEEK matrix, the high specific energy absorption of the carbon fibers and mainly the core design (deformable), provide an outstanding crashworthy capacity. This can be further enhanced by shape morphing of selected cells when excessive deformation is reached, leading to the instant change of their dynamic characteristics (self-actuation).
4. The work-hardening behavior (improved with nano-reinforcement), postulates greater matrix volume to deform.
5. Vibrational energy absorption is enhanced due to the inclination of the cell walls. When loading is applied shear deformation prevails, which maximizes damping.
6. The proposed hybrid CNT/graphene reinforcement will increase durability (enhanced by crack tip deflection on graphene). Then, the ratio cost / (fatigue life time) is further reduced.
