The latter approach, where strong enough, is the most elegant as very specific areas may be reinforced in a honeycomb panel down to the size of an individual honeycomb cell. Honeycomb spliced multilayer foam core aircraft composite parts and method for making same. Year of fee payment : 8. The foam was thermoset in nature and it adhered to all the honeycomb cell walls as well as to the aluminium sheets. Held in its expanded form, this fragile paper honeycomb block is then dipped in a tank of resin, drained and cured in an oven. Comments 0 Sign in or create an account to join in the discussion.

    The height 18 of the completed part 11 is greater than the height 20 of the billet 10 ; however the subject fabrication process will allow such a part to made from the billet The ends 32 and 34 of the mold 28 include mechanical stops 39 and 40respectively to prevent movement of the core 10 B off the mold surface

    Honeycomb cores range from paper and card for low strength and The cells of the honeycomb structure can also be filled with a rigid foam.

    The filled or partially filled mould or honeycomb core can then be cured to produce bonded sandwich panels or moulded cellular artefacts. In sandwich panel. products offers honeycomb core for door filler products. About 41% of these are aluminum composite panels, 27% are doors, and 12% are.
    The present invention provides a process for the fast and efficient localised filling of sandwich panels which can be carried out at room temperature.

    The operation of filling with these syntactic pastes also results in contaminated equipment, protective clothing, containers and so forth all of which need careful and legal disposal operations. Twitter Facebook LinkedIn Email. Thermally expanding powders suitable for use herein may be prepared, for example, by grinding a solid thermally expanding resin composition. In any case filling honeycomb core with foam is old in the art and need, therefore, not be discussed in further detail.

    The initial paper honeycomb is usually dipped in a phenolic resin to produce a honeycomb core with high strength and very good fire resistance. While this technique does simplify the application of syntactic materials in sandwich panel reinforcement applications it cannot easily be used for the attachment of honeycomb to itself or to edges and the like.

    In another approach, a pre-formed flexible uniform thickness film of thermosetting, hot curing, foaming, adhesive is utilised.

    Their main disadvantage is the difficulty of achieving a good interfacial bond between the honeycomb and the skin.

    A process according to claim 6 further comprising, after the filling step and before the heating step, the step of pressing a facing material against the open face. JPB2 en. The mold 26 is positioned such that the weights 41 are vertically over the point of maximum curvature, indicated by line

    Foam filled honeycomb Sometimes honeycomb cores have their cells filled with foam for different reasons.

    Usually it is done to increase the core thermal. Request PDF on ResearchGate | Sound transmisson loss of foam-filled honeycomb-core sandwich panels | Composite panel structures are often used in .
    A process for completely filling a void having an open face with a coherent low density solid comprising the steps of adding a free flowing thermally expanding, foamable and curing powder to the void to completely fill the void with the powder, and heating the powder causing the powder to expand, sinter and cure, wherein said free flowing thermally expanding, foamable and curing powder is an epoxy resin composition, and wherein the heating step provides a completely filled void.

    A process according to claim 1 wherein the free flowing thermally expanding, foamable and curing powder is an epoxy resin manufactured from 2,2-bis- 4-hydroxyphenyl propane and epichlorohydrin. Once this dipping resin has cured, the block has sufficient strength to be sliced into the final thicknesses required.

    Filling honeycomb core
    In the case of sandwich panels with a plastic foam core it is usually sufficient to carry out these connection, joining and reinforcement operations by the use of a thermosetting paste which stays in position during the curing cycle.

    The powder may itself be capable of filling the space under no external pressure constraint or it may be capable of over filling the space but be constrained by external pressure applied to the skins during the cure cycle without any adverse effect.

    5 thoughts on “Filling honeycomb core

    1. Thereafter, the foam filled core had fully deformed to the contour of the mold surface 28as illustrated in FIG. An additional disadvantage of the need to warm the paste to room temperature is that those pastes having a high reactivity at room temperature have their usable life decreased.

    2. A process according to claim 1 wherein the free flowing thermally expanding, foamable and curing powder is an epoxy resin manufactured from 2,2-bis- 4-hydroxyphenyl propane and epichlorohydrin.

    3. Miniature cell array structure and manufacturing method of miniaturized composite component using such a miniature cell array structure. In the case of sandwich panels using honeycomb core for high performance ground and marine transport and sports goods and particularly those used in aerospace, where strength, light weight and resistance to degradation is extremely important, these syntactic pastes have been used for most of the attachment and reinforcing needs as described hereinbefore for at least the last 30 years.

    4. The cells of the honeycomb structure can also be filled with a rigid foam. Method for producing a unitary box-like structure manufacturing method as composite structures of fiber composite material.

    5. This consideration also applies to higher density syntactic pastes where they may be pumped through pipes or tubes or other constrictions.
